Exchange 2016: Email Addresses and Address Books


Recipients (inclusive of users, contacts, resources, and groups) are any mail-enabled object in Active Directory to which Microsoft Exchange may deliver or route messages.


  • The recipient should have an email address for sending and receiving messages. Address books are the strategy by which users search each other in order to transmit email.


There are several distinguish methods for organizing address books.

Key terminology


  • The following terms define the core components related with email addresses and address books in Exchange 2013.


address book policies


  • Address book policies (ABPs) permit you to segment users into particular groups to offer customized views of your organization’s global address list (GAL).

  • Whenever an ABP is created, you allot a GAL, a room list, an offline address book (OAB), and one or more address lists to the policy.

  • You may then assign the ABP to mailbox users, offering them with access to a customized GAL in Outlook and Outlook Web App.

  • The main objective is to offer a simpler mechanism to achieve GAL segmentation for on-premises organizations which require multiple GALs.


address lists


  • An address list is a subset of a GAL. Each and every address list is a aggregation of one or more category of mail-enabled recipients (for instance, users, groups, contacts, public folders, conferencing, and other resources).

  • You might use address lists to organize recipients and resources, making it simple and easier for users to search the recipients and resources they require. Address lists are updated dynamically.

  • Hence, when new recipients are appended to your organization, they’re automatically by default added to the appropriate address lists.


email address policies


  • Email address policies create the primary and secondary email addresses for your recipients such that they can send and receive email. By default,Exchange indcludes an email address policy for every mail-enabled user.


hierarchical address books


  • The hierarchical address book (HAB) enables end users to search for recipients in their address book using an organizational hierarchy, like seniority or management structure.

  • Generally, users are limited to the default GAL and its concerned recipient properties and the structure of the GAL often doesn’t correctly reflect the management or seniority relationships for recipients present in your organization.

  • Being able to customize an HAB that maps to your organization’s unique business structure offers your users with an efficient method for locating internal recipients.


offline address books


  • An offline address book (OAB) is a replica of a collection of address lists which has been downloaded such that a Microsoft Outlook user is allowed to access the information it includes while disconnected from the server.
