Starting yesterday, my iphone users started reporting their email was down. Upon logging onto the server, I could see all services were up and running.
In the event log, I found 100's of these
Unexpected Exchange mailbox Server error: Server: [servername.domain.uk] User: [email@example.com] HTTP status code: . Verify that the Exchange mailbox Server is working correctly.
Upon restarting the System Attendant, everything started working.
This morning, same thing happened.
Stop/Start System Attendant, all is well.
Need to fix this by tomorrow am, any ideas why this keeps happening?
