cryptic error from Test-ActiveSyncConnectivity

  • Article

I came across some strange output when running the Exchange 2007 commandlet

 Test-ActiveSyncConnectivity

so I thought I'd share with those of you who might be trying to figure out what it means...

 

Test-ActiveSyncConnectivity -ClientAccessServer 02e2k7cas -TrustAnySSLCertificate:$true -LightMode:$true

CasServer MailboxServer Scenario Result Latency(MS) Error

--------- ------------- -------- ------ ----------- -----

The remote server returned an error: (403) Forbidden.

In the IIS logs I saw this:

The LegacyDeviceOnStrictPolicy helped me remember I had disabled ActiveSync for nonprovisionable devices here:

 EAS mailbox policy

So, the error, although cryptic at first, was really there to tell me the account I tested has a mailbox policy that doesn't allow nonprovisionable devices. If you use System Center Operations Manager, you may also run into this error.
