I had a problem with a .pst file over 2GB. I trimed it, scaned it and could view it. Outlook unfortunatly did not work. I had to reinstall XP and Office and with a new profile the email is functional. The problem now is opening the old email file. It shows up in folder view but will not display in the content panes, it just gives the error "unable to display the folder." I have looked around and this might be permissions related?
