Not that I know of. What errors do you have, and what happens when you run
scanpst? How big is your PST file? If you're not running OL2003 (with a PST
file created therein) there's an official 2GB limit on PST files, but
problems usually turn up closer to 1.2 - 1.5 GB. If this is your problem,
you'll need the following utility to crop it and render it useable (make
sure to make a backup of your PST file first, and note that you will
probably lose some data)
