Hi
It is a pain this one, i have had it a few times with PST files and other corrupt files too.
Only thing i can suggest is for you to re-create the PST files if you can, not sure how easy this is though. We used to deal with PST files a lot but then we got Exchange and that got rid of them, i would strongly recomend Exchange by the way if you dont have it (i am not a salesman!)
