Address Books
The Address Book is a collection of address books provided by Microsoft Outlook, Microsoft Exchange Server, or Internet directory services, depending on how you have set up Outlook. You can use the Address Book to look up and select names, e-mail addresses, and distribution lists when you address messages. When you type a name in the To, Cc, or Bcc box of an e-mail message, Outlook automatically checks to see if the name you typed matches a name in the Address Book. If there is a match, the name is resolved and you can send the message. If there is no match, Outlook prompts you for more information by way of the Check Names dialog box. You can also quickly search for names by typing them in the Find a contact box on the Standard toolbar.

There can be several types of address books displayed in the Address Book dialog box:
Global Address List - The Global Address List is a feature of Microsoft Exchange Server that contains all user and distribution list e-mail addresses in your organization. The administrator creates and maintains this address book. It can also contain public folder e-mail addresses. You can download the Global Address List for use offline.

Internet directory services (LDAP) - Internet directory services are used to find e-mail addresses that are not in a local address book or a corporate-wide directory such as the Global Address List. An Internet connection is required to view an LDAP address book unless the LDAP directory is part of your organization's network.

Outlook Address Book/Contacts - The Outlook Address Book is created automatically and contains the contacts in your Contacts folder, which it displays in the Address Book dialog box when you click Contacts in the Show names from the list. Use the Contacts folder to store and retrieve all types of information about others, such as street addresses, phone numbers, e-mail addresses, fax numbers, and Web page addresses. When you update your contacts, the Outlook Address Book is updated as well. It is recommended that you convert your Personal Address Book to Outlook contacts, because contacts support distribution lists, display (friendly) names, aliases, and all the other features that Personal Address Books support. Outlook contacts are also fully integrated into Outlook, providing flexibility and customization that is not available in the Personal Address Book. For example, you can associate birthdays, several types of phone numbers, anniversaries, and other custom information with your contacts. You can also sort, filter, and view your contacts in customized ways; for example, by last name first, or by some attribute, such as postal code. And of course, you can also print your view using the customizable printing provided by Outlook. The Outlook Address Book is available offline.

Personal Address Book - A Personal Address Book is used to store distribution lists you use frequently, such as a list of everyone on the racquetball team. Personal Address Book files have a .pab extension and can be copied to a disk. You can keep the e-mail addresses of your personal contacts in either the Microsoft Outlook Contacts folder, which is recommended, or the Microsoft Exchange Personal Address Book. The Personal Address Book is available offline.

Third-Party Address Books - Third-party address books can be added to Outlook by using the third-party provider's Setup program. Outlook displays third-party address books in the Additional Address Book Types list.
