How many times each day do you get asked, “Is there a problem with the Exchange server?

If you’re like me then you get asked this question at least once per day. Of course there usually isn’t anything wrong with our Exchange servers 😉 but once the question has been asked then you have no choice but to investigate and confirm that everything is okay.

In this article I’m going to demonstrate how you can quickly check the health of your Exchange Server 2010 mailbox servers, and share a script with you that can help to speed up this task.

Note: a better version of this script is now available here.

Exchange Server 2010 has a series of PowerShell cmdlets that make it easy to do a health check of mailbox servers. For example, we can:

That’s quite a few cmdlets to run, especially if we’ve got more than one mailbox server in the organization. And of course each of those cmdlets needs to run and show you output that you need to interpret.

I like to make life a bit easier and use PowerShell scripts to speed up these types of tasks. So naturally I put together a script for performing all of the above tests (and a few more) on my mailbox servers and display a nice simple colour-coded output so that I can tell at a glance whether there might be a problem.

This isn’t designed to do a diagnosis of any problems, it just checks the fundamentals and gives me a simple pass/fail and a few other indicators that I can then troubleshoot further if necessary.

Note: a better version of this script is now available here.

Extract Test-MailboxServer.ps1 from the Zip file and run it in your Exchange Management Shell to see output such as this:

    Hey Paul,

    is there away to get the up-time in days and not hours? and if yes what would i add to the existing script.

    just like everyone here this script is GREAT! i just need to add this one thing for my Boss.

  2. avinash thakur

    i have changed the SMTP setting but still mails not getting triggred. Do i have to make any other changes in script.

    Hello Paul Cunningham

    Great script, Thanks for sharing, email not received, how to solve this ?

    Awaiting for your reply, Please do the needful

    Thanks again

    Hi Paul.
    Thanks again for another great article.

    In an environment where all databases in the DAG are mounted on a single DAG member would test-mailflow always give *Failure*
    Does it have to be able to send between mailboxes on separate servers to succeed?

    1. Avatar photo
      Paul Cunningham

      Yep, if I recall correctly if there’s no active databases on a server then the mail flow test will fail. I thought I had accounted for that and replaced the failure with an “n/a”. Are you using the latest version of Test-ExchangeServerHealth.ps1 from TechNet/Github?

      1. Andy Cordiner

        That’s great thanks. No, was just curious, as noticed that running the individual command always gave a *Failure* and was concerned that there was an issue somewhere.

        Really appreciate the response.
        Thanks again

    Hey Paul, this works perfectly. Thanks a lot !!

    On the public folders part, I had used the wrong word “decommissioned”, it was actually never in there. But the PFDB was there which has been dismounted recently. Please let me know if it still may cause us some issues leaving it in dismounted state in long run if we never had or plan to have public folders.

    Thanks a ton.

      “…it was actually never in there. But the PFDB was there…”

      Now I’m confused. Either the public folder database exists or it doesn’t.

      If it exists and you want to decommission it completely, don’t just leave it dismounted.

  7. Poulomi Ghosh

    Hi Paul,

    In our environment, since Public Folders have been decommissioned, we have dismounted the public folder database. Is there a way we can remove the alert for public folder database dismounted on this script?
    I have tried adding it to the ignore.txt file but that does not help.

    Kindly suggest.


    1. Avatar photo
      Paul Cunningham

      You could take the Get-PublicFolderDatabase line out of the script.

      But I would suggest to you that dismounting the PF database is not the same as properly removing public folders from your organization. Leaving it in that state is likely to cause you issues in the long term.

    Hi Sir,

    I was successful in installing exchange server 2013 sp1 on windows server 2012r2.After that i restarted my server and entered administrator credentials in the eac ,i am getting http error : 500 internal server error. and nothing is displayed on the page.

  9. Bill - NCC

    Brill little script, well not so little, helped fix some minor issues on the service.

