I did find that the problem SWMBO was having exporting her address book from OE has a rather simple solution.

She was trying to click "File - Export" and it demanded that she make Outlook her default program in order to do and addy book export. If you open the address book first, and click on "File - Export" in the address book it exports quite nicely as a .wab.

Hopefully there's a similarly simple solution to exporting messages in .dbx format from OE, but I really haven't had a chance to look yet.
