One of the Exchange Server administration tasks I perform almost every day is creating mailbox size reports. There are a few different reasons that I create these reports, such as planning a mailbox migration project, responding to a storage capacity alert for a particular database, or providing a specific team of people with a report of their mailbox sizes.

Now it is pretty easy to get the sizes for Exchange mailboxes and to handle the formatting of the Exchange 2010 mailbox statistics so that they are easier to perform calculations on, but it gets a bit boring running those commands day after day.

Even worse, after running the commands to create a CSV report I still had to open that in Excel, remove the unwanted details, use Excel formulas to convert the values from bytes to megabytes, sort them into order, and so on. Again not difficult, just boring after doing it hundreds of times.

So I created a PowerShell script, Get-MailboxReport.ps1, to do all of the heavy lifting for me, and I’m sharing that script with you here.

This script is available on the TechNet Script Gallery or Github. Comments are welcome below. If you find a bug please consider raising it as an issue on Github.

Let’s take a look at how the script works. Here is a video to demonstrate:

I’ve included help information within the script itself so you can use Get-Help to discover how to run the script.

[PS] C:\Scripts\demo>Get-Help .\Get-MailboxReport.ps1

NAME
    C:\Scripts\demo\Get-MailboxReport.ps1

SYNOPSIS
    Get-MailboxReport.ps1 - Mailbox report generation script.

SYNTAX
    C:\Scripts\demo\Get-MailboxReport.ps1 [-database ] []

    C:\Scripts\demo\Get-MailboxReport.ps1 [-file ] []

    C:\Scripts\demo\Get-MailboxReport.ps1 [-server ] []

    C:\Scripts\demo\Get-MailboxReport.ps1 [-mailbox ] []

    C:\Scripts\demo\Get-MailboxReport.ps1 [-all] []

DESCRIPTION
    Generates a report of useful information for
    the specified server, database, mailbox or list of mailboxes.
    Use only one parameter at a time depending on the scope of
    your mailbox report.

RELATED LINKS
    For more script details, a video demo, or to give feedback please go to:
    

REMARKS
    To see the examples, type: "get-help C:\Scripts\demo\Get-MailboxReport.ps1 -examples".
    For more information, type: "get-help C:\Scripts\demo\Get-MailboxReport.ps1 -detailed".
    For technical information, type: "get-help C:\Scripts\demo\Get-MailboxReport.ps1 -full".

Depending on which parameter you use the output will vary.

  • If you use the -mailbox parameter to query a single mailbox, then the output will appear in the console window. I don’t really see the need to output a single mailbox’s details to a CSV file.
  • If you use any of the other parameters, -server, -database, -file, or -all, the output will be written to a CSV file in the same folder you’re running the script from.
  • You can use the optional -filename parameter to specify your own output file name

Once you’ve generated the CSV report you can open it with Excel and begin to analyze the data.

    This is a beautiful script!

  2. Charles

    I’m running the report (Exchange 2013) with the “-all” switch, but its not showing the total mailbox size, inbox size, etc. It does show the archive sizes as “n/a”. Was there a different switch to get the mailbox size included?

  3. Noe L

    good morning friends,

    I would like to make a report to extract fields from both AD and Exchange
    for example:
    Name Company Department Description Domain Email Address Job Title MAILBOX SIZE SPACE IN (MB) Office Street PHONE

    This is possible?

    1. Dennis

      You ever get a response on this?

  4. Kashif

    Hi Paul,
    Thanks for sharing the mailbox statistics script. I am having a bit different scope as i am searching a script that will send an email alert to helpdesk distribution group when a mailbox approaching its limit of prohibit send. can you please help to get it done.

    BR,

    Does this work off the Scheduled Tasks? If I run it manually, it works fine. But from scheduled tasks it keeps saying: Could not find file ‘C:\SCRIPTS\Alex\MailboxReport-20200405-1637-evhlr9.csv’.

  7. Keith Luken

    I love this script. I would like to see it scan all AD accounts and get mailbox info whether is is on prem Exchange or O365 and just annotate each with relevant field comments if n/a.

    Hi Paul

    Can this script be used for Exchange Online?
    If so, how can I do it?

    Hi Paul,

    I run this script into Exchange 2016 server, takes lot of time to execute it, any chances reduce it.

  12. Martin Soubre

    Hi, very thank for your script, it’s an awesome work, save me hours of work
    By the way, it work well on windows server 2016 with exchange 2016 CU11, maybe you can tag it on the technet

  13. Richard Pettigrew

    Thank You Very Much for saving me many hours of my time! Appreciate it. 🙂

  14. Krasimir Donchev

    Hi Paul,
    the script is OK, but please change the column delimiter with ~. Using , as delimiter is not a good idea when exporting to CSV file, where most of the envrionments use DisplayName like: Lastname, Firstname.

    HI Paul,
    a very tricky question you please help me on below requirement.
    if i run any exchange powershell command the complete output should be captured in transcript, Example If i run start transcript and then new=mailboxexportrequest with mailbox name and path then command will execute and in transcript i could see only output as mailbox is in pending status but i would like to capture all back end process until mailbox exported to the given path. Is there a way to do it. Kindly help me on this.

      This is probably because you may have just saved the script directly and it’s downloaded as HTML, rather than a PowerShell script?

    How to make the script to support the Mailboxes in Exchange Online?

  25. Keith McConville

    Hi Paul,

    I am getting an error file generated (get-mailboxreport-error.log) every time I run the script from any location. The text in the file goes something like “Could not find file ‘C:\scripts\MailboxReport-20180606-1508-6HNLvO.csv’.” Any ideas?

    1. Keith McConville

      Ignore that. When I used the -mailbox parameter, it didn’t work. I should have read you article above where you stated:
      “If you use the -mailbox parameter to query a single mailbox, then the output will appear in the console window. I don’t really see the need to output a single mailbox’s details to a CSV file.”

      Fantastic script and output!!!

  26. Sergio C.

    Thank for for providing this awesome script. I used it all the time when we were on 2010 but does not work with our new Exchange 2016 server. Will you be updating the script to make this work or is there something I can change in the code to make it work with 2016?

  27. Chris C

    Paul,
    First I just wanted to say this is a fantastic script! Saved me a TON of time. I did have a quick question on it however, is it possible to change the output of size from mb to gb? Is it a simple matter of replacing?

    Thanks!

  28. Wasim Parkar

    Hi Paul
    This script is exactly what I am looking for but I cant get it to work.
    I can get the Get-Help up but if i run the command with the -all parameter it does nothing. I just get a new powershell window. A file gets created but with 0bytes.
    Any ideas. The command I run is:
    .\Get-MailboxReport.ps1 -All > C:\Temp2\newdata.csv
    It just comes to a new PS line (as if waiting for a new command).

      1. Mounir

        i have the same issue. even i use \Get-MailboxReport.ps1 -All > C:\Temp
        or just \Get-MailboxReport.ps1 -All

        It just comes to a new PS line (as if waiting for a new command).

  29. Nasser Al Toubi

    Dear Paul,

    Thank you for the great script it’s a very helpful script, it was working fine with me until last month as it’s configured for monthly basis but I get an issue with it, it give me error “Get-MailboxReport.ps1 : Parameter set cannot be resolved using the specified named parameters” I solved this issue by modifying the param as below:

    function foof{
    [CmdLetBinding(DefaultParameterSetName=”None”)]
    param(
    [Parameter(ParameterSetName=’database’)]
    [string]$Database,

    [Parameter(ParameterSetName=’file’)]
    [string]$File,

    [Parameter(ParameterSetName=’server’)]
    [string]$Server,

    [Parameter(ParameterSetName=’mailbox’)]
    [string]$Mailbox,

    [Parameter(ParameterSetName=’all’)]
    [switch]$All,

    [Parameter( Mandatory=$false)]
    [string]$Filename,

    [Parameter( Mandatory=$false)]
    [switch]$SendEmail,

    [Parameter( Mandatory=$false)]
    [string]$MailFrom,

    [Parameter( Mandatory=$false)]
    [string]$MailTo,

    [Parameter( Mandatory=$false)]
    [string]$MailServer,

    [Parameter( Mandatory=$false)]
    [int]$Top = 10

    )
    }

    however I get another error “No mailboxes were found matching that criteria.”

    Hi,
    is it possible I can use -match switch in my search ?

    Example, i’m look for ManagedFolderMailboxPolicy in match specific policy and output out to csv file. how do I insert “match” switch in the script ?

    Example:
    if($database){ $mailboxes = @(Get-Mailbox -ResultSize Unlimited | ? {$_.ManagedFolderMailboxPolicy -match “Exchange2007-Unlimited) }

      Paul Cunningham

      Please don’t post the same question on multiple articles. Yes, modify the Get-Mailbox line to suit your purposes.

