I have 2 outlook archives (.pst files) that I wish to merge together.

How do I do that?

The easiest way is to open one in Outlook. Then select File > Import, and import the second pst into the first, checking the "include subfolders" button.

If these are not the 2003/2007 version of PST, but are from Outlook 2000 or earlier, they have a 2 GB limit and other issues, so I would recommend creating a new PST, and importing both archives into the new one.

I agree with the answer above, but suggest adding the point to check 'do not import duplicates' underneath where you supply the path to the file. That will give you a true merge. (can't edit questions or comments yet, thus the format of a new answer.) – colmob Sep 3 '09 at 8:32
