Sync Issues after Migration from Exchange 2007 to Exchange 2010


I have a BES 5.04 Server with Exchange 2007 Server. Introduced a Ex 2010 Server & gave the relevant permission required for BES To work & moved the Service Mailbox to the New 2010 Server + Moved a Pilot Mailbox for which BES was enabled & working to the  Exchange 2010 Environment & things went smooth - Email sync was working without any issues

After a week moved few more accounts & could see that  the sync is no longer happening - Moved back the mailboxes to the 2007 Server & it works again.


IEMSTest is clean - doesnt seem to be a permission issue.

Have restarted both the CAS & the BEs Server - didnt help

Did a Hostfile entry for CAS - didnt help
