you can try using scanpst on it - run it 3 or 4 times.

Hi guys

So glad i found this grooup. I have a problem thats been driving me crazy.
I
have a new computer that had Vista OS on it and i chnaged back to XP cause
i
disliked Vista.

I had Outllok 2007 on the Vista and i burnt the pst file to a cd before i
deleted Vista and installed XP.

Then i re installed XP on the XP OS and am trying to re import/install the
pst file from cd and Outlook keeps telling me its not a valid pst file.

I have copied the file to the desktop, changed the attributes from read
only, importing it, opening it, ran scanpst.exe (and it tells me its not a
valid pst file). I'm now at my wits end.

I even tried a program called Stellar Pheonix mailbox Pro and it says its
not a pst file.

I think it might be corrupted or something in the burning process and it
contains some very important business emails etc.

HELP!!!

Thanks

Wayne
