More Information about .pst files

Outlook uses .pst files to store all of it's data. Each root-level 'mailbox' on the left side of outlook represents a single .pst file. Right-click -> Properties will show you the location of the .pst file.

Unfortunately, you can't make a backup of your important Outlook .pst files (this is where all your archive data resides) while you are using Outlook.

Note : If your Outlook is connected to a corporate Microsoft Exchange server you probably are using a .pst file for archives.

• Outback works passively, so if you do nothing, it will back up your files. 
• Although Outback delays the start of Outlook (whenever a backup is required), it has a checkbox to start with Windows and another checkbox to start Outlook when it’s finished.  So you can walk away once you get Windows logged on.
• Outback checks timestamps to see if your files are already up-to-date and doesn’t bother with the copy if they are.  Unfortunately timestamps are always updated even if Outlook just loads the .pst.
• Using other methods, If you cancel the file copy progress, the backup file it was working on gets deleted - so you end up with no backup of that file.  Not so for Outback.
• Outback auto-adds any new .pst files that get added to Outlook.
