When a user sends a message to a global distribution or security group in a multidomain forest, the users in the global distribution group may not receive the message. The last entry in the tracking logs is a submission to categorizer.
The person who sends the message does not receive a non-delivery report (NDR). The sent message disappears and is not delivered. The message to the Global DL that has disappeared in CAT cannot be retrieved. It is not in the Queue directory or in the Temp table.
Mail that is sent directly to individual members of the global groups delivers successfully.
This issue can occur if you use global distribution groups in a multidomain forest. Domain global distribution group membership appears only on global catalogs in the domain of that group.
To resolve this issue, use universal distribution groups rather than global or domain local scope to ensure proper e-mail delivery. Universal distribution groups most closely resemble Exchange Server 4.x, 5.0, and 5.5 distribution lists.
There are three scopes for distribution group accounts in Microsoft Windows 2000 Server: domain local, global, and universal.
