Yes.. that's what I'm not sure how to do. How do I open a PST and set
it as my default message store??
File>Open>Outlook Data File. Browse to the PST, select it, and click OK.
This opens the PST.
Click Tools>E-mail Accounts>Next. At the bottom left there's a drop-down
labeled "Deliver new e-mail to the following location". Use it to choose
the PST you just opened. Click Finish, then stop and restart Outlook. The
PST you opened will be your delivery location. If you have any data in the
PST you had, you can open those folders and drag-and-drop the data in them
to the corresponding folders in the current default folder file or you can
simply reference it from where it is. If you move the data in the prior PST
or if you don't wish to reference it any more, you can close that PST with
right-click>Close to remove it from the folder list.
