When a message sent to a group is not delivered, you can specify
that delivery reports be sent to a group owner. The delivery report
lets the group owner know that the message was not delivered.
On the Start menu, point to
Programs, point to Administrative Tools, and then
click Active Directory Users and Computers.
In Active Directory Users and Computers, on the
View menu, click Advanced Features.
In the console tree, expand the Windows 2000 domain.
Double-click Users, or double-click the node that contains
the recipient information you want to modify.
In the details pane, double-click the group you want to
modify.
On the Exchange Advanced tab, select Send delivery
reports to group owner.
