You can remove the Unified Messaging server role from a computer running Microsoft Exchange Server 2010. When you uninstall or remove the Unified Messaging server role from an Exchange 2010 server, the server can no longer answer and process incoming calls.

In certain situations, you may have to remove the Unified Messaging server role from an Exchange 2010 server. If the Unified Messaging server role has been installed on the same server as another Exchange 2010 server role, you can remove the Unified Messaging server role using Setup.com.

Prerequisites

You must ensure that each of the Exchange 2010 server roles meets the appropriate prerequisites and system requirements before you begin the modification or uninstall process. For more information about server roles, see Overview of Exchange 2010 Server Roles. To understand the prerequisites for all server roles, see Exchange 2010 Prerequisites. For more information about system requirements, see Exchange 2010 System Requirements.
