Core Issue
The Subscriber created, but was not added to distribution list due to error message is displayed when an existing Cisco Unity subscriber (who is a member of the AllSubscriber Public Distribution List (PDL) by default) is deleted and re-imported in an E2K environment. This happens when such a subscriber is deleted from Cisco Unity because the subscriber remains a member of the PDL. Even though this subscriber is deleted, the subscriber receives messages addressed to the PDL (only email messages, not voice mail messages).
When the subscriber is re-imported, Cisco Unity automatically tries to add the subscriber to the AllSubscriber PDL. As this subscriber is already a member, Cisco Unity displays an error message.
Note: This problem only happens if the same subscriber template is used to re-import the subscriber. Consequently, the new subscriber is assigned to the same PDL. Similar issues can occur with a connection to a Domino Mail Store.
Resolution
This problem can be fixed if the AllSubscriber PDL is removed from the Default Subscriber template. The subscriber can also be deleted, and re-imported with a different template that makes the subscriber a member of a different PDL and NOT a member of the AllSubscriber PDL.

Note: The Subscriber created, but was not added to distribution list due to error message can also be encountered when Cisco Unity with IBM Lotus Domino is used. For more information on this, refer to When a subscriber is added or re-imported in Cisco Unity 4.x with IBM Lotus Domino, the "Subscriber created, but was not added to distribution list due to error" message is displayed.
