Our CEO is having a problem with Outlook 2007 SP2 connected to Exchange 2007 SP2. Sometimes Outlook or Exchange simply refuses to delete read messages highlighted in the Inbox. This happens when using the X icon or the delete key. Restart Outlook and the problem goes away.
I've tried applying all the latest SPs & hotfixes, MS Office Diagnostics, reinstalling Office 2007, changing operating systems even! (Vista -> Windows 7) Nothing prevents this behavior from occurring. The system is a new (<1 yr old) Dell Precision workstation with all the trimmings.
Anyone else experience this? Any ideas?
