Your post is confusing because there is no Address Book in Outlook. All data
is stored in Contacts Folders.
If that's what you want to transfer:
The file you need is your Personal Folders file (*.pst) It's where all the
mail, calendar, contacts etc are stored.
Take a look at these pages for info on Outlook data backup or transfer:
