<div>Everyone else works.  If I point that Unity user to a different mailbox it works correctly.  To me this looks like an issue with Exchange on that mailbox but the client isnt convinced.  All users are on the same CAS and same Datastore.  They only change made in the last couple weeks was the upgrade from Exchange 2010 SP1 to SP2.  I did have them add the throttling policy into Exchange for the unity service account.</div>

<div>Any thoughts?</div>
