If you use Outlook with an Exchange Server account, your address book list will include the Global Address List (GAL). The GAL contains the names and email addresses of everyone that has an account with that Exchange Server and is configured automatically by Exchange.

If you're using classic Outlook, you also have the options to add or remove an address book. Adding and removing address books is not supported in new Outlook.
