This problem only affects 1 user who was previously working fine. All other users are working OK. When this user tries to sync his Exchange from mobile phone, the mail does not sync. Error on the SBS2003 event log reads:
Unexpected Exchange mailbox Server error: Server [server name] User [User@domain.com] HTTP status code: . Verify that the Exchange mailbox server is working correctly.
We have tried unning the 'Connect to Internet' wizzard again and also verified the user is in the correct user groups.
Suggestions most welcome.
