I have a user that is getting errors(Operation failed) in Outlook 2003. The E-mails have other attached E-mails with attached Docs in them. If she restarts Outlook, it may work or it may not. It seems random when clicking on the atttachments to get the error, sometimes it pops up sometimes not. I forwarded one of the E-mails to myself and have no issues, so it's her issue. I gave her a new outlook profile and renamed Frmcache.dat, still does it. Not sure what else it could be.
