File IMPORT/EXPORT within Outlook - I had exported to a PST file, that I
imported from
Never export to a PST. Never import from a PST. Do you save your Word
documents as Plain Text and then reconvert them to Word when you change PCs?
That's what importing and exporting is like. It is meant for moving data
between Outlook and some non-Outlook program, not between one Outlook and
another. Go back to the ORIGINAL PST (the one you exported from
originally), copy that PST to your new PC and connect that PST to your
Outlook profile using the Mail applet in Control Panel.
