Outlook stops responding when try to open a received message

There was a power brownout and one of my users PC (running Windows 98SE) shut down.  Now she can open Outlook (2000 SR1) and the new messages are received; however, when she tries to open one she just gets the hour glass and eventually Task Manager shows that Outlook stopped responding.  Outlook is being used with an Exchange Server.  I can access her Exchange mailbox from another PC with no problem.  Additionally this same thing happens when she tries to create a new message.  Here is what I have tried so far:
1.  Microsoft has an article on their site about deleting the Outlook registry keys and then doing a reinstall - did that - no change.
2.  Tried deleting the users Outlook profile and recreating it - no change.
3.  Tried completely removing Outlook from the PC and then reinstalling it - no change.
4.  Tried upgrading the Outlook to Outlook XP - no change.

can i assume at the moment you have outlook xp and if yes , is it fully updated ?

does opening new emails ONLY causing this error or any old email in her inbox ?

can you set someone else exchange account in this machine and see their mailbox can be accessed fine ?

can you remove all the new emails for her and then see if that would help.

temporarily turn off firewall , anti-spam and see if that helps

Does it work for other users on the same computer? If not then you probably are looking at a reinstallation of the OS (format the disk first, don't upgrade).

Otherwise the problem is isolated to the users registry/profile (not their exchange profile but you were close and often that would fix the problem). On an NT/XP box I would rename their profile in c:\%systemroot%\profiles\ and have them logon again which will cause a new profile to be created. I'm not sure if 98SE uses individual profiles/registry (I don't think so) and it may be a case of a rebuild or reimage the OS.
