When you enable a user for Unified Messaging (UM), you must define at least one extension number that Unified Messaging will use 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 extension numbers from the user's mailbox by configuring the Exchange Unified Messaging proxy address (EUM proxy address) on the user's mailbox.
