You have to close Outlook to backup the pst file. Outlook puts an exclusive 
lock on the pst when it is open and therefore cannot be backed up. I have the 
same problem.
Solution to this problem.
"If you need your personal folder to be backed up, make sure you close outlook 
when you go home." is the message that needs to go out to the clients.
