found the .nk2 file as you said.

I had been doing Exports (.pst) of the entire "Personal Folders" and "Contacts".

On new PC I installed Outlook, tried to import - got errors. So copied the outlook.pst file from old PC and relocated for Outlook. Got everything EXCEPT the email address list (TO: email list).

Shpuld I try bringing over the .NK2 file from old PC?

I'll try that. (1) rename orig .NK2,
(2) copy .NK2 from old PC
