The Test-ActiveSyncConnectivity cmdlet allows you to simulate an Exchange ActiveSync connection from a mobile device to a mailbox. The mailbox can either be the test user mailbox you created earlier, or a specific mailbox user.

Running the cmdlet on a Client Access server will test the local server.

[PS] C:>Test-ActiveSyncConnectivity

CasServer  LocalSite     Scenario        Result  Latency(MS)
---------  ---------     --------        ------  -----------
e15mb1     Sydney        Options         Success
e15mb1     Sydney        FolderSync      Success
e15mb1     Sydney        First Sync      Success
e15mb1     Sydney        GetItemEstimate Success
e15mb1     Sydney        Sync Data       Success
e15mb1     Sydney        Ping            Success
e15mb1     Sydney        Sync Test Item  Success

The cmdlet can also be used to test a remote Client Access server.

[PS] C:>Test-ActiveSyncConnectivity -ClientAccessServer E15MB2

You can also test a specific URL.

[PS] C:>Test-ActiveSyncConnectivity -URL https://mail.exchange2013demo.com/Microsoft-Server-ActiveSync

If you have not provisioned the correct SSL certificates you can override the SSL trust requirement and still perform the test.

[PS] C:>Test-ActiveSyncConnectivity -TrustAnySSLCertificate

You can also use the pipeline to test multiple Client Access servers together.

[PS] C:>Get-ClientAccessServer | Test-ActiveSyncConnectivity

CasServer  LocalSite     Scenario        Result  Latency(MS)
---------  ---------     --------        ------  -----------
e15mb1     Sydney        Options         Success
e15mb1     Sydney        FolderSync      Success
e15mb1     Sydney        First Sync      Success
e15mb1     Sydney        GetItemEstimate Success
e15mb1     Sydney        Sync Data       Success
e15mb1     Sydney        Ping            Success
e15mb1     Sydney        Sync Test Item  Success
e15mb2     Sydney        Options         Success
e15mb2     Sydney        FolderSync      Success
e15mb2     Sydney        First Sync      Success
e15mb2     Sydney        GetItemEstimate Success
e15mb2     Sydney        Sync Data       Success
e15mb2     Sydney        Ping            Success
e15mb2     Sydney        Sync Test Item  Success

Finally, if you need to test a specific mailbox you can pass the credentials for that mailbox user to the cmdlet.

[PS] C:>$credential = Get-Credential -UserName e2013demopaul.cunningham -Message "Enter password"

[PS] C:>Test-ActiveSyncConnectivity -MailboxCredential $credential

    Hi Paul – Thanks to your reply.

    For Q1 – The certificate includes the following SAN (mail.ramxxx.ca, autodiscover.ramxxx.ca, ramxxx.ca) It does not include the Exchange Server name which is ex2016.ramxxx.ca

    For Q2 and Q3 – Issued by a trusted 3rd party which is Commodo + valid till Jun 2019.

    Thanks

    Hi Paul – I even tested Remote Connectivity Analyzer – The failed result is below:

    Attempting the FolderSync command on the Exchange ActiveSync session. The test of the FolderSync command failed.

    Exchange ActiveSync returned an HTTP 500 response (Internal Server Error).
    HTTP Response Headers:

    Hi Paul – Hope you can help me with this error on ActiveSync.

    When, I run Get-ClientAccessServer | Test-ActiveSyncConnectivity – I am getting below error. I am using 3rd party certificate from Comodo.

    Lab Setup – Exchange 2016 CU7 on Server 2016

    Error:

    The underlying connection was closed:
    Could not establish trust relationship for the SSL/TLS secure channel.
    Inner error [System.Security.Authentication.AuthenticationException]:
    The remote certificate is invalid according to the validation procedure.

    Thanks

      Your certificate is probably invalid then. The three requirements for certificate validity are:

      1) The name(s) on the certificate match the server name that you are connecting to
      2) The certificate is issued by a trusted certificate authority
      3) The certificate has not expired

      Did you resolve this issue? I seem to have this issue. I run a test against the path
      test-ActiveSync Connectivity -URL https://mail.domain.com/Microosft-Active-Sync

      but it fails when I run a user test
      test-ActiveSyncConnectivity -Milboxcredential (get-credential)

    Hi Paul, Thanks for the article, I came across this when I searched for load testing the Active sync traffic. Can you please help me with any information that you can to enlighten me.

  7. Florian

    I have a 2010 and a 2013 environment and a problem with the ‘extest_*’ user.

    When I run the Test-ActiveSyncConnectiviy command from a 2010 server, its succesful.
    When I run it from a 2013 server, it fails.
    Error:
    “The user and the mailbox are in different AD sites…”

    The extest_ user i still on a 2010 database and I guess, thats the problem. However, I dont want to create a new one (is it even possible to have 2 extest user in the same environment?), regarding SCOM etc.

    Is there a workaround?
