Outlook97/W2K pro – moved pst files.

In an attempt at cost saving (damn this economy) I upgraded a W95 PC to W2K. Needed to add additional HDD. Moved Exchange folder to D: and expected Outlook97 to see it (after tweeking Mail and Fax in control panel.) It worked, but folders inside O97display, but are inaccessible – O97 still thinks they are on C:. New mail comes up OK. Uninstalled / reinstalled with no change. Anybody have ideas?
