I was in the process of backing up a PST before moving the client to
exchange. During this process Mcafee decides to kick on, and locks
the computer in question, and the pst file is now showing limited
emails, but the whole subfolder structure.

Why not go back to the original PST and make another copy? That should
still be intact.

By the way, when you say "backing up" instead of "copying" an alarm goes off
in my head. A backup of a PST IS just a copy. Were you doing something
other than just copying the PST?