    I need to schedule this script so it sends a report to another team, I know there is something I can do so it automatically sends the report but I cannot find the right bit. Any chance of sending me the code.

    Again excellent script.

  10. Lynn

    Greate Article. Paul. It helps.

  11. sam

    HI Paul, great script thank you. one issue though,

    The script can not send email notifications when a vital service like the transport service is off if the smtp settings used are for the internal server and the environment has only one server, how can the smtp setting be changed to accommodate external smtp settings like for google that may require authentication.

    thank you.

    HI Paul,

    I have just one server (mbx, hub and cas) and i’m getting this error:

    Add-Member : Cannot bind argument to parameter ‘name’ because it is null.

    Note: I,m running it on the same server where exchange 2010 is installed (windows 2008 r1)

    Any idea?

      Run the script with the -Log switch and then email me the log file to paul at and I can take a closer look. If possible attach one of the report emails as well so I can see the HTML results too.

  13. Roshan

    Hi Mate

    Thanks for the script!!!

    Have a good day.


  14. Brian

    i noticed that once the script finds a mail server with a high copy/replay count (like a lagged database copy server), all the remaining servers after that are also shown in red, even though they do not have this issue. I don’t believe that variable is being reset in your loop through the server list 🙂

    Another issue, when i pass a server name at the command line instead of letting it run through all of our servers, the mail flow test fails with:

    Mail flow test: Skip, no active mailbox databases
    Cannot bind argument to parameter ‘Server’ because it is null.

    Could you please suggest

    Thanks in advance

    My Exchange 2013 was working pretty well. After I deployed Sharepoint 2013, exchange got broken. First it was Port issue. I changed sharepoint’s. Now Exchange PowerShell Connects without a problem. running your script, it only shows dismounted mailbox failure and not checking mounted one. Running Test-MailFlow, It shows Failure. I’m talking general? I know, but any suggestion?

      Paul Cunningham

      You’ve installed Sharepoint on the Exchange server? I don’t recommend you do that. I’ve never tried it myself, so I have no idea what exactly it will break and how to work around it.

  18. Anna

    Thanks for a great script.

  19. CMRamos

    I like the script, BUT it does not properly reflect DAG health. As noted below, your script shows everything Passed, but when we ran Test-ReplicationHealth the QuorumGroup check failed with an error on the DAG. Something to include in a future revision is Replication Health.

    Hi Paul

    Also we daily running command to get the item count for journal mailbox

    get-mailboxstatistics -identity “Journal Mailbox Name” | select itemcount

    Can be include in this script? It would be great full if you add the above command in the scripts and relase.

    also as my previous request, The result should be goes to email via HTML fomat or it can be same result as in the on screen but it shd be send the email to exchnage admin
    so that we can schdeule this script in task and runs daily in the morning ,and all our exchange admins get the result via Email , instead of running the script manually

    I hope you understood our request.

  25. Ramki

    Hi Paul

    Is there anyway to send the result in HTML formatl via Email as Health Check Report

  26. Robert

    Hi Paul,

    great job. Big thx for the script. When can we expect a test script for the other exchange roles 🙂

  27. Max

    Great script. Thanks a lot.


  28. Oscar Pedroza

    Tks Paul…

  29. Oscar Pedroza

    Tks Paul, its a great job…

    One question do you have any script to check the performance of Exchange Server 2010 on and typically installation method.

    Best regards,

  30. Mark

    Thanks for the script. Looking forward for your next version. Sending an email alert to admin in the event of “RED” result would be nice.

  31. Tom G

    I figured it out. I had to include . in front of the command. Why?

  32. Tom G

    I don’t want to sound like a goober but when I try to run the script I get the following error:

    The term ‘Test-MailboxServer.ps1’ is not recognized as the name of a cmdlet, function, script file……….

    What am I doing wrong?

  33. DavidDC

    First of all, thanks for the script. is great.

    when I try to export the script output to a file, it is empty. Do You know the reason?

