I have an SBS 2003 with SP2, periodically my users running active sync complain they are "not syncing" to their PDA's. When I look in the event viewer, I have the following message:
Exchange mailbox Server response timeout: Server: [server.domain.local] User: [email@example.com]. Exchange ActiveSync Server failed to communicate with the Exchange mailbox server in a timely manner. Verify that the Exchange mailbox Server is working correctly and is not overloaded.
If left alone, eventually the user begins to sync once again. Otherwise, for an immediate solutions, a server reboot triggers the sync again.
Any ideas are GREATLY appreciated.
there is an active sync warning, stating there was an error while syncing with that user" ensure the exchange server is working correclty and not overloaded" What constitutes an "overload"?? At that point I simply reboot the server and everything begins to work correctly again. Sometimes, the Information store service has to be manually started upon reboot (not sure if that shines some light). Any help is greatly appreciated.
