Hi,

Make sure to have the folder options view to all files, even hidden files, maybe the file is hidden. Then do a search (what else is knew)..

The .pst file is located in
C:\Documents and Settings\{user name}\Local Settings\Application Data\Microsoft\Outlook

You might also want to check that your assistant didn't associate .pst files to "Channel registeration Helper applcation "
Within Windows Explorer, Tools/Folder Options/File Options/PST
It should be "Office Data Files"

If it's something else,
Delete PST entry, Find PST file from above and double click, and reassociate back to MS Outlook