    I use this command:
    C: Scripts>. Test-MailboxServer.ps1 | ConvertTo-Html | Set-Content C: Scripts Logs Test-MailboxServer.html

    Sorry if my question is a bit silly

    Thanks for everything

    1. Avatar photo
      Paul Cunningham

      Not silly, the script is a bit lazy and just uses Write-Host to output to console. It wasn’t originally written with nicely formatted reports in mind 🙂

      I’ll be updating it with proper PS objects and such so that HTML output is a possiblity, among other planned improvements.

      1. DavidDC

        Thanks for your time.
        I’m testing with the command Start-Transcript-path C: Scripts Logs Test-MailboxServer.csv at the beginning of the script and Stop-Transcript to end.

        It seems to work fine. Now I just send it by email.

        Thanks for everything.

  34. Pol

    Thanks for this great script, very useful indeed!
    Could you add:
    1. Test-OutlookConnectivity (Protocol:TCP and HTTP)
    2. Test-SmtpConnectivity
    3 .Test-replicationhealth
    4. Queue reporting (Get-TransportServer | Get-Queue)

    it will be the best choice for any Exchange admin since it is a perfect combination of functionality and beauty.
    Thanks again for your great work !

      Sure thing, I’m working on a script to health check all the server roles in the org.

  35. Mike Koch

    Hi Paul,

    Great script, but I found one small bug.

    On line 254:

    $IsDAG = Get-MailboxServer $

    generates an error when a single server name is supplied as an argument on the command line, because it’s just a string instead of an exchange server object. When no argument is supplied, you do a Get-ExchangeServer to retrieve all of the servers, but when an argument is supplied, you’re not doing anything with it.

    Change line 56 from:

    $mbservers = @($server)

    to this:

    $mbservers = @(Get-Exchangeserver $server)

    and that will fix it right up.

    Thanks again,

  36. Joe

    Great Script – ran perfectly. I think I’ll tweak it and add the email functionality.
    Once again another great article.

        Paul Cunningham

        Hi Ram, sorry for the delay. I get that same problem if I try to run the script for a server that doesn’t exist. I guess that means the ping fails and the script is not handling that properly.

        So it could be that in your case the ping is failing too, perhaps due to a firewall? Can you ping the servers normally from the computer that you’re running the script on?

      3. Avatar photo

        Ram, I’ve updated the script to V1.1 with better handling of failed ping scenarios. Please try the new version and let me know how you go.

    This server does have a recovery database on it. Is that the cause of the error?

      Hi Kevin, I’ve put some RDBs in my test lab and can’t seem to reproduce the error you’re getting. Could you please try downloading the new version of the script and trying again?

      Also, when you’re running the script are you running it on the server that only has an RDB on it, or do you see the error when you run the script on another server or on your own workstation?

      1. Kevin

        Hi Paul,

        I’ll download the latest build and try it later.


  44. Chris Brown

    Hi Paul,

    Cool script, I’ll definitely be keeping it on hand.

    Just one quick note on using $nul as opposed to $null: $nul is settable like any other variable, $null is and always will be null.

    If someone has, for whatever reason, set $nul to a value, this could play havoc with some scripts.



  45. Kevin

    Hi Paul,

    I just remembered that there is one active database on that server. There are no copies of the database anywhere. This is the error message I get for that server.

    Hi Paul,

    Great script. Thanks for sharing. It works great on all the mailbox servers in my DAG except for a server that I have that only holds passive database copies. On that server the mail flow test fails with an unable to open message store. Not a big deal, I was just wondering if you knew why.

    Thanks again.

      Makes sense if there are no active databases on that DAG member then it can’t perform that test. I’ll update the script to skip that test when there are no active DBs.

          But we have more than 30+ DAG’s available on our environment, in that we need to monitor only one DAG. Rest of the DAG’s we need to ignore it.
