I have problem with one of our users not able to access calendar. It is only one user and others are fine. I have windows 2003 SP 2 and Exchange 2003 with SP 2. When I go to event viever I get Event ID 3005 and http error 500 it says:
Unexpected Exchange mailbox Server error: Server ts.domain.com User: [email@example.com] HTTP status code::. Verify that Exchange mailbox Server is working correctly.
What is happening is that user is not able to sync calendar on her mobile device iPhone.
We have only one server no front and back configuration one server that is hosting exchange
It affects only one user everyone else is fine.
