I have a Windows 2003 server running Exchange 2003. I had Activesync up and running without problems. We had a long power outage on Saturday and when the server came back up Activesync would no longer work. No one with email set up on their phones can connect to the server. I have since restarted the server and still no luck with Activesync.
I used the Access My Lan Activesync tester and it fails under verifying certificate and user permissions. It says ActiveSync detected, but not enabled. [ActiveSync disabled globally or for this user?]. I checked and activesync is globally enabled and enabled on the user level as well.
In the Event Logs there are a ton of Event ID 3012 Activesync errors that say: An error occurred while accessing the Active Directory for user [Internet Guest Account]. Information cannot be retrieved from Active Directory due to an unknown error. Verify that the Exchange ActiveSync Server can communicate with Active Directory, and that the user has a valid account.
I’m not sure what happened. Everything was working fine before the server went down because of the power outage. Normal mail and OWA is working fine. Any help is appreciated. Thanks.
