I am currently having an issue with Exchange crashing every 2 days at roughly 4:42AM. The exchange services are running but Outlook will not connect to the server. Also, in the application log, I have tons of failed attempts by iPhone users.
I checked the application log for any warnings/errors that may give me some clue of whats going on, but nothing is there.
If I attempt to connect via OWA, I get: HTTP status code: . Verify that the Exchange mailbox Server is working correctly.
I am at a loss right now and I am not sure where to move from here. A simple reboot will 'fix' the problem, but I know it will just go down again.
