Modify an E.164 Address for a UM-Enabled User

 

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

Topic Last Modified: 2012-07-23

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. However, you have the option to modify an E.164 address for a user if the user is associated with an E.164 dial plan. After you enable the user for Unified Messaging, you can modify E.164 addresses for the user's mailbox by configuring the Exchange Unified Messaging proxy address (EUM proxy address) on the user's mailbox.

Looking for other management tasks related to UM users? Check out Managing Unified Messaging Users.

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "UM mailboxes" entry in the Unified Messaging Permissions topic.

  1. In the console tree, navigate to Recipient Configuration > Mailbox.

  2. In the result pane, select the mailbox for which you want to modify an E.164 address.

  3. In the action pane, under the mailbox name, click Properties.

  4. In <Mailbox User> Properties, click the E-Mail Addresses tab.

  5. Select the appropriate EUM address, and then click Edit. In UM Address (Extension), in the Address/Extension box, type the new E.164 address.

  6. In the Dial plan (Phone context) box, click Browse to locate the dial plan for the user.

  7. Click Apply, and then click OK.

This example modifies an E.164 address for Tony Smith, a UM-enabled user.

noteNote:
You must determine the position of the EUM address that you want to modify. To determine the position of the EUM proxy address, use the $mbx.EmailAddresses command. The first proxy address in the list will be 0.
$mbx=Get-Mailbox tony.smith
$mbx.EmailAddresses.Item(1)="eum:+14255550123;phone-context=MyDialPlan.contoso.com"
Set-Mailbox tony.smith -EmailAddresses $mbx.EmailAddresses