      1. Jimmy Wang

        Sorry for posting different places. though it was different blogs.

        what is correct line ? I think Im doing it wrong when I insert this line
        if($database){ $mailboxes = @(Get-Mailbox -ResultSize Unlimited | ? {$_.ManagedFolderMailboxPolicy -match “Exchange2007-Unlimited) }

        can you help me to identify what am I doing wrong ?

        1. Avatar photo
          Paul Cunningham

          You’re modifying the line that is run when the -Database parameter is used to query the mailboxes on a single database.

          if($database)

          There are multiple Get-Mailbox commands depending on which script parameter is used, so you will need to modify the command that is applicable to how you’re using the script.

  33. Shane King

    Anyone know how to get the emailing of the report to work with SSL port 465?

    1. Avatar photo
      Paul Cunningham

      Short answer: add a parameter to the script, call it something like MailPort or SMTPPort. Make it a default value of 465 if you want.

      Add to the email settings at around line 173, the extra setting for Port = $MailPort

    How to email with multiple recipients in one string instead ? some of the user is not in same distribution group and would like to including them. My work around, is to modify/add this parameter but I can’t add more than one user per string.

    [Parameter( Mandatory=$false)]
    [string]$MailTo,

    [Parameter( Mandatory=$false)]
    [string]$MailCC,

    [Parameter( Mandatory=$false)]
    [string]$MailBCC,

    when I run this script I get the version error. my windows powersehll is version 4 and exchange powershell is version 2.

    I took exact same script to run on different machine that is running Windows powershell version 2 and exchange powershell version 2 and it runs fine.

    Does this mean this script Get-MailboxReport.ps1 doesn’t support Windows powershell version 4 ?

      Did you modify the script? If so, looks like you’ve misspelled “version”?

      1. Jimmy Wang

        Hi Paul, thanks for getting back.
        I downloaded the script again without changing anything. still running the same error.

        I didn’t mention, I’m running this in task scheduler. i have no problem running it from Exchange powershell, always can get the results back. with this
        .\Get-MailboxReport.ps1 -database databasename -SendEmail -MailFrom username@abcxzy.com -MailTo username@abcxzy.com -MailServer relayny.servername.com

        when I run it from task scheduler, the Window powershell pop up and error out with this error . from out my machine, it runs fine.

        it looks like it bomb out on Windows powershell

    Hi Paul,

    should this script also flag archive mailboxes on the databases?
    ive just run the script against an archive db and it doesn’t flag any users?

    works fine on the other databases

    1. Avatar photo
      Paul Cunningham

      Without really looking into it, I’d guess that the script is not handling that scenario properly. I’ve made a note in my GitHub issues register to take a closer look at some stage.

      As a workaround I’d suggest, if practical in your environment, just running a report of the entire org and filtering in Excel to get the view that you’re looking for.

  40. Paul Lee

    This script is amazing! I was wondering if there is a way to report on mailbox items that are less than 30 days old? In other words, total items and size for the most recent 30 days, discarding anything older than that.

      You’ll need Exchange Web Services for that level of detail. There’s good code samples out there for EWS scripts that report on mailbox item age.

          Use the name of the database, e.g. “Mailbox Database 1”, not the filename/path. The database name is whatever you see when you run Get-MailboxDatabase.

    Hi Paul,

    I’ve run the script and it works great but when I try to run it as scheduled task it’s not doing much. Have you ever run it as a scheduled task?

    Cheers

    Gav

    1. Julio Villar

      If it works as a scheduled task, you must configure in the action option and enter the path with which program the script will be executed and in a comment argument enter a similar syntax.

      The script path may vary in this case, place the script in drive “C:” inside the “Script” folder

      -command “C:\Script\Get-MailboxReport.ps1 -All -SendEmail -MailTo xxxxxx@xxxx.xxx.xx -MailFrom xxxxxxxxxxxx@xxxx.xxx.xx -MailServer xxxxx.xxxx.xxx.xx”

      You’ve downloaded a bunch of HTML code from the page on GitHub, not just the script code itself.

    Actually what need is all mailboxes including the one which migrated, discoonected, softdeleted, disabled.

    Hello Paul,

    This script is amazing and does get all the details.

    How can we have the script run against a specific OU to retrieve the details of users belonging to a specific OU only.

    This would be really helpful for me. Thank you!

    Hello Paul,
    thank you very much for this script.

    When I try to run it, I get a “NullReference” Exception.

    The last line in the Powershell window is “Collecting mailbox list”.

    Its a 2012 Server with Exchange 2010 (14.3 123.4).

    Thanks for this work! I added some code to add two additional fields: SIP Address (containing the Skype for Business SIP Address of the user) and “All Email Addresses” which contains a comma seperated List of all email alias addresses a mailbox has. If you want to incorporate these changes please feel free to contact me to send the modified script to you 🙂

    Thanks!!

  55. Joe G.

    Paul,

    First, thanks for everything through the years, you have been a huge source of guidance.

    This script works great, I get the CSV I want in the drop folder, no problem.

    The -MailFrom seems to have issues. It doesn’t like my input value to some degree.

    I get a get-mailboxreport-error log of:
    “Cannot validate argument on parameter ‘From’. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.”
    I am trying to mail the results to multiple addresses as a scheduled task behind a BAT file as follows:
    C:WindowsSystem32WindowsPowerShellv1.0powershell.exe -command “. ‘C:Program FilesMicrosoftExchange ServerV15binRemoteExchange.ps1’; Connect-ExchangeServer -auto;” “C:scriptsGet-MailboxReport.ps1 -All -SendEmail -MailTo xxxx@xxx.com;xxxx@xxx.com;xxxx@xxx.com -MailFrom ExchangeReports@xxx.com -MailServer smtp.xxx.com”

    Where all addresses are internal
    Where smtp.xxx.com is an internal open relay (works for all other scripts, apps, telnet :25, etc.)
    Exchange is 2013CU11 4 multi-role member / 2 site DAG
    Running from 2012R2 server with all AD modules + Exchange 2013CU11 tools (modules)

    I haven’t modified the script, except for code signing it. (Required)

    Any ideas ?

    1. Joe G.

      Paul,

      Nevermind, 🙂

      I put a ‘pause’ in the BAT and could see that it did not like multiple addresses. I will have to create a distro group and send it there.

      Thanks!

    There’s no “exumenabled” attribute of mailboxes. There is one called “UMEnabled” though.

    I am trying to add a umenabled field to this report. I have been able to add other fields, but having issues with this.
    I have tried adding $userObj | Add-Member NoteProperty -Name “Umenabled” -Value $mb.exumenable
    But the field I s blank. Also tried ummailbox with the same result

      Try running it against one database at a time to see which one might be slowing things down.

    I ran the report, and it worked great. You have item counts for the mailbox. But could you add item counts for the Inbox, Sent Items and Deleted Items folders?

    Hey Paul
    I getting error unable to relay email, after completion of script. And how to add two different database names i. e get-mailboxdatabase db-1 and db-9, and 3rd error is unable to split , while retrieving database drive space.

  62. RHV

    I am running the script from my laptop. I get all mailboxes with most of the data, but for all Size columns I get “n/a”.

    Issue warning Quata, Prohibit send, Account Expires, last logon are also blank.

    I have tried to run the scipts as Administrator, both in Power Shell and in ISE

    I don’t want to install the Exhange Management Console on my Exchange server so I am running it from my laptop on Windows 7.

      Your Exchange server would already have the Exchange management shell on it.

      Regardless, if you want to run it on your workstation, have you installed the Exchange management tools on it?

      1. RHV

        Yes, the Exchange management tools are installed.

        The script is also running and I get most of the info for all my users
        – just not the about about sizes and so on…

      2. RHV

        I found the problem….

        My user did not have enough rights. I logged on my computer with Domain administrator and then I got all relevant information.

        Thanks…

  63. Daniel

    first off the script is awesome, thank you.
    i am trying to email the results to an outside email address. however i get unable to relay error. the script is running on the exchange server. i can send the email to an internal address with no problem. would you know what i need to change to allow it to relay to an external address? when i do a manual command to send an email to an external address i can use the -credential $credential command and it pops up a window for login, that works but i cant do that from a scheduled task. to add to the confusion i have been able to setup the script in a scheduled task on two exchange server and get the email but i have tried on three other servers and it will not relay. i have checked the send connectors on all the servers and none of them, including the ones that work, have an open relay for the exchange server’s IP address. they have relay for other devices but the exchange server’s IP is not in there, nor is 127…
    curious if you have any advice. thank you for the script, its very very helpful in keeping track of the ever exploding email boxes.

