I'm seeing issues with blackberrys in Exchange 2003/Outlook 2007 cached mode testing. Messages go to the Sync Issues/Conflicts folder (not shown by default) on the C: as well as the Inbox. Deletes on the PC take 30 minutes to sync, but deletes on the BB sync to the Desktop within a minute. Hmmm. Not seeing the Sync Issues email on all clients with blackberrys. Have recreated the Outlook profile and the .ost file with only temporary reprieve of extra emails. Problem returned in < a day.
