Clients' Offline Address Book not updated after migration from Exchange 2003 to 2010.

Hello,

I've recently migrated from an Exchange 2003 server to an Exchange 2010 server.  At this time, all mailboxes have been moved over to Exchagen 2010.  All Exchange services on 2003 have been turned off.  (Testing period).

One thing that has surfaced is that Outlook clients are not seeing the most current contents of the Global Address List.  I imagine they are not "looking" at the Offline Address Book being pulled from the 2010 server.  If I deselect "Used Cached Exchange Mode", I am able to see the current GAL.  

Where can I check and ensure that the client workstations are accessing the correct OAB?

Thanks in advance.

Regards,
Real-Timer

In the EMC, you can look at the properties of the mailbox database and under the client tab you will see the OAB you are using. OAB schedule by default can take up to 48 hours to updates for Outlook clients. You can check out this solution I gave someone else for how the schedule works, how to change the schedule and what you can do to force the updates immediately if you wish.

There's LOTS of stuff that can go wrong with the OAB.  The easiest first step - run the Exchange Analyzer in the management console tools.  That can usually find most items that are configured wrong for the OAB.

Exchange Analyzer came out clean.  No issues regarding OAB.

So do they get the updates after your force and how is the schedule set? The default? 48 hours?

Are there any subfolders on the server in the directory c:\Program Files\Microsoft\Exchange Server\V14\ExchangeOAB?  How about in c:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\OAB?  If so, any files in the sub directories?  What is the date on the oab.xml if there is one in either spot?
