\Outlook Archive\archive.pst" is a corrupt file. This file cannot verify. I get this when I do a full system backup. Have downloaded the updates it said. What is the problem.
The problem might be that the file is in use at the time of the backup/verify. Search this forum for 'pst' and you will find more questions on how to backup these files.
You probably will need the AOFO option to make this work.
