What do you need to know before you begin? You can view the primary and secondary SIP addresses for a user by using the Get-UMMailbox cmdlet or the Get-Mailbox cmdlet in the Shell.įor additional management tasks related to users who are enabled for voice mail, see Voice mail-enabled user procedures. You can't use the UM Mailbox page in the EAC to remove a primary or secondary SIP address. You can use the Email Address page on the user's mailbox in the EAC to remove a primary or a secondary SIP address. You can use the EAC or the Shell to remove a primary or a secondary SIP address. Also, when you run the Get-UMMailbox cmdlet, the Extensions, PhoneNumber, and CallAnsweringRulesExtensions parameters will be blank or null. After the primary SIP address has been removed, the EUM proxy address for the user will be listed as Null on the user's mailbox in the EAC and when you run the Get-Mailbox cmdlet in the Shell. If you remove the primary SIP address, UM won't be able to send voice mail to the user's mailbox and call answering rules won't be processed. When a SIP address is removed, callers can no longer leave voice mail for the user at the SIP address that was removed even if the user is signed in with the SIP address assigned to the user in Communications Server or Lync Server. Any additional SIP addresses you added will be listed as secondary EUM proxy addresses. The primary SIP address you added when the user was enabled for UM will be listed as the primary EUM proxy address.

You can remove the primary SIP address that was added when the user was enabled for UM or a secondary SIP address that was added later, along with the EUM proxy address for the user. By default, the SIP address that's used by UM will be the SIP address that's used by Communications Server or Lync Server. The SIP address is used by Communications Server or Lync Server to route incoming calls and send voice mail to the user. SIP URI dial plans and SIP addresses are used when you're integrating UM and Microsoft Office Communications Server 2007 R2 or Microsoft Lync Server.

The extension number is used when the user calls in to an Outlook Voice Access number. One contains the user's extension number and the other contains a SIP address for the user. When you enable a user for UM and link them to a SIP URI dial plan, two EUM proxy addresses are created. Applies to: Exchange Server 2013, Exchange Server 2016
