There are third party utilities which will do this:

Upstart is a utility for converting and merging Outlook® PSTs.

It may be simpler to just open the old .PST and drag and drop it's contents
into the new one.

"Not savvy enough" Not savvy wrote in
message ...
Ok, it took me over a week to figure out how to copy my .pst file from my
old
computer (XP & Outlook 2003) to my new computer. In the meantime, I was
afraid I wouldn't be able to do it at all, so I started using the new
version.

Now, I have successfully copied the old .pst file to the appropriate
folder.
But I'd rather not have to recreate everything I've done in the new one in
the meantime, and I'm not sure how I'd get my emails.

Is there a way to merge the two .pst files into a single file that Outlook
will read and use?