      Paul Cunningham

      If you’re trying to relay to an external address, then you either need to authenticate the SMTP session, or you need a relay connector that allows that IP to relay.

      But I don’t recommend adding an Exchange server’s IP to any relay connectors, that will most certainly break internal mail flow.

      Personally, I run these types of scheduled scripts from a separate management or monitoring server.

      Plus, you could try sending the report to a distribution group. That is an internal email address, so it should be accepted, and it can contain contacts for external addresses.

  64. Carlos

    Hi Paul,

    First, many thanks for another fantastic script!
    I’m running it in an Exchange 2013 CU7 (Server 2012 R2) environment. The script runs fine and dumps the csv format report in the directory. However, I do not get it emailed to me although the report data in the shell shows “Sending email report… Finished.”

    Please help – Thank you!

    1. Avatar photo
      Paul Cunningham

      Most likely means you are not specifying valid/working SMTP settings when you run the script.

      1. Carlos

        Please see below.
        I am running the script from a second script called ExecuteMailboxReport.ps1 so I can run it in a scheduled task:

        Get-ChildItem C:tempMailboxReport *.ps1 -Recurse | Unblock-File
        Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted | .Get-MailboxReport.ps1 -All -SendEmail -MailFrom NoReplyExchange@myDomain.com -MailServer smtp.myDomain.com -MailTo MailboxReport@myDomain.com

        Do I specify the SMTP settings in this script like i did above, or rather in the original one (Get-MailboxReport.ps1)?
        Also, the email specified in the -MailTo switch belongs to a group. Does that make a difference or do I have to use the group members individual emails?

        Thank you!

        1. Carlos

          Kindly disregard my embarrassing previous mail – I was not using my head at all!
          I have now figured it out. I did not need a second script to run it in a scheduled task.
          Running the below command in the Arguments section of the scheduled task worked for me, plus I also got the report emailed:

          Powershell -executionpolicy bypass -file C:tempMailboxReportGet-MailboxReport.ps1 -All -SendEmail

          Again thank you very much Paul!!

  65. Tom

    I am running from my local Windows 7 machine with RSAT installed. I remotely connect PS to one of our mail servers. I am able to run other scripts with no issues. But when I run .get-mailboxreport.ps1 -database “database A” it immediately comes back to a prompt. There is no error. No file is created. I am not sure what I am doing wrong here, hopefully you can tell me how to correct it. -Thanks

  66. David UK

    Hi Paul,

    Thanks for taking the time to create such a useful and widely used script.

    However, each time I run the script it doesn’t output any information in the ADUser columns (Account Enabled and Account Expires). Everything else is as expected. Is it me doing something wrong or do I need to modify the script to work?

    Thanks,

      Paul Cunningham

      That part relies on the Active Directory PowerShell module. From the same server or workstation that you’re running the script from, can you run AD cmdlets like Get-ADUser without error?

  67. Kirk

    I need to keep stats on mailboxes relative to their retention policy. I have a one year retention policy, excluding contacts, calendar, tasks and drafts. I want to report on any mailboxes that have data beyond the retention policy. Can just get the mailbox size of data over a year, that would include data in the excluded folders.

    I believe I can use EWS to do this but have not found how to exclude the specific folders.

      That usually means you’ve downloaded a bunch of HTML from Github instead of just the PowerShell code. You might find it easier to use the TechNet Script Gallery link instead.

    Hi Paul,

    Brilliant script and has worked perfectly.

    Just wondering if there was an easy way of adding the mailbox quota size as a heading on the top 10 email form?

  72. Paul

    Hi Paul,

    Thank you for this great script. Just wanted to know if it includes as well a way to detect if a userA had tried accessing a userB mailbox?
    Do you think that this is something that could be integrated by any chance?

    Regards,

    Paul

  73. Anthony I.

    Thanks for providing this great tool. I wanted ask if there other parameters that could be used to pull stats for mailboxes within a child domain? We have a root domain that contains several child domains. Is there a way for your script to just search for users of single domain?

    Thank you.

      Paul Cunningham

      The script doesn’t include a parameter for that, but you could easily modify it to suit your needs. Just look for the line with the Get-Mailbox cmdlet and modify that to what you want.

      1. Cam

        Hi Paul,

        Do you have the exact command for this? I tried this –

        Get-Mailbox -resultsize unlimited | Select-Object displayname -expandproperty emailaddresses| Where-Object {$_.smtpaddress -like “mydomainname.com.au*”} | -IgnoreDefaultScope

        But It comes back with no results, but when I run it independently, it shows the mailboxes I am looking for..

  74. Mike Williams

    Is there any way to add the retention policy applied in the output of this script and the mailbox features that are enabled?

  75. Antoni

    Hi Paul,

    We are running Ms. Exchange 2007, and running more user with big size attachment when sending email via outlook and seamonkey, and the user mailbox is always full.

    And we alwayas delete the user mailbox that get full, and re-create the user mailbox, and here we need help, how to reduce or remove the full mailbox without to remove the user mailbox ?

    Thank you.

      Deleting and recreating a mailbox just because the mailbox was “full” (which I assume you mean it has reached its mailbox quota) seems like overkill to me. The user could just delete some unwanted mail.

  76. Robert Evans

    Ok guys what am I missing here? I have Exchange 2013cu8 running on Server 2012r2. When I try to run the script I that the output displayed below. But if I run this on an Exchange 2013cu10 on Server 2012 not r2 it runs fine. Is this because of r2 or am I missing something. Thanks in advance.

      Sounds like you’ve downloaded a bunch of HTML and not just the script.

      1. Bob Evans

        No if I copy that same file to the 2012 server it runs fine but on the 2012r2 server it does not.

          Paul Cunningham

          I can’t see your file so I’ve no way to know for sure. But the error you’ve provided has strings like “form accept-charset=”UTF-8″” that don’t exist in the PowerShell script. Which makes it sound to me like you’ve gone to Github and done right-click -> download on the script’s file name.

          If you do that it downloads a bunch of HTML that isn’t part of the script (if you open it in an editor and see DOCTYPE HTML at the start then that will confirm my suspicion).

          So there’s not much else I can suggest without being able to see your system, other than going back to Github and making sure it’s downloaded properly, or download it from TechNet instead.

        Server 2012R2 with Exchange 2010

    1. Wayne

      This is because Windows 2012 runs Powershell 4.0 natively. When it tries to import the AD cmdlets, they are not compatible since the script is looking for 2.0. We had to run it from an Exchange shell on a Windows 7 workstation, not the server itself which was 2012.

    This is all it outputs anytime I run that script, also it won’t output to a file. Beginning to suspect something wrong with PS? However, other Exchange PS commands do work.

      Paul Cunningham

      Maybe the script is getting blocked. It’s failing to connect to your Exchange server…. try simply copy/pasting the script contents into a new file and save that as a PS script and run that?

      1. Marc Schnitman

        I have done that too. Odd thing is that the first attempt fails, but second attempt succeeds. I had to “allow” the script as seen in the output. I have also tried copy/paste into a new file: A) directly from GitHub and B) from the actual download – same result regardless.

  82. Marc Schnitman

    For whatever reason, the script is only returning a report, on the screen, for one user. And it always reports that one, and only one user.

    Q1 = How do I get this to report for all users, I have used the “-all” option
    Q2 = How do I get it to either e-mail me the CSV or create a CSV to a provided path. I have used both the e-mail and filename options, neither work.

      Mailboxes have an attribute of “WhenCreated” that has that info.

      1. James Slack

        The field you are looking for is called “WhenMailboxCreated”.

        If you just need to know when all the mailboxes were created, you could do a simple command like get-mailbox | select Name,WhenMailboxCreated

        1. Chris

          Thanks James for your reply but this command does not support Company, Department Office fields.

      2. Chris

        Thanks Paul for your reply..

        What I need to do is Get-mailbox | Select-Object DisplayName, PrimarySmtpAddress, Company, Department, Office, WhenCreated | export-csv “c:outputfilename.csv”

        This command give me a blank in the “company, department & office” fields

        could you help pls

    Hi,

    Can you tell me how you schedule this powershell script in schdeule task to get the report in email on weekly basis. I’m specifically looking for what arguments i need to enter in the schedule task to get weekly email.

    I am trying to run the script on an Exchange server 2013 Windows Server2102 an continue to get Import-Module : The specified module ‘ActiveDirectory’ was not loaded because no valid module file was found in any

    Can you help me out. This usually means that this is the wrong version of the script file

        “Install the ActiveDirectory module for PowerShell.”

        I raise you: “Mention this in the requirements for the script to run successfully” …

        The Exchange servers in my organization don’t have the AD module installed presumably for a reason, so I cannot run the script at all. Bummer.

          You could install the Exchange management tools and the AD module on your workstation, or a management server, and run it from there.

