We are unable to receive calendar events from a specific domain, but emails from this domain without Calendar events attached are received without a problem.  We are using Exchange 2007.

Attached is a copy of the Diagnostic information for administrators that our server is returning to the user trying to send us the Calendar events.

Diagnostic information for administrators:
