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.

Chances are, then, that the PST is toast. While Diane's idea is worth
trying, I suspect it won't work. In the majority of cases I've seen, if
Outlook says the file is not a PST, then so will SCANPST. The most common
cause is that Outlook was open when the copy of the PST was made. There is
substantial anecdotal evidence, as well, that some CD burning software
doesn't handle PSTs well and corrupts them when they're burned.

I would really like to know how to manage these vagaries of PSTs
better. The problem of the CD burner being implicated is a bit scary,
particularly as I use PSTs as part of my archive strategy.

What I have noticed is that Outlook will lock a recently created PST,
thereby preventing copying. After saving a few more PSTs the earlier
PSTs seem to become unlocked and then appear available to be copied.

To maximize my chance of success though, I always close Outlook before
copying a PST.