    Disregard my last Paul. All working great. Its Friday and im an idiot 🙁
    Thanks for your quick response.

    No mods and im confident its not the script. Rather the way I am calling it.
    I was using quotes around the script name but not this time.
    I run this
    .Get-MailboxReport.ps1 -All

    And get this:
    Missing expression after unary operator ‘–‘

    Thank you for your script Paul. Im having rouble running it though and am new to this.
    error is “You must provide a value expression on the right-hand side of the ‘-‘ operator. Which I am doing of course. Its referencing the -All or -Server parameter.
    Its Exch 2010 and im running from the server. I get the same error for each of the valid parameters.

    This script works perfect and getting report in the email if i use commands. I need to some help to configure this script in schedule task. Can you provide the steps to schedule this script in schedule task to get this report in the email in weekly or monthly period.

  90. James Slack

    Just to clarify my above comment.

    If we could have a script that would look at a mailbox and say that 15000 items that are 1.2GB in size are over 2 years old in the given mailbox, that would tell us everything we need.

  91. James Slack

    Hi Paul,

    I am trying to work out how you would write a script, which you can run against users to see how much email (item count and file size) they have over a certain age.

    The reason I would like this would be to work out which users to enable to Exchange 2013 Archiving first and justify what space we will recover.

    I’m not sure I have seen a cmd that would cover this though. My guess would be that this can only be done with something horribly complicated like EWS, but maybe you could suggest something I could use to write this that I am missing?

    Thanks as always
    James

      1. James Slack

        Thanks Paul – I’ll take a look, that example is perfect.

      Exchange 2010 SP2 UR7
      Running on one of the Exchange Boxes so the Management Tools are installed.
      Script Unblocked and execution policy set to Unrestricted

      Also tried with a remote PS session from my Windows 8.1 machine, this appears to run the command but then crashes the window when it looks like its about to retrieve the result.

  97. Razi

    Thanks for your reply Paul, Yes the script is written to require a parameter but I want to know if there is way to run it without parameter, Since you are a developer of the script I am requesting you to let me know how to run it without param as I am using it in my application which does not accepts any parameter and the design of my application is such a complex one which cannot be changed. You help will be highly appreciated.

    The out put has 2 columns, Total Mailbox Size (Mb) and Mailbox Size (Mb). What is the difference between them, other than the numbers that are reported? Is the first number including white space and the second the actual mailbox size?

    how can i execute your script if my database mailbox name is Mailbox Database 1159192321.
    Its possible? or i must rename the name first?

      If the database name has spaces in it then you’ll need to enclose the name in quotes.

      .Get-MailboxReport.ps1 -Database “Mailbox Database 1159192321”

      This is one reason that I tend to keep my database names short and without any spaces in them, eg DB01, DB02…

      You can also try just running “Get-Mailbox -Database ” and see if that works, since that is all the script really does when you use the -Database option.

    Hi Paul,
    thanks for the script… I was looking for a similar tool and this seems to fill my needs.
    But I have a tough time running it.
    EMS gives me twice a strange error message and dies gracefully… 🙁

    Environment: Windows Serrver 2008 R2 SP1 + Exchange 2010
    The error, translated back to English, is something like:

    Can you please give some advice ?

    I modified this script by adding a parameter for CustomAttribute1. This allows me to get a report for customer even though they have multiple databases.

    I’ve noticed that even though I start the script in exactly the same way for each customer, the column Deleted Items Folder Size (Mb) is not present in every report. It seems to be consistent. If it is not present in one customer’s report, it never is present there.

    Any ideas why this might happen?

  118. JoeS

    Hi Paul,

    Any idea why I would get “Starting a command on remote server failed with the following error message : The WinRM client sent a request to the remote WS-Management service and was notified that the request size exceeded the configured MaxEnvelopeSize quota.”

    This only happens on some users. When this happens, the csv file will be missing info related to Title, Department, Office, OU.

      When I’ve seen the issue myself it has only been when EMS connects to a particular CAS. After the CAS is restarted (eg for patching) the issue goes away. I’ve never really gotten to the bottom of it. A workaround is to connect your EMS to a different CAS.

    Hi Paul,

    are there any command to export all shared mailboxes with size?
    Seems like Get-mailbox -RecipientTypeDetails sharedmailbox -Resultsize unlimited with parameter totalitemsize is not valid.
    Get-MailboxStatistics doesnt support receipienttype/type (so i can filter user or sharedmailbox) either,
    Kinda stuck in between!
    thanks!

      Get-Mailbox doesn’t return TotalItemSize, but Get-MailboxStatistics does. So the answer is to pipe the output from Get-Mailbox into Get-MailboxStatistics.

  121. Dhillan

    Paul – thanks for this wonderful script. I have used it over the past 2 years now on a number of deployments that i have done and clients are really appreciative of this.

    I however have been trying to run the same script on an Exchange 2013 deployment, the script runs fine except that I do not get information on the StorageLimitStatus. My understanding that there has been changes made to the store and Exchange Server 2013 Information Store does not cache the values of mailbox quotas.

    I am not the best at powershell and have seen that there are ways to get around this but have not been successful. Is there a chance that you will update this script so that it would work on Exchange 2013?

    1. Avatar photo
      Paul Cunningham

      You’re right, that status is no longer reported in Exchange 2013. To get the answer you’d need to compare the mailbox size value to the quota (if any is set) on the mailbox (which can be set on the mailbox or the mailbox database).

  122. Allen

    I wonder if it is possible for this script to run for only the users with hidden mailboxes? I’ve tried altering the script and have had no success. I’m trying to find all of the hidden addresses with who has full and/or read permissions to the hidden addresses listed, but I could do the permissions part manually.

  123. Tim McCarty

    Paul – I made some additions / changes to your script – if you would like I would be happy to send it to you for your review / use.

    Thanks again for providing such a stellar script.

    In the interest of full disclosure – i will say that the changes I made do NOT improve the functionality (memory use, etc.) of the script – I mostly have it collecting more data – and added an option for quickly testing in new environments.

    Paul – thanks for this – I am wondering about running this script in very large environments. I am presently working in an environment with over 80,000 mailboxes and the script is taking a very long time to run (in excess of 4 hours) and the working set (RAM) after 4 hours is 7 GB. I am also seeing this error in the console ” Processing data for a remote command failed with the following error message: Objects cannot be added to a closed buffer. Make sure the buffer is open for Add and Insert operations to succeed. For more information, see the about_Remote_Troubleshooting Help topic.

    Anyway the point and my question – have you considered any improvements for the script when working with very large data sets and/or can you point me to any helpful resources for improving the script myself?

    Thank you for your time and attention!

      Paul Cunningham

      In a similarly sized environment (where I developed early versions of that script) I never ran it for the entire organization in one go because yes, it takes forever, and yes, it eats a huge amount of RAM.

      Instead I would run it using the -Server or -Database parameters to just get the specific info I needed.

      Perhaps there are more memory-efficient PowerShell techniques that could be used to handle very large scenarios like that but I haven’t looked into it.

  125. jay

    sorry – should have been clearer with what I was chasing above. i can get the user to where this is forwarding by putting in the following line:

    $userObj | Add-Member NoteProperty -Name “Forwarding Address” -Value $mb.ForwardingAddress

    but ideally I would like to have the actual email smtp address but I don’t know how to get it using the ForwardingSmtpAddress property (seems I need to get this from Get-Mailbox instead of Get-Mailboxstatistics??)

    Also, I can get all the smtp addresses by using:

    $emailaddresses = [string]::Join(“;”,($mb.EmailAddresses | Where-Object {$_.PrefixString -ceq “smtp”})

    which is fine but I’d ideally like to remove the smtp: part from the start of each email address. Maybe I’m just being picky on this one… Thanks.

    Thanks for the great script – works like a charm. Can you point me in the right direction to add two extra columns? I would like to add forwarding address & all other smtp addresses (maybe seperated by a colon or similar). I’ve managed to do this in my own script but it’s fairly primitve and ideally would like to intergrate into your script but I’m not sure how to go about this. Cheers

    Paul,

    Thank you for this great script. I am trying to tweak the powershell to get it to show me the StorageLimitStatus but cannot seem to get it to work. I have added Storage LimitStatus to the $stats list (Line 154) and added a new row like the others (Line 179). The heading shows up on my CSV, but I get no data. The two lines as I have them in my code are as follows:

    154: $stats = $mb | Get-MailboxStatistics | Select-Object TotalItemSize,TotalDeletedItemSize,ItemCount,LastLogonTime,LastLoggedOnUserAccount,StorageLimitStatus

    179: $userObj | Add-Member NoteProperty -Name “Limit Status” -Value $mb.StorageLimitStatus

    phenomenal script! I did, however, run into a weird thing. When I filtered the spreadsheet to display the archives of users it only showed one, versus at least 15-20 people’s archive on my Exchange 2010 SP3 server, Any clue as to why this could display wrong data?

