We recently upgraded to Small Business Server 2008 from a SBS 2003 domain. Ever since then there is an issue with the Offline Address Book. Symptioms include numerous synch errors in outlook, and an error message every time that outlook tries to send & recieve. The message states:
! Task 'Microsoft Exchange Server' reported error (0x8004010F) : 'The operation failed. An object could not be found."
