I am looking to build a Unity server that will be using an existing Domino server for mail store, but for voice mail only. My question is, do I need to create separate AD accounts for the users so that they do not receive the voice mail messages in their email Inbox? Also, what is the best strategy in this case when we do go UM? Would the Unity server need to be rebuild? Or can we just recreate subscribers to match the alias of their mail box and somehow manually move their voice mail to their mail box?
