What Are Address Lists?

          Address lists are used to group recipient objects based on a LDAP query for specific AD DS attributes. You can use address lists to sort the GAL into multiple views, which makes it easier to locate recipients. This is especially helpful for very large or highly segmented organizations.
          You can configure address lists with recipient filters that determine which objects belong in each address list. Address lists are evaluated every time a mail-enabled account is modified to determine on which address lists it should appear.
