Yes. The PST file, of course.
Never import Outlook data files. Just open them. What makes you think you
can't open the PST file from your previous installation? There is no reason
you couldn't.

Hi Russ,
I have been unable to locate the PST file from my previous
installation. I used searched for "*.pst" and nothing came up. I
thought that unless you specifically created a .pst file via the export
feature in Outlook that you would not have one. Am I mistaken? If so,
where should I be looking for this file?

Outlook always creates a PST file when you use POP/SMTP accounts. It has to.
Otherwise there is no place to store your data. PST files are hidden files.
Take a look at these pages for info on Outlook data backup or transfer:
