When trying to backup my office outlook, I receive an error message that
states:an unexpected error is preventing the operation. Make a note of this
error code, which might be useful if you get additional hdlp to rewolve this
problem:
Error 0x80070021: The process cannot access the file because another process
has locked a portion of the file.

Please help.

How are you trying to back up your PST? Is Outlook running?
--
f.h.

It means, either OL has failed to exit properly (check running processes in
Task Manager)
or that another App has a hook into the data file, eg DeskTop search, sync
app etc

I got this message and found that unplugging the sync cable for my
phone allowed the backup to run.
