+ 0 Votes Microsoft's Backup Utility & Others prouddad97 5 years ago Oh yeah, I downloaded from Microsoft, its free utility for Outlook 2003 that backs up Outlook's PST files when I close the program. In addition to that, my routine data backups always include ALL of my Outlook data folders. I don't think though, that this includes nk2 files (autocomplete for email). I'm wondering if there are any advantages to owning Outlook-specific backup programs in addition to the ease of restoring data, scheduled backups and encryption. Nobody--even the Outlook-specific backup program manufacturers have given me a straight answer to this question yet. Also--do you know if any of these Outlook-specific backup programs include the backup of email name & email address autocomplete data?
