I upgraded to Outlook 2010 from Outlook 2003 & everything went extremelyt well except for the.pst file backup. With 2003, the backup was automatic and there was one .pst backup file. Now I have 3 when open Outlook Personal Folders Backup. They are :(1) backup.pst 1.95 MB date modified 5/31/2012, (2) Personal Folders.pst 265 KB, d/m 6/20/2011 and (3) Personal Folders(1).pst 880 MB, d/m 8/6/2012. Date of last backup 7/6/2012.




When I open Outlook Personal Folders Backup there are 2 files- both the same : Personal Folders(1)




How do I make the backup automatic or how do I schedule the backup when I exit Outlook ?




And can I delete any of the 3 backup files I listed above ?




Thank you.

This is the pst file that is in your profile:

Personal Folders(1).pst 880 MB, d/m 8/6/2012. Date of last backup 7/6/2012.

This should be the backup, although the modified date doesn't fit with the last backup date on the personal folder:

backup.pst 1.95 MB date modified 5/31/2012

This is empty and can be deleted:

Personal Folders.pst 265 KB, d/m 6/20/2011

Are you using the Microsoft personal folders backup tool? You need to edit the registry to make it work.

HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins\Microsoft.OutlookBackup.1

DWORD: RequireShutdownNotification

Value: 1

See Outlook Tips | Tip 758: Personal folders backup for Outlook 2010 for a ready-to-use reg file.
