We run our PC's off a server (R2008). One of our staff members pst file keeps on disappearing after she logs off. She is not a roaming profile. I have searched the server and only found a temp file that is about 1.6GB, similar to the size of what her pst file was. Is there anyway to recover this temp file. The computers are running windows 7. Could it be a corrupt installation of office 2010. This also happens after she creates a backup or copys the pst file.