      1. Dennis Hartmann

        Thanks Paul,

        I simply ran the -all condition to get as much info out of our Exchange environment as possible. We have 4 DBs, 3 with quota on mailbox size and one dedicated as the “Archive DB” with no quota. in addition what your script provides, I’d like to see how my archive DB is growing in size. So far, we only have company executives Archive enabled, fearing the DB would grow out of proportion if it were enabled for all users.

        Again, thanks Paul!

          I see. What you’re getting then is regular mailboxes that are sitting on your archive DB.

  137. Allen

    Todd,

    No difference. Here is an example of what I see in the EMS – the command seems to simply echo back but no CSV files or even errors or additional info is generated:
    PS C:scripts> “.get-mailboxdatabase -all”
    .get-mailboxdatabase -all
    PS C:scripts>

    1. Allen

      Typo – please excuse me. Here is the actual text from the screen ….

      PS C:scripts> “.get-mailboxreport -all”
      .get-mailboxreport -all
      PS C:scripts>

      Allen

    2. Todd Nelson

      One thing that I see is very curious. The name of the script referred to in this thread is “Get-MailboxReport.ps1”. Therefore, the command being run should be “.get-mailboxreport -all”. So, I feel this is probably a typo.

      If it is still not running for you, I cannot think of anything else but to make certain the file is unblocked from running and that the report output is being sent to a folder that isn’t set to read-only.

      I am running Exchange 2010 SP3 hosted on WS2008R2SP1 with PowerShell 2.0.

      When I run the command, this is what I see…

      Another thing I could recommend is to download the script again but to a new/different folder on your mailbox server and try to run again.

      1. Allen

        Todd,
        Thank you very much for all of your replies. Yes, there was a typo that you picked up. I’ve tried running:

        PS C:\> cd scripts
        PS C:scripts> .get-mailboxreport -all
        Collecting mailbox list
        Collecting report data
        No mailboxes were found matching that criteria.

        And tried running:

        PS C:scripts> “.get-mailboxreport -all”
        .get-mailboxreport -all

        And you see the results. Tried another download to another directory with the same results. Permissions are all fine. I am running Exchange 2010 SP1 rollup 8 on Windows Server 2008 R2 Datacenter with SP1 and powershell V1.

        Here’s what I see after a fresh download to the C:Tools directory (newly created directory with permissions rechecked):

        PS C:tools> get-executionpolicy
        Unrestricted
        PS C:tools> .get-mailboxreport -all

        Security warning
        Run only scripts that you trust. While scripts from the internet can be useful, this script can potentially harm your

        Interesting. Different info on the screen this time though.

        Database names in the DAG are DAGDB1 and DAGDB2. Calling them in the -database variable doesn’t change anything either.

          You need to run it in the Exchange Management Shell or at least a PowerShell window where you’ve loaded the Exchange snapin.

          If you just open plain PowerShell and run it then you get no results, as you’re seeing.

          The next version of the script will account for that and give a more useful error if the snapin can’t be loaded.

  138. Allen

    I’ve been successful a few months back in manually running your excellent script but tried again today and nothing happens. No errors but no CSV files appear. Command line looks like this:
    PS C:scripts>”.get-mailboxreport -all” or “.get-mailboxreport” are accepted without any feedback.
    I am running this on the active mailbox server against a DAG in Exchange 2010. I must be missing something really simple! Advice?

    1. Todd Nelson

      Allen,

      Does the account you are running the script with a member of the “Organization Management” group? I don’t feel the account needs Enterprise Admins membership but may since the script seems to query AD.

      Todd

      1. Allen

        My account is a domain admin and a member of the Exchange Organization Administrators. I can try adding myself to the Organization Management group to see if that makes any difference. Will update in a few. Thank you.

  139. Todd Nelson

    I LOVE THIS SCRIPT! I’ve been using it for a while and it helps me to identify “dead” mailboxes, their sizes, etc. However, I recently ran into an issue that I am unable to figure out.

    If I run the script against my lab environment (or most any other for that matter) with Exchange 2010 SP3, I receive information for all of the headers…

    “DisplayName”,”Title”,”Department”,”Office”,”Enabled”,”Expires”,”Last Mailbox Logon”,”Last Logon By”,”Item Size (KB)”,”Deleted Item Size (KB)”,”Items”,”Type”,”Server”,”Database”

    But, I ran into a situation where two of the headers do not show in the report. And these headers (and info) are quite important to determine our migration strategy. The two headers that do not show are…

    “Item Size (KB)”,”Deleted Item Size (KB)”

    I am running the same command and the same switches (using server name) but the results are different in this particular environment.

    Paul, any ideas why this might be occurring?

    Todd

    Hi Paul.

    First off, GREAT script!

    Is there a way to break down the stats by date range per mailbox? Example:
    Items 0-15 days, Size 0-15 days, Items 16-30 days, Size 16-30 days, etc.?

      Paul Cunningham

      I guess you could use EWS to analyse the mailbox contents but I imagine it would slow down the script enormously.

  142. Shane Bryan

    thanks Paul. what happened is i have a few scripts set to run automatically via task scheduler, i inadvertently deleted the task that run this one – which had all the parameters so it would run as intended.

    i was trying to run it manually, without those – sorry about that 🙂

    Cheers Shane.

  143. Justin

    This script is great, a real time saver. I do have one question. We have 2 MB servers that are in a DAG. When I run against one I only get about 1/4 of the mailboxes returned. I know they’re all on both as we flip back and forth on mount points when we need to to perform maintenance (and the DB sizes are the same on both). Any idea why only one would return full results and the other incomplete?

    Thanks!

    1. Avatar photo
      Paul Cunningham

      The -Server parameter for the script isn’t really suited to DAGs. That is probably because when I first wrote it there were no DAGs in the environment I was working in.

      The ServerName on a mailbox that is hosted on a DAG is misleading. I believe it gets stamped with the server name that the database was active on at the time the mailbox was created, but doesn’t update as active databases switchover.

      Have you modified the script or upgraded your version of PowerShell or something like that?

      Note also that some combinations of parameters can’t be used. Eg, you can’t use -Server and -Database together.

      1. Scott

        thanks for the quick reply.

        it ended up being UAC settings set too high.

        thanks!

    Had some trouble getting this to work. When you typed Get-M it autocompleted the rest for you, It did not do this for me, I tried typing out the whole command but kept getting an error that it could not find the script. I had to type out

    .Get-MailboxReport.ps1

    with the . in front before it would run. spent about 10mins before I figured that out…… Sure was much easier when you could open exchange 2003 and it told you how big the mailboxes where in a GUI.

    Good article though, thanks for the help.

    Hi Paul,

    I have modified your script to give information on online Archive if one is enabled. Insert my code in $userobj section:

    $userObj | Add-Member NoteProperty -Name “Database” -Value $mb.Database
    #========Online Archive code================
    if ($mb.ArchiveDatabase)
    {
    $astats=$mb | Get-MailboxStatistics -Archive
    $userObj | Add-Member NoteProperty -Name “Archive Item Size (Mb)” -Value $astats.TotalItemSize.Value.ToMB()
    $userObj | Add-Member NoteProperty -Name “Archive Deleted Item Size (Mb)” -Value $astats.TotalDeletedItemSize.Value.ToMB()
    $userObj | Add-Member NoteProperty -Name “Archive Items” -Value $astats.ItemCount
    $userObj | Add-Member NoteProperty -Name “Archive Server” -Value $astats.ServerName
    $userObj | Add-Member NoteProperty -Name “Archive Database” -Value $astats.Database
    } else {
    $userObj | Add-Member NoteProperty -Name “Archive Item Size (Mb)” -Value “”
    $userObj | Add-Member NoteProperty -Name “Archive Deleted Item Size (Mb)” -Value “”
    $userObj | Add-Member NoteProperty -Name “Archive Items” -Value “”
    $userObj | Add-Member NoteProperty -Name “Archive Server” -Value “”
    $userObj | Add-Member NoteProperty -Name “Archive Database” -Value “”
    }
    #=====Online Archive code ends==================

    Also to support non-latin characters in your report and to be able to open straight with MS Excel change your export command to
    #========New export code=================
    $report | Export-Csv -Path $reportfile -NoTypeInformation -delimiter “;” -encoding “utf8”
    #========New export code end=================

    Hey,

    Great script. I am trying to figure out how to get one more field added, all SMTP addresses (aliases) for all users. How can I accomplish this.

