Problem backing up .pst files

[Stelio]

I have recently changed to Windows Vista and loaded Outlook 2003 on it. On
windows XP I could lookup my .pst files and copy them to an external backup
device.

I cannot seem to do so with Vista. I kep getting the error:

0x80070021: The process cannot access this file because another process has
locked a portion of this file.

My outlook is closed when trying to do this...

Outlook might be closed but something is hijacking the outlook.exe process
which has the lock on the file. As long as that process runs, you cannot do
anything with the pst-files.

Usually this is the result of a certain add-in that you have installed or an
application that relies on the outlook.exe process such as fax software or
having a mobile device connected to your PC.

This can be caused by a search program indexing the PST or by an antivirus
program scanning the PST.
