This guide shows you how to make a proper Outlook 2010 email archive backup.

1. Close Outlook and wait 10 seconds
2. Run: C:\Program Files\Microsoft Office\Office14\scanpst.exe or C:\Program Files (x86)\Microsoft Office\Office14\scan.pst
3. Open the file in  “C:\Users\<username>\AppData\Local\Microsoft\Outlook”
4. In case you have multiple files in the directory do step 2 and 3 several times
5. Copy the files from “C:\Users\<username>\AppData\Local\Microsoft\Outlook” to the backup location

To open the backups, just open the .pst files you copied earlier.
