The Test-MAPIConnectivity PowerShell cmdlet will test the availability and latency of your mailbox databases and help you to troubleshoot issues with mailbox access.
Running Test-MAPIConnectivity on an Exchange 2013 Mailbox server will test the active mailbox databases on that server.
[PS] C:\>Test-MAPIConnectivity MailboxServer Database Result Error ------------- -------- ------ ----- E15MB2 Mailbox Database 2 Success
You can also specify a remote Mailbox server to test all of the active databases on that server.
[PS] C:\>Test-MAPIConnectivity -Server E15MB1 MailboxServer Database Result Error ------------- -------- ------ ----- E15MB1 Mailbox Database 1 Success
Notice what happens if a Mailbox server with no active databases is tested.
[PS] C:\>Test-MAPIConnectivity -Server E15MB3 WARNING: The operation could not be performed because no mailbox database is currently hosted on server E15MB3.
The test will use the system mailbox on each database, but you can also specify a mailbox and the test will run on whichever database that mailbox is hosted on. This is useful if you have a need to verify connectivity for a specific mailbox.
[PS] C:\>Test-MAPIConnectivity -Identity paul.cunningham MailboxServer Database Result Error ------------- -------- ------ ----- E15MB1 Mailbox Database 1 Success
Individual mailbox databases can also be tested directly.
[PS] C:\>Test-MAPIConnectivity -Database "Mailbox Database 1" MailboxServer Database Result Error ------------- -------- ------ ----- E15MB1 Mailbox Database 1 Success
And of course you can use the pipeline to test multiple databases at the same time. You can also pipe the output to Format-List to see more details, such as the latency recorded by the test.

Tip: When someone asks me “Hey, is there something wrong with Exchange?”, one of the first cmdlets I will run is Test-MAPIConnectivity.

Hello Paul ,
Thanks for the article .
Please correct me if i am wrong .
In exchange 2013 all the outlook client connectivity will happen through outlook anywhere i.e (rpc over http) and also with MAPI over http on the case where the client is with outlook 2013 and latest service packs .Especially MAPI protocol is not aware for exchange 2013 products .
So such case how could we use the test-mapiconnectivity command to check the issue on the mailbox access in exchange 2013 .
Correct me if anything is wrong.
If the database is dismounted or is not responding correctly the test will fail, so it’s still a useful test. But like all tests it only gives you part of the picture.
Hello Paul ,
Thanks for the prompt reply .
In exchange 2010 we can make use of the below mentioned command to check the outlook client connectivity
test-mapiconnectivity -identity “name of the user” | ft -au
For exchange 2013 Could you please share me exchange management shell command to check the outlook client connectivity that happens either through RPC over HTTP or MAPI over HTTP ?
Also i would like you to share me the exact link on where i can ask exchange related questions in exchangeserverpro forum ?
Note : Really your blogs are more informative 🙂 and i would like to learn a lot from your blogs please keep on doing the best .
Hi!
i have followed your post and there are very good but…
i have a problem! i have 3 Exchange server 2013 CU8 but one of them is failing because did not respond by owa neither outlook .
i have configured all the virtual directories according your instructions but when i move a mailbox to the mailbox database to the new server the owa is blank and the Outlook says “Microsoft Exchange is unavailable Outlook must be online or connect to completed this action”
how can i test my Exchange? i can not move mailboxes to these server please help me!
thanks and greats!
Sounds like you’ve got some unhealthy or inactive server components on that server. Run “Get-ServerComponentState SERVERNAME” to check.
Running CU8 also puts you out of support so I recommend you upgrade to CU10.
Dear Paul,
I am really interested in your blogs.. ..
A quick Question.
How to change the present rpc/http to mapi/http. I have migrated all my Exch Srv to Exch Srv 2013 SP1 CU8. But still when i look at my client it seems to be using RPC/HTTP. So does this happen automatically to MAPI/HTTP or do i need to change it manually from PowerShell.
And when i check to see if MAPI/HTTP is running . It shows it is running and ACTIVE.
please help.
You should check that you’ve completed all the steps in this article:

How do you get this command to run in anything except the Exchange Management Shell?
What do you mean? It is a PowerShell cmdlet so you need to run it in PowerShell (Exchange Management Shell).
