In Word, when inserting an address from an Outlook contact list, using
the Address Book icon on the Quick Access Toolbar, is there a way to
change the default address book?

When we click on the Address Book icon in Word there is a drop down
list of available address books and the address book everyone uses
most frequently is halfway down the list. We'd like to be able to
change a setting so that particular address book is the default.

Thank you very much for any help!
