Outlook Error Message: Unable to open the Outlook window. The set of folders could not be opened.

For starters, we are using Exchange 2003. USer is running Windows XP, with SP2 and full updates.
I have a user whose Outlook client is giving us fits. This morning, anytime he clicked on a folder other than his Inbox, Outlook would crash. It would offer to send an error report and then reopen. I ran through all of the office updates, including service packs. This did not help. I did a detect and repair and now Outlook won't open at all. Here is the error message:
"Cannot open Microsoft Office Outlook. Unable to open the Outlook window. The set of folders could not be opened."
I've tried recreating his Outlook profile, no luck. I've examined his profile in OWA, and everything appears normal. I've deleted his OST file again and again. No luck.
I was finally able to get him up by disabling Cached Exchange Mode. However, we are back to the problem of Outlook crashing when he changes folders.
