The Exchange Management Shell, powered by PowerShell, makes it easy to collect size information for the mailboxes in an Exchange 2010 organization.

For example, to list the sizes of all mailboxes on a particular database we can use this command.

[PS] C:\>Get-Mailbox -Database MB-HO-01 | Get-MailboxStatistics | ft displayname,totaldeleteditemsize,totalitemsize

DisplayName      TotalDeletedItemSize    TotalItemSize
-----------      --------------------    -------------
Administrator    0 B (0 bytes)           85.42 KB (87,468 bytes)
Alan Reid        80.08 KB (82,000 bytes) 30.9 MB (32,400,667 bytes)
Alex Heyne       12.35 KB (12,644 bytes) 8.734 MB (9,158,159 bytes)
Aisha Bhari      0 B (0 bytes)           190.4 KB (194,983 bytes)
Aleisha Harrison 0 B (0 bytes)           142.4 KB (145,797 bytes)

If we wanted to know the total size of all of those mailboxes we could output the data to CSV file, import it into Excel, and use formulas to get the results. However that is time-consuming if all you are after is a quick answer.

So instead we can use the Measure-Object command in PowerShell to get the answers we’re looking for. However if we try to use it with the data shown above we’ll get this error.

Measure-Object : Input object "79.95 KB (81,870 bytes)" is not numeric.

So first we need to convert the data into numeric form.

For example, to see the sum, average, minimum and maximum size of the “total item size” for the mailboxes above we run this command.

[PS] C:\>Get-Mailbox -Database MB-HO-01 | Get-MailboxStatistics | %{$_.TotalItemSize.Value.ToMB()} | Measure-Object -sum
 -average -max -min

Count    : 5
Average  : 7.6
Sum      : 38
Maximum  : 30
Minimum  : 0
Property :

    I’m trying to figure out a way to run a script to only show room mailboxes that have a full mailbox I can do this on all users how can I limit this to just room mailboxes.

    #Add Exchange Module
    Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010
    Add-PSSnapin Microsoft.Exchange.Management.Powershell.Support

    #Declare Arrays
    $Mailboxes=$null
    $Mailboxes=@()

    Get-MailboxDatabase | Get-MailboxStatistics | Where-Object {$_.StorageLimitStatus -match ‘IssueWarning|ProhibitSend|MailboxDisabled’} |% {$Mailboxes += ($_)}

    $email = @{
    From = “you@yourdomain.com”
    To = “you@yourdomain.com”
    CC = “you@yourdomain.com”
    Subject = “Maiboxes with warnings or full.”
    SMTPServer = “mail.yourdomain.com”
    Body = ($mailboxes |out-string)
    }

    send-mailmessage @email

    Hi,
    In our company we have country specific mail domains. for example @companyname.no, @companyname.se e.t.c

    Is it possible to get info on how much for example @companyname.no users have taken space in total. We have exchange 2010

  4. Chris

    Hi,

    Thank you for this post. I am trying to accomplish the same thing but for ProhibitSendQuota but not having much luck.

    Get-Mailbox -Database MAILBOX-Z | %{$_.ProhibitSendQuota.Value.ToMB()} | Measure-Object -sum -average -max -min
    ForEach-Object : You cannot call a method on a null-valued expression.
    At line:1 char:36
    + Get-Mailbox -Database MAILBOX-Z | % <<<< {$_.ProhibitSendQuota.Value.ToMB()} | Measure-Object -sum -average -max -min
    + CategoryInfo : InvalidOperation: (ToMB:String) [ForEach-Object], RuntimeException
    + FullyQualifiedErrorId : InvokeMethodOnNull,Microsoft.PowerShell.Commands.ForEachObjectCommand

    I will need to get the total size of all mailboxes as well as ProhibitSendQuota for several databases so if they can be combined into one command that would be awesome. Tried several different ways of doing it but my attempts so far have been unsuccessful.

    Thanks!

      1. Chris

        Hi Paul,

        Thanks for that script I had not seen it before. I used it to generate reports on our 3 MDBs and get the information I was seeking. I had to do all of the calculations through Excel though which I was trying to avoid(and what originally led me to this post).

        We wanted to know the sum of the ProhibitSendQuota for all mailboxes as we are looking at storage upgrade options currently. It would be nice to know how to do this without Excel directly in powershell if the need ever arises again.

        Thanks

  5. TS79

    Thanks for the article.

    Others new to Powershell may appreciate knowing that in this command “%” is an alias for “foreach-object”. Knowing this helps to understand the command.

  6. Nick

    Fair point, and apologies.

    Which leads to the question of how to use these inside the ISE after importing the exchange cmdlets though import-pssession ??

  7. Nick

    Great article.

    Does not work remotely, only on the server, so essentially useless for a reporting from your desktop perspective, but great for those who work directly on the console of an exchange server …

  8. Mark Robinson

    This was a very helpful command and many thanks for publishing the article!

    Regards,

    Mark

      At the end of your command, add the following: ” | ft DisplayName Total,TotalItemSize”

  11. Henri

    Hi All,

    I’m looking for an PS script to export the size from the trash/recycle bin folder of all user mailboxes in our organisation.

    Could some one help a little?

  12. Shruti

    Hi Hector,

    Use ” | export-csv d:xxxx.csv” at the of the command.

  13. Shruti

    Please tell me how can i collect information about all the Conference rooms in my evviroment whether they have Auto Accept enabled or not?

  14. Hector Fonseca

    Hi Paul.
    Excelent Post. So, How I can export the report to csv file?.

  15. Frank

    Is it possible to get this information but instead of seeing the display name, see the email address of the FQDN or something similar?

    I’m setting up a hosted exchange and i will have multiple DisplayNames that are the same.

    How would I add a line to gather the users extension in exchange unified messaging?

  17. Jeff

    Out of laziness, can I change the parameter to show measurement in MB?

  18. Joe Olivarez

    You’re initially selecting totaldeleteditemsize and totalitemsize, but in the final command you’re only calculating totalitemsize. Can you explain?

  19. Joakim Razafimanantsa

    Very helpful, but how can I do if I want the total size of AvailableNewMailboxSpace on all DB?
    Thank you

    1. Lydon

      Just change the scope of the Get-Mailbox to wildcard:

      Get-Mailbox ** | Get-MailboxStatistics | %{$_.TotalItemSize.Value.ToMB()} | Measure-Object -sum -average -max -min

    2. cbailey

      get-mailboxdatabase | Get-Mailbox | Get-MailboxStatistics | select TotalItemSize | %{$_.TotalItemSize.Value.ToGB()} | Measure-Object -sum -Average -Maximum -Minimum

  20. Eero

    Is it possible to get same information about Archive Mailboxes?
