For more info, also see: How often do I need to use AutoArchive? Step 1: Set Outlook to archive by Received Dateīefore you start, you must configure Outlook to archive based on the Received date rather than the Modified date.

Of course, the backup process will take a bit longer. Note: The definition of a “large pst-file” is somewhat relative and on most systems having a pst-file of 4GB or even 10GB is no problem at all. To split it into yearly archives (or any other amount such as quarterly, or every 2 years), you can run the Archive process multiple times, each time to a new pst-file. Splitting a pst-file can be done via the Archive feature in Outlook. Is there any way I could split up my pst-file into yearly archives?
