Hi, got 2 computers running outlook. Doing a back up and reformat soon on one of them and as I use both computer (dekstop and laptop) for email through Outlook, emails are different etc on both machines.


anyway of 'merging' the 2 PST files.
I basically just want one computer to have outlook on with ALL my emails.
