Administration
Tip: Maintaining
Address Lists That Are Based
on Group Membership
Posted: June 05, 2002
By using Exchange 2000, administrators
can create address lists based on specified
criteria. For example, if you are an administrator,
you can create an address list based on
the Company attribute of an object so that, for
example, only objects with a company
name "Microsoft" are displayed in the
address list.
You can also use group membership as a criterion
for an address list. However, if you do,
you must take one of the following special measures
when you add users to groups or
remove users from groups:
Manually start a rebuild of the Recipient Update
Service.
Modify an additional attribute of the user that
you are adding or removing from a
group.
Performing one of these modifications is necessary
because, in Microsoft Active
Directory® directory service, the user object
does not include group membership
information. Active Directory calculates a user's
group membership on an as-needed
basis. When you make a user a member of a group,
no new information is stored with the
user object. Because no new information is stored
and the object has not been formally
updated, the Recipient Update Service does not
automatically check to determine whether
the object belongs on new address lists.
If you start a rebuild manually, the Recipient
Update Service updates the address lists as
usual. If you modify a static attribute of the
user object, that is, an attribute for which
value is not automatically calculated, the Recipient
Update Service automatically detects
that the user object was modified and updates
the appropriate address lists.
