Hi!
In Exchange environments, this happens when you run Permissions Wizard without the "Allow Cisco Unity to Administer Active Directory" checkbox selected. You can rerun PW with this option or add the users to the PDL via ADUC.
Unity integrated with domino does not allow users to add members to a distribution list.
You will need to get the domino admin to add the members to the list and then import them.

Hope this helps!
