I have one Exchange 2003 mailbox server and one Exchange 2003 front end server both running on windows 2003 standard. Active Sync enabled to allow smart phones to sync. After we switched to Office 2010 in Jan, users started to get "Account Error" periodically on their smart phones and were not able to sync until I reboot the exchange mailbox server. it's getting to a point now I have to reboot the mailbox server daily. Same Users were not affected when using Outlook or Outlook Web Access when not able to sync via smart phones. No errors were logged in either application or system event log on both exchange servers.
Anyone has any insight on what might happen and how to fix this? Thank you.
