Disable voice mail for a user in Exchange Server

Applies to: Exchange Server 2013, Exchange Server 2016

You can disable Unified Messaging (UM) for a UM-enabled user. When you do this, the user can no longer use the voice mail features found in Unified Messaging. If you prefer, when you disable UM for a user, you can keep the UM settings for the user.

For additional management tasks related to users who are enabled for voice mail, see Voice mail-enabled user procedures.
