My Response:

I remember reading this question before, so I decided to search previous newsletters for the answer.  Low and behold -- I found the answer in January 01, 2002's issue of the Gazette!  Jayne T. writes:

" [All you need to do is send] the contents to floppy disk [or hard drive] via the export facility in the address book and you can do the reverse with the import facility of the address book on the new machine. "

I decided to try it my own machine using the export / import feature in Outlook Express 6 on my Windows XP (Service Pack 1) machine.  Oddly enough, I received an error message stating that the operation could not be completed.
 

I decided to try Jayne's suggestion and exported the database by loading the address book by itself ... and it worked! 
 

Here's how to do it:

• Load the Address Book (Start -> Programs -> Accessories)
   
• Click File -> Export
   
• Save it as a .WAB file
   
• Load Outlook or Outlook Express
   
• Click File -> Import -> Address Book