    I typically do the following:Get-Mailbox | Select DisplayName, Alias,PrimarySMTPAddress, @{Name=’EmailAddresses’;Expression={[string]::join(“;”, ($_.EmailAddresses))}}

    I am not sure how to integrate that here.

  152. Kelley

    I have customers who have multiple databases for their mailbox. Is there a way to alter the -database paremeter to analyze all databases that begin with a specific set of characters?

    1. Kelley

      I think I’ve found a way to resolve my issue. I added these lines in the appropriate places in the script:

      [Parameter(ParameterSetName=’CustomAttribute1′)] [String]$CustomAttribute1,

      if($CustomAttribute1){ $mailboxes = @(Get-Mailbox -Resultsize Unlimited | where {$_.CustomAttribute1 -eq $CustomAttribute1} ) }

      This allows me to report on a subset of my users regardless of what database their mailbox is in. It does take a while to gather the matching users before processing but if I schedule this and other variations to run at night it should not put a crunch on the server. I already run nightly scripts to set the proper value for CustomAttribute1 for users.

      This is a really nice script that is well documented and I truly appreciate it.

  153. Ken

    Thank you much and great work as always. Anyone know a way to add the Sent Items to the report? TotalSentItemSize to the Select-Object line and $userObj | Add-Member NoteProperty -Name “Sent Item Size (Mb)” -Value $stats.TotalSentItemSize.Value.ToMB() to the PS object. The script runs fine but does not output the Sent Items value.

    Thanks,

    Hey Paul. Great script outside of a couple minor suggestions.

    If the script requires a specific version of PowerShell; include the following:

    #requires -version 2
    write-host “Can only run on v2.”

    Also, it may be a better choice to use, “Set-ExecutionPolicy RemoteSigned” instead of “Set-ExecutionPolicy Unrestricted”

    Cheers

  159. Igor

    The script is perfect the only thing that would make it even better for me is to include the following: IssueWarningQuota, ProhibitSendQuota, ProhibitSendReceiveQuota. Any chance you could do it?

  160. Rolando Rodriguez

    Paul,

    I’m trying to run the script, however my databases have users from 3 seperate child domains. The report runs through for the local domain where the Exchange servers are hosted, but throws errors about not being found on the Domain Controller. I have a similar issue when I have to do exports and actually define the DC for the other child domain to pull an export. Any way this can be addressed in the script?

    1. Avatar photo
      Paul Cunningham

      At about line 130 in the script is the series of Get-Mailbox commands for the various all/server/database scenarios. You can modify those lines to specify a DC if you need to.

      Interesting that you’re having that problem at all. The script is designed to ignore default scope and search the entire forest, so it should find any mailbox regardless of child domains.

      1. Rolando Rodriguez

        Paul,
        Once it ran against the whole Server, it DID pull me back the info for the mailbox size and item count, but it didn’t pull back the AD info for the mailbox except mailbox user name. At the end, it did what I really needed, so THANK YOU!

    Thanks for the great script. I modified the Total Item Size and Deleted Item Size ToGB() because of the size of the mailboxes I am dealing with.

    $filetimestamp is appended to the csv file when it’s written.
    $datatimestamp is used in [$userObj | Add-Member NoteProperty -Name “Date” -Value $datatimestamp] and displays the date as “6/07/2012” inside the csv file

    Perfect! Thank you so much 🙂

      Yeah I just don’t see it in the original. Modifications are fine, people should certainly feel free to tweak these scripts to suit their needs.

      So what is the goal of that extra property you’re trying to set? Is it so your SQL import knows which day the stats apply to?

      1. Shane Bryan

        Hi Paul, yep at present I manually edit the csv file and replace all the 020712 date data with 02/07/2012 manually.

        it doesn’t take long, but the more i can automate the better 🙂

        Try this:

        $userObj | Add-Member NoteProperty -Name “Date” -Value $a

        You can use any variable name you want I’m just $a for the sake of example.

  184. Shane Bryan

    Hi Paul. I notice in the script that the variable $timestamp is used in 2 places?

    $timestamp = Get-Date -UFormat %dd%mm%yy
    $reportfile = “C:PSScriptsCopyMailboxReport-$timestamp.csv”

    this places the timestamp on the file name (which is invaluable)

    and also;

    $userObj | Add-Member NoteProperty -Name “Date” -Value $timestamp

    places the time stamp into the spreadsheet data itself, next to the user name, dept, mailbox size etc.

    in the csv file, the date is displayed as 060712 (when I run it today).

    is it possible, to have the date (in the data, not necessarily the file name – as it won’t like slashes) be in the 06/07/2012 format?

    that might require the creation of a second timestamp variable though just for the date inside the csv file?

    if i change the $timestamp variable to;

    $timestamp = Get-Date -UFormat %dd%mm%yy

    the date on the file, and in the data gets written as; 06d07m12y

    I don’t expect you to solve the worlds problems for us, but is there a link or something you can share that will educate me on how to achieve the date formatting I need?

        OOOh, YES, I have tested and it is working perfectly …. 🙂 Really Thanks

  188. Jon Schlatter

    Thank you, this script has been very helpful! I do have one question that on an issue I see when I use it.

    Each time I run it I see a number of errors saying the following. Please note the

    The operation could’nt be performed because object ” couldn’t be found on ”.
    + CategoryInfo :NotSpecified: (:) [Get-User], ManagementObjectNotFoundException
    +FullyQualifiedErrorID: : ,Microsoft.Exchange.Management.RecipentTasks.GetUser

    This happens to users that are in one specific domain (which I can query with no issues in AD Management). Would anyone have any ideas on what I can do to resolve this?

    1. Jon Schlatter

      Please disregard my previous post. I found the answer to my issue only moments later. I corrected the recipent scope and all is fine.

    Hi Bryan, thank you for your answer.
    I do not have a sql database but only a intranet webs erver where to publish the html report.
    I saw the codee like this:

    $style = “BODY{font-family: Arial; font-size: 10pt;}”
    $style = $style + “TABLE{border: 1px solid black; border-collapse: collapse;}”
    $style = $style + “TH{border: 1px solid black; background: #dddddd; padding: 5px; }”
    $style = $style + “TD{border: 1px solid black; padding: 5px; }”
    $style = $style + “”
    $message.Body = Get-ExchangeServer | Select-Object Name,ServerRole | ConvertTo-Html -Head $style

    Where can i put this code in your script to have the csv to html report file?

    I tried to insert in the following part of your script code but but I did not get the html table file:

    $reportcount = $report.count

    if ($reportcount -eq 0)
    {
    Write-Host -ForegroundColor Yellow “No mailboxes were found matching that criteria.”
    }
    else
    {
    #Output single mailbox report to console, otherwise output to CSV file
    if ($mailbox)
    {
    $report | Format-List
    }
    else
    {
    $report | Export-Csv -Path $reportfile -NoTypeInformation ???–> in this part?
    Write-Host -ForegroundColor White “Report written to $reportfile in current path.”
    Get-Item $reportfile ?? or in this part?
    }
    }

    Thank you so much for you help.

    David.

    David, do you have SQL reporting services available to you?

    We take the data from this script and it gets imported into a database for SQL reporting. It allows me to see weekly growth on mailboxes by department and user. I totally recommend that if you have the resources available to you. Perhaps that might be more useful than simply dumping it into a html file, using a database and reporting services will let you track growth, find the heaviest mail users – and if your company is so inclined, charge accordingly.

    Before I found this script we were going to spend a great deal of money on a reporting system that went through the Exchange server logs. This script coupled with SQL reporting has pretty negated that.

    Anyhoo, there IS a ConvertTO-HTML option you can use with PowerShell, this link may help.

    http://technet.microsoft.com/en-us/library/ff730936.aspx

      Hi Shane,

      how is this done ? I am quite interested in doing this. Could you or any one else shed some more light on it ?

      thanx.

      1. Shane Bryan

        Hi Ray. I use the script that Paul kindly created with just a couple of slight modifications. My copy of it is here; http://pastebin.com/yVyJdpxh

        One change was the folder where it dumps the csv file. The other change was appending the date to the filename of the csv file to create a history. I take no credit for this, from memory Paul helped me work that out also 🙂

        There is a scheduled task on our Exchange server that runs this script once a week. Another scheduled task then robocopies the csv file to a SQL server that’s running Reporting Services. We then convert the .csv file to a .xls file, cleaning some of the data up. This excel file is then fed into the reporting database and then displays in the report when that is run. I’d past an export of that, but there’s corporate information in it so here’s a snippet of it, with corporate info blurred out.

        http://img827.imageshack.us/img827/387/captureqzh.jpg

        The report can be filtered by date, department etc so the majority of the work here was in the quality of the report created by our appsdev person.

