We are running Unity 5.x and are intergrated with Exchange. We have 1 user who does not want to get voicemails in his email. I changed the class of service for this person so that they are Voice Messaging not Unified Messaging but the email keeps showing up. Am I missing something?
In a UM environment, all users are UM by default. To make this user VM only, you would need to:
1. Delete the subscriber account in Unity
2. Add a new AD account such as "user-VM"
3. Import this user into Unity
Hope this helps.
