The very useful Outlook Personal Folders Backup Add-In at first appears not to work on Office 2010. When you try to install it the options dialog will be missing from the menu and you will not be reminded to backup when closing Outlook.
Actually the menu is still there, moved across into the “Add-Ins” tab of the ribbon bar. But the main functionality, the backup prompt, requires the following registry settings change:
- Run REGEDIT (as Administrator on Vista or Windows 7) then locate the registry key: KEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins\Microsoft.OutlookBackup.1
- Add a new DWORD value (select 32bit DWORD on 64bit systems) called
RequireShutdownNotification then set it to 1.
This fix will work on both 64bit and 32bit systems. Credit goes to this article where I found the solution.