        It also drops down to show the users from each department and the size of their mailbox on those dates. It’s shows growth, but also shows when someones doing a mass delete in their mailbox (perhaps a pending resignation etc, so we make a note of this in case we have to restore it from tape at some point).

        So unfortunately my ability to help further is hindered by the fact that the majority of the awesomeness was done by our awesome report writer. They take the data dump from this file and turn it into something useful 🙂

    2. Ray

      Thanx a lot Shane.

      1. CRAZY IT guy

        Hi Shane,

        Can you please provide the code to import excel file to SQL reporting DB server

      2. Shane Bryan

        Hi CRAZY IT guy. It’s a standard INSERT

        First we edit the spreadsheet a bit by changing the date from 020712 to 02/07/2012 which is done manually, then our code to import it is;

        INSERT INTO [ExchangeReporting].[dbo].[MailboxReport]

        select *

        from [ExchangeReporting].[dbo].[MailboxReport-070512]

        Obviously things will change for your environment such as the database name etc, also the file name is changed for each import as well. I hope that helps.

  191. David

    Hi thank u a lot for your wonderfull script.
    I need to bublic it to may intranet site. How convert it in html formatted tablereport?

    Could u modify the script to add html export?

    I’m trying to modify it but I’m not able.

    Thank you very much.

  192. Animesh

    Have you ever considered using a txt or csv file as input? I am currently evaluating Petri’s script for the same and can’t specify an input file. After analyzing your script, I find my problem as it is. Can you suggest me a way where I can specify a TXT or CSV file as input for users?

    Thanks,
    Animesh

      Paul Cunningham

      The script has a -file parameter for using a txt file as the list of users to generate the report for. The txt file should contain the list of mailbox users in a format that would work with Get-Mailbox, so that could be alias, email address, display name, etc.

  193. Lumir

    It seems that code
    #This is an aged mailbox, so we want some extra details about the account
    $user = Get-User $mb
    isn’t exact
    better is
    $user = Get-User $mb.Alias

      Seems to be working okay for me (although that comment about aged mailboxes doesn’t seem right, must have slipped in from another script).

  194. Bjarni Kristjansson

    This is brilliant, thanks
    e.s. I changed the export command to $report | Export-Csv -encoding ‘unicode’ -Path $reportfile -NoTypeInformation – because here in Iceland we have alot of strange Icelandic characters like æ á þ ð ó and so on!
    Nice work.

    Kalvin, as HotFix says, you will only be able to run this script either from with in the Exchange Management Shell version of the PowerShell console on an exchange server or from a computer that has the Exchange Administration tools installed onto it.

    You can use the following command to load the Exchange Management tools in a script though, if that helps or you have problems fiding the Exchange console.

    function Load_Exchange_Tools {
    if (-not (Get-pssnapin | ? {$_.name -like ‘Microsoft.Exchange.Management.PowerShell.e2010’})) {
    Add-PSSnapin Microsoft.Exchange.Management.PowerShell.e2010
    }
    }

    If you don’t have access to the tools, or your permissions don’t allow access to Exchange, you won’t be able to run scripts like this though.

    Rgds, Shane.

  196. HotFix

    @Kalvin – it looks like you are running that script from within a regular PowerShell console. You either need to load the Exchange snap-ins into that console, or instead run the Exchange Management Shell version of the PowerShell console (preferably IMHO). The Exchange Management Shell is installed on any computer you install the Exchange Administration tools on.
    Happy hunting!

    1. Kalvin

      I am actually running it remotely and I am not in Exchange admin group. I have been given readonly access. Does that suffice or I need to do more?
      Thanks!

    Thank you – you have made my job about a milliontimes easier with this script…and such a simple thing it is too when you delve into it.

    Why I had not thought of doing this sort of thing myself before I will never guess…but today, yes today Paul, you have made a new friend for life!

    Once again, thank you mate!

  199. Michael Boback

    Awesome script. Can you add functionality to show whether Exchange Archiving is enabled and the Total Size and Total Items in the archive? So far it seems the best way to check if archiving is enabled is to use Get-Mailbox | Select-Object ArchiveDatabase. Someone please correct me if I am wrong though. A value of null means archiving is disabled. I added some lines to the script and this worked.

    When I tried to use Get-MailboxStatistics -Archive | Select-Object TotalItemSize,ItemCount this seems to work, but if the mailbox doesn’t have archiving enabled it throws out an error. I’m new to powershell scripting so I don’t know the best way to add this to the script so it’s handled gracefully.

    Thanks!

    Hi Paul,

    I have added one Ps1 file which is callinghaving one function. I’m able to run the function( ex: get-Mail….). All is well.
    Can you help me to know, how to remove the Ps1 file and the function Get-Mail… in my exchange server environment. I don’t want others to run this shell command, whenever i need the details, i ll run the script and get the data.
    Help me to remove the function and PS1 file in safe manner

      1. Rajkumar

        I followed this article to use get-databasestatistics function. I’m able to use this EMS shell command.

        http://www.mikepfeiffer.net/2010/03/exchange-2010-database-statistics-with-powershell/

        I want to remove the new Get-Databasestatistics command from my exchange environment. If I remove the ps1 file from the scripts folder, will this shell command get removed? or do i need to un register the script in someway…? Kindly advice

        Yes, if you delete a script file you won’t be able to run that script any more.

      Why on earth would you want to remove that cmdlet? You know you can restrict who can run what cmdlet, right?

  202. Peter Watson

    Many thanks for this script, saved me many hours and lots of fingernails!

  203. Dan

    If you are getting the “No mailboxes were found matching that criteria.” message, make sure you are running the script in the Exchange Management Shell, this fixed it for me on Exchange 2007 and 2010.

  204. Tim

    This could be helpful. Is it possible to have the script run against just “room mailboxes” ?

    1. BR Thurr

      Tim,

      Go to line 75, and add this line underneath:
      [Parameter(ParameterSetName=’room’)] [switch]$room,
      Go to line 139, and add this underneath:
      if($room) { $mailboxes = @(Get-Mailbox $mailbox -RecipientTypeDetails RoomMailbox ) }

      Save it and run it with the -room parameter. I tested this and it works.

      1. Tim

        Thanks BR – put doesnt the switch (-mailbox, -database -server, etc) specify where to pull the mailbox information from? Therefore using ‘-room’ switch it would have to be followed by the actual room ? I am trying to pull all rooms from a database or server.

        Unless I am missing something. Thanks again !

    2. Avatar photo
      Paul Cunningham

      The mailbox type us already included in the report, so you could just run it without modifications and use Excel to filter the data afterwards.

      Another way would be to generate the list of room mailboxes into a text file and use the -file parameter when running the script.

      Or, yet another way, make a copy of the script and call it say “Get-RoomMailboxReport.ps1” and as BR suggests above change all the Get-Mailbox commands to add the “-RecipientTypeDetails RoomMailbox” parameter.

  205. ShaunH

    I have added to following values to show the Storage quotas as well

    $userObj | Add-Member NoteProperty -Name “IssueWarningQuota” -Value $mb.IssueWarningQuota.Value.ToMB()
    $userObj | Add-Member NoteProperty -Name “ProhibitSendQuota” -Value $mb.ProhibitSendQuota.Value.ToMB()
    $userObj | Add-Member NoteProperty -Name “ProhibitSendReceiveQuota” -Value $mb.ProhibitSendReceiveQuota.Value.ToMB()

    1. BR Thurr

      I have added these as well:

      $userObj | Add-Member NoteProperty -Name “Primary SMTP Address” -Value $mb.PrimarySMTPAddress
      $userObj | Add-Member NoteProperty -Name “Forwarding Address” -Value $mb.ForwardingAddress
      $userObj | Add-Member NoteProperty -Name “Hidden From Address Lists” -Value $mb.HiddenFromAddressListsEnabled

      Make sure that in your “Select=-Object” line (154 in the latest version), that you add these attributes into your select statement. For example:

      $stats = $mb | Get-MailboxStatistics | Select-Object TotalItemSize,TotalDeletedItemSize,ItemCount,LastLogonTime,LastLoggedOnUserAccount,HiddenFromAddressListsEnabled,ForwardingAddress,PrimarySMTPAddress

    2. BKK-Mac

      Hi ShaunH,

      I have added those lines to get storage quota and if I run the script against 1 mailbox, I can see those values but when I run against a database, those values are missing from the export CSV file.

      I have also added the values of BR Thurr and they are present in the CSV

      Any idea?

      Thanks,
      Mac

      1. Driguez

        @BKK-Mac

        did you get this solved eventually? I`m also having this issue with the script. Can only display it for one user but not for all in Mb.

        1. NK

          The issue is the Value.ToMB() setting as when it encounters a mailbox which has no value set this is returned as “Unlimited” which can’t be converted to MB and it causes it to fail.

