Remove a SIP Address for a UM-Enabled User

  • Article

Applies to: Exchange Server 2010

When you enable a user for Unified Messaging (UM), you must define at least one extension number that will be used by Unified Messaging when voice mail is submitted to the user's Microsoft Exchange Server 2010 mailbox. After you enable the user for Unified Messaging, you can remove a Session Initiation Protocol (SIP) address by configuring the Exchange Unified Messaging proxy address (EUM proxy address) on the user's mailbox.
