For the past several months, we have been having issues with our mobile phone users occasionally not being able to send or receive mail. My Samsung Captivate (Android 2.2) will show a little yellow message "could not connect to server" when it tries to sync. If I log on to our CAS/hub transport Exchange 2007 server and run a Test-ActiveSyncConnectivity command in the EMS, I get an error that it can't communicate with the mailbox server. Looking in the event log, I find event 1022 with the following: The connection between the Client Access server and Mailbox server "lei-exchg1.leisurearts.net" failed. If this event is logged infrequently or only during scheduled downtime for a Mailbox server, no user action is required. If this event occurs repeatedly, check network connectivity using PING or PingPath. Also, check connectivity using the Test-ActiveSyncConnectivity cmdlet. More information: Microsoft.Exchange.Data.Storage.ConnectionFailedTransientException: Event Manager was not created. ---> Microsoft.Mapi.MapiExceptionNetworkError: MapiExceptionNetworkError: Unable to make admin interface connection to server.

Sometimes the system will go for days without having this problem, sometimes I'll have to reboot the hub transport server three times in one day.But one thing is almost constant: this almost NEVER happens during business hours, but happens frequently at night and on weekends. At first I thought our backup jobs might be affecting network communication, but we're on a Gbit switch, and I've even checked to see what jobs were running at the time of the errors, and sometimes they happen in the early evening before backups even start running. Both Exchange 2007 servers are on SP3 with the latest rollup that came out two weeks ago.