          I got round that by setting up a conditional statement to test if the quota returns a value and attached to a variable and then calling that variable

          $ProhibitSendReceiveQuota = if($mb.ProhibitSendReceiveQuota.value){$mb.ProhibitSendReceiveQuota.value.ToMB()} else {“unlimited”}
          $ProhibitSendQuota = if($mb.ProhibitSendQuota.value) {$mb.ProhibitSendQuota.value.ToMB()} else {“unlimited”}
          $IssueWarningQuota = if($mb.IssueWarningQuota.value) {$mb.IssueWarningQuota.value.ToMB()} else {“unlimited”}

          $userObj | Add-Member NoteProperty -Name “MBIssueWarning” -Value $IssueWarningQuota
          $userObj | Add-Member NoteProperty -Name “MBProhibitSend” -Value $ProhibitSendQuota
          $userObj | Add-Member NoteProperty -Name “MBProhibitSendReceive” -Value $ProhibitSendReceiveQuota

  206. ShaunH

    Hi Paul
    How can we use this script and add the User Mailbox Quota in , so that it also shows in the csv file

    Thanks for the great script Paul. I’ve removed a few of the objects I don’t need, and plan to schedule this to be exported to a SQL server so we can import the results into a database and report on mailbox growth per user.

    I’ve changed your script to remove the random number being added to the file name, but if you can give me some advice on how to alter the export location that would be fantastic as i’d like the file exported to a folder that will have everything in it xcopied to another location at set times.

    Eg: C:ExchangeReportExport

    Cheers from Aus, and thanks again Shane.

        Yep, also I’ve added a -filename parameter to the latest version (1.1) just uploaded in the last few minutes if you wanted to grab that. It has a few other minor fixes as well.

  213. HotFix

    FYI I wrote a similar in concept script to generate Exchange 2010 mailbox billing reports in Excel directly. While it is a slightly different focus than what you are doing (in that it grabs all customer mailboxes or specific OUs, not databases or servers), perhaps you could recycle the Execl logic in my script to dump your data directly into Excel spreadsheet where you have already pre-formatted the attributes the way you want (which we also had to do) and save yourself a step or two:
    http://gallery.technet.microsoft.com/Exchange-Mailbox-Billing-a33bcbec

    I hope it helps.

    thz a lot fr the script, very useful

  215. Allen J

    Great script, but I am seeing something odd when I use the -server parameter. The number of mailbox objects listed in the EMC is 2498, but when I use the -server parameter it only processes about 1400 or so, not the full 2498. To get around that for now, I am using a generated user.txt file and using the -file parameter. Any ideas why the difference ?

      Hi Tom,

      Navigate to the folder where you’ve saved the script file, then run it with:

      .Get-Mailboxreport.ps1

      You’ll need to supply one of the parameters for which type of report you want to run. You can see the help info by running:

      Get-Help .Get-MailboxReport.ps1

      Or watch the video above for a demonstration.

      Hope that helps.

    Nice report. I’d like to put it into a scheduled task for a weekly/monthly report that’s emailed to me. I’m wondering how to call upon the output file as it will change each time it’s ran.

    1. Avatar photo
      Paul Cunningham

      Hi Christa, probably two ways you could do that.

      1) Remove the file name randomization. So instead of

      $reportfile = “MailboxReport-$timestamp-$random.csv”

      have simply

      $reportfile = “MailboxReport.csv”

      2) The file name is stored as $reportfile, so if you’re adding email functionality to the script you can always reference the file name by that variable, no matter what the real name is.

    2. Avatar photo
      Paul Cunningham

      I’ve added a -filename optional parameter to the latest version (1.1) for those who wish to specify the file name instead of the randomly generated ones (actually I use -filename almost every time I run it now :))

    Hello Paul,

    Thanks again för sharing your script. Works great, I just have a question… How can I do to find the right character in the csv file .. I m having in my exchange swedish names with those: å,ä,ö.

    Is it a parameter to add ?

      1. Kbart2000

        When Im having a look at the csv file after I ran the script,
        If for example the name of the user is Åsa Bergström, the result in the csv file is ?sa Bergstr?m

        Its not the right character, I would like to get on my csv file the swedish characters like : the å the ä and the Ö instead of “?”

        Hope I m more clear now? 🙂

        1. David

          I know this is years old, but it came up high when I googled for the same problem…

      Yep, little bug I need to work on there. If you have a multi-domain forest you’d just need to put your management shell session into viewentireforest $true mode to see all the mailboxes in the report.

      Or if you’re a single domain forest it doesn’t matter, script will work as you’ve modified it 🙂

    Hi Paul,

    Great report for Migrations. As I need the Alias to perform the migration, I have added this in the first column:

      Ah yep, see comment above. Try removing -ignoredefaultscope from the line:

      “if($file) { $mailboxes = @(Get-Content $file | Get-Mailbox -resultsize unlimited -IgnoreDefaultScope) }”

      I’ll add it to my bug list.

    I am trying to run this script using the -database or -file parameter and it’s generating a blank csv file. The csv file generated is of 0 bytes.

      That will happen if no mailbox info could be retrieved.

      For -database make sure you’re supplying a value that would work if you ran “Get-Mailbox -database “.

      For -file try removing the -ignoredefaultscope switch from the script line

      “if($file) { $mailboxes = @(Get-Content $file | Get-Mailbox -resultsize unlimited -IgnoreDefaultScope) }”

      I’ve added some script logic so that instead of creating a 0kb file it will instead show a warning that no mailboxes were found matching the criteria given.

    Great script! I removed a few of the output fields (we only have one mail server and one mail database, so those fields weren’t meaningful for us). At the moment I am trying to sort the resulting csv file via the script to put the mailboxes in order largest to smallest. Could use some help getting this to work.

    Once I’ve got that figured out, this script is going to save me a ton of time. I’ve got it running as a schedlued task on my exchange server and emailing me the resulting csv on the first of every month.

      In the last Else block try adding a Sort-Object to the $report | Export-CSV line like this:

      $report | Sort-Object “Size (Mb)” -Desc | Export-Csv -Path $reportfile -NoTypeInformation

      May also need to right-click the downloaded file, and in properties unblock it.

      Which version of Exchange?

      Try supplying the -database value as “serverstoragegroupdatabase” if you’re running Ex2007.

    Excellent script! Thanks for the work and the updates. I know that this will be used much by myself and the consultants I work with.

    Thanks again

      Hi Josh, it is written for PowerShell v2.0. Try running:

      $host

      …to see which version you’ve got. If you’re on version1.0 you can try and edit the script to remove all that help info at the start, and see if that works, but I haven’t specifically tested it on v1.0 to check for any other issues.

    hi

    good work paul, thanks for sharing,

  232. Chris

    Hi Paul,

    That script very useful, very well documented as well. I’ll try to improve it adding if the user has mailbox default storage limits.

    Thanks for sharing!

      Not with this script, but perhaps with a script that utilizes Exchange Web Services.

      1. Edward

        thank Paul

        if you have time to point me in a direction of how to write that script…that would be great.

        this one is really good too.

        I haven’t done any EWS script development yet, so I don’t have anything to offer you right now. Although you’re not the first person to ask me for a script like that, so I think its time I started to get into it 🙂

        But in the meantime, to learn about using EWS the first place I’d go to is Glen Scales’ blog here:

    Script has had a major overhaul and re-release, so much so that I’m just going to call this new one V1.0 🙂

    Hi Paul,

    Can u make this script work with server parameter? So it can list all the mailboxes from the server at once.

    Thanks,
    Sorin.

      Sure thing. Actually I’m already working on that, will post an updated when I’ve got it finished.

      1. Sorin

        I’ve managed to do it by myself 🙂 and now works with server parameter.
        I modified your script and it works perfect.

        Many thanks Paul,
        Sorin.

    This is Awsome. I tried it and works smoothly. Before using this scripte i used to get the results manually by just entering the commands every time.

    I have one query about the text file that we need to create for getting the results for particular users. which fileds should i enter in the text file.

    Thanks

      Display name, alias, or UPN should work. Take your pick. I usually just use display name.

        Hi Paul,

        I have one query on quota limit set as a default on those mailboxes where the actual mailbox quota limit value need to fetch from database. for example, If the MBProhibitSendReceive quota set on database is 1GB, mailboxes related to this database should show the report as 1GB ,in fact we are getting the report as unlimited. So i need a powershell command for the mailboxes, where it shows actual quota limit set on database along with other attributes of mailboxes. and one more thing on the same list, some mailboxes quota size not set as default value, it should fetch the exact value on same report. Hope you could understand my query. Please do the needful, would be a grateful to you. Thanks in advance
