Do you by any chance receive the following in Event Viewer:
Event Type: Error
Event Source: MSExchangeAL
Event Category: Service Controller
Event ID: 8231
Computer: RootServer
Description: Permanent failure reported by policy group provider for
'CN=Recipient Policies,CN=Exchange_Organization,CN=Microsoft
Exchange,CN=Services,CN=Configuration,DC=DOMAIN-A,DC=com':'MAD.EXE',
error=8000ffff. Taking provider offline.
Cause
This issue may occur if Domain Name System (DNS) name resolution between the
Exchange server that is running the Recipient Update Service and the target
domain controller that is in the remote domain is malfunctioning.
Additionally, this issue may occur if the Short Name for the remote domain DC
is not resolvable, even if the FQDN can be resolved (the Short Name is the
NetBIOS name.) The Recipient Update Service may not be able to process users
in the remote Windows domain.
