YES, it is fully closed and to the best of my knowledge it is not running. I
will check it in service to be sure.

If the Processes tab of Task Manager does not show OUTLOOK.EXE, then something
else is locking the PST. The most likely culprits are a desktop search
program, like Google Desktop Search, or an antivirus scanner. You should be
able to boot your PC in Safe mode and make the copy.
