Outlook addressing question (any version)

When creating an email in MS Outlook, you can type the first couple of letters of an email address in the "To" field, and a list of email addresses starting with those letters will appear. It seems to be a cache of people I have sent email to before or that I have received email from. My question is where does this list come from and is it possible to export it so that a user gets the same list on a new computer?

 

Found it. It's in the "Nickname file ". http://support.microsoft.com/?kbid=287623

I couldn't find the file at first. Showing hidden files and folders isn't enough; you still have to tell 'Search' to search the hidden files.
