I have to admit this has stumped me...
User's Workstation
- Outlook 2010 (32-bit) w/ Cached Exchange Mode enabled
- Windows 7 Pro (64-bit)
Email account is on Exchange 2003
Problem
The user is unable to open certain emails in Outlook on this computer. Error msg is "Cannot open this item". The same user has a laptop with Outlook 2010 (32-bit) and Windows 7 Pro (32-bit). On his laptop he CAN open these emails without any problems. So to me that says this is a bug with Windows 7 Pro (64-bit). He can also open these emails on his BlackBerry.
Things I've tried to fix this problem...
- Recreate his Outlook profile from scratch
- Recreate his Windows user profile from scratch
- Reinstall Office 2010 from scratch
- Move his Exchange mailbox to a different storage group on the server
- Installed a Microsoft Hotfix that supposedly fixes the problem (it did not)
Strange thing is - most of the emails he cannot open were emails sent to him from a BlackBerry within the organization. Coincidence?
Any help is greatly appreciated!
