Exch2007 -> Exch2010 ActiveSync Question RRS feed

  • Question

  • I have an existing Exch2007 server on Windows 2008R2 and I'm migrating to a new server running Exch2010 and Windows 2008R2.

    I've noticed that the web access portion on Exch2010 will allow users to access their mailbox if even though the mailbox still resides on the Exch2007 server.

    However I'm wondering if this is possible with ActiveSync.  I have a mailbox on the Exch2010 that I can access no problem with ActiveSync, but if a user has a mailbox still residing on Exch2007 they cannot access using the new Exch2010 external ActiveSync address.  Essentially can ActiveSync talk between the servers in the same way that the web access portion is.

    Thanks.

  • I ran the test and it stated that I needed to enable Integrated Windows Authentication on the Exchange 2007 IIS on the Microsoft-Server-ActiveSync object.  It appears to be working now.

     

    Thanks for your help! :)

  • I assume you have a legacy URL configured to get OWA working for the 2007 mailbox users - you would use the same process for ActiveSync;

    Set-ActiveSyncVirtualDirectory -Identity \Microsoft-Server-ActiveSync -ExternalURL https://leagacydomain.com/Microsoft-Server-Activesync.

    If you have published the legacy URL via ISA or TMG you need to add the activesync path to that rule.

  • Actually my existing active sync setup points to exchange07.domain.com and my new server points to exchange10.domain.com.  If I point my users mobile devices to exchange10.domain.com they will not sync because their mailboxes still reside on the Exchange 2007 server.  If I move their mailboxes to the Exchange 2010 server they will sync fine.  The existing OWA link points to https://exchange07.domain.com and the new OWA link points to https://exchange10.domain.com (both default websites point to /owa).  And if a user logs into the new https://exchange10.domain.com website, even though their mailbox resides on Exchange 2007, they will be granted mailbox access.  I'm wondering if active sync is able to transparently open up mailboxes on either server the same way that OWA is.  I have many mobile devices that I don't want to have to change the active sync entry from exchange07.domain.com to exchange10.domain.com.

     

    Thanks.

  • Normally with 2007/2010 co-existence you would configure a legacy domain name and set that as your ExternalUrl for the client access virtual directories on the 2007 CAS.  You would then point the exchange07.domain.com to your 2010 CAS server and the clients would be redirected automatically.  

    Your Exchange07 domain is acting as the legacy URL for OWA because you have got your users to connect to a different 2010 URL.

     

    " If I point my users mobile devices to exchange10.domain.com they will not sync because their mailboxes still reside on the Exchange 2007 server"

    Have you actually tried this already?  This should work the same as OWA redirection.

  • "Have you actually tried this already? This should work the same as OWA redirection."

    Yes in fact I'm trying it right now on my Android phone.  Just to be safe I tried a regular employee who still has their mailbox on exchange07.domain.com and changed the active sync address on the droid phone to point to exchange10.domain.com - We both get an authentication error.  As soon as we switch our android phones to point to the exchange server where our mailbox resides we are able to receive our emails.

    Thanks.

  • Can you try a test with the RCA: https://www.testexchangeconnectivity.com?  Also do you have an ISA or TMG that you are connecting though?

  • Just an update, but I als found this in the event viewer on my Exchange 2007 server.  This happened when my mailbox resided on Exch2010 and my phone still pointed to the Exch2007 server. 

     

    The Exchange ActiveSync user domain\my_username has a mailbox on a newer Exchange version. Exchange ActiveSync does not support proxying users to newer Exchange versions. The user needs to connect to a newer Client Access Server.
