I would take a copy of the PST file and attempt to open it in Outlook.
If Outlook can open the message confirm with your user if everything appears
to be there. If it is just export the PST to either another PST or
preferably some on of the text format likes tab or comma delimated. Both of
the text formats will not bring over corrupt items and you can manually edit
the file if you need to before importing it into Exchange via Outlook.
If data is missing I would say you are probably out of luck at this
point.
You can have a large amount of empty space in a PST if a user has
deleted large numbers of items and then not run a database pack on the PST.
This will create a large amount of dead space in the PST file until a full
pack is performed.

Hey guys,

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. The pst is 605 meg, and no matter what i
do, i can "recover" about 110 megs of mail. I;ve run scanpst.exe, a few
free tools that claim to be able to read pst files. Regardless if i use
one of these pst readers, or outlook, it only shows me the 110 meg of
mail. So my question is, A can there really be ~500 of dead space in the
pst file, and B is there any real chance of me recovering these emails?
The next step i plan on taking is this

and after that im gonna resort to a peice of commercial software such as
this. http://www.repair-outlook.com/

Does anyone have any advice to give?
