Any public distribution list in your Exchange directory can be imported into Unity and given a voice name and extension number if you wish. When forwarding a message from the subscriber conversation you can find this distribution list by spelling it's name or by entering the ID depending on which addressing method you prefer.

If you want to have outside callers leave messages for a distribution list you want to setup a call handler that has your greeting and that is setup to take a message in the after greeting action. You can setup the recipient for messages taken by that call handler to be a subscriber or a public distribution list. This sounds like what you want to do... then users can dial the ID of the call handler or route there via a one key rule and leave a message for a group of subscribers.
