Microsoft Outlook pst-file backup-up Add-in

The Personal Folders Backup download allows you to easily create backup copies of your .PST files at regular intervals.

Officially, this add-in only works with Outlook 2002/XP, Outlook 2003 and Outlook 2007 but can be made compatible with Outlook 2010 as well by setting a specific option in the Registry.

This add-in can’t be made compatible with Outlook 2013. Instead, consider making manual backups or one of the many other (semi-) automated ways.
