Is this a random new issue or did it happen after some changes?

You did not mention the exchange version here, However as you mentioned backend and frontend servers, I am considering thet you on exchange 2003 environment.

I suspect the issue the OWA virtual directory, Have you delete and to re-create the virtual directories for Outlook Web Access?

You didn't mentioned exact error message? Have you checked in IIS logs? Is this happening in Outlook as well? Have you checked the SyncIssues folder in Outlook? Do you see any application/system event logs on both BE & FE servers?

However, I had similar issue and got resolved after unhooking the Anti-Virus. If you have any AV, please disable all services and if this is Exchange aware AV, then disable both the registry kesy


Proactive Scanning - Set to 0
Enabled - Set to 0 (By default, when you stop & disable all AV services, this will become 0)
Background - Set to 0

Somestimes, this could cause if AV signature's has any issues. After updating new signature files and turned on the AV services, never this issue back again.
Thanks for all you responses, I found the culprit !!!, it's the Symantec Mail Security for Microsoft Exchange (SMSMSE).....the license expired and was recetly renewed.  It seems the installation of the new license didn't quite go through properly, I've temporarily disabled the the SMSMSE and users can now open their mail items, while I figure out how to unistall the old license completely and install the new one
