By default, your Exchange users can access all address lists. If
you want to restrict access to a particular address list, you can
change permissions for address list members.
On the Start menu, point to
Programs, point to Microsoft Exchange, and then click
System Manager.
In the console tree, double-click Recipients, and then
double-click All Address Lists.
Right-click the address list for which you want to set
permissions, and then click Properties.
In the address list Properties dialog box, click the
Security tab.
To grant a recipient access to the address list, in
Name, select a recipient. In Permissions, next to
Read permissions, select the Allow check box.
To deny a recipient access to the address list, in Name,
select a recipient. In Permissions, next to Read
Permissions, click to clear the Allow check box.
Caution Due
to group membership, you can cause unintended effects when you deny
a recipient access to an address list if you select the Deny
check box instead of clearing the Allow check box. If you
select the Deny check box for a permission, you are denying
a permission to an object that may have inherited the permission
from its parent.
