When I was using Win 98 SE, I exported my contact list from Out Look Express. It exported as a .pst file extention. Now that I upgraded to XP Pro, the same Out Look Express will not/can not reccognize this file extention. I even tried to import it back into my 98 machine without any success, same error, it can't read the file format. I can't even open it up via Word/Note Pad. I'm stumpted being that it's the same program that exported, but can't import. Any suggestions?
