Manage voice mail settings for a user in Exchange Server

Applies to: Exchange Server 2013, Exchange Server 2016

You can view or set the Unified Messaging (UM) and voice mail features and configuration settings for a user that's been enabled for UM and voice mail. For example, you can do the following:

  • Reset their Outlook Voice Access PIN.

  • Add a personal operator extension number.

  • Add other extension numbers.

  • Enable or disable Automatic Speech Recognition (ASR).

  • Enable or disable Call Answering Rules.

  • Enable or disable access to their email or calendar.


Some of the settings and features can only be configured by using the Shell.

For additional management tasks related to users who are enabled for voice mail, see Voice mail-enabled user procedures.

Use the EAC to view or configure a UM-enabled user's properties

  1. In the EAC, navigate to Recipients > Mailboxes.

  2. In the list view, select the mailbox for which you want to change the UM mailbox policy.

  3. In the details pane, under Phone and Voice Features > Unified Messaging, click View details.

  4. On the UM Mailbox page, click UM mailbox settings to view or change the following UM properties for an existing UM-enabled user:

    • PIN Status: This display-only field shows the status of the user's mailbox. By default, when a user is UM-enabled, the PIN status is listed as Not locked out. However, if the user has input an incorrect Outlook Voice Access PIN multiple times, the status is listed as Locked Out.

    • UM mailbox policy: This box shows the name of the UM mailbox policy associated with the UM-enabled user. You can click Browse to locate and specify the UM mailbox policy to be associated with this UM mailbox.

    • Personal operator extension: Use this box to specify the operator extension number for the user. By default, an extension number isn't configured. The length of the extension number can be from 1 through 20 characters. This enables incoming calls for the UM-enabled user to be forwarded to the extension number that you specify in this box.

      You can configure other types of operator extension numbers on dial plans and auto attendants. However, those extensions are generally meant for company-wide receptionists or operators. The personal operator extension setting could be used when an administrative assistant or personal assistant answers incoming calls before they're answered for a particular user.

  5. On the UM Mailbox page, under Other extensions, you can add, change, and view extension numbers for the user.

    • To add an extension number, click Add Add Icon.. On the Add another extension page, use Browse to select the UM dial plan, and then enter the extension number in the Extension number box.

    • To remove an extension number, select the extension number you want to remove, and then click Remove Remove icon..

  6. If you make any changes, click Save.

Use the Shell to configure features for a UM-enabled user

This example disables Play on Phone and missed call notifications, but enables text message (SMS) notifications.


For on-premises and hybrid deployments, when you're integrating Unified Messaging and Lync Server, missed call notifications aren't available to users who have a mailbox located on an Exchange 2007 or Exchange 2010 Mailbox server. A missed call notification is generated when a user disconnects before the call is sent to a Mailbox server.

Set-UMMailbox -Identity -UMEnabled $true -UMMailboxPolicy AdminPolicy -MissedCallNotificationEnabled $false -PlayonPhoneEnabled $false -SMSMessageWaitingNotificationEnabled $true

This example prevents a user from accessing the calendar, but enables access to email when the user is using Outlook Voice Access.

Set-UMMailbox -Identity -UMEnabled $true -UMMailboxPolicy AdminPolicy -Extension 523456 -FAXEnabled $true -TUIAccessToCal $false -TUIAccessToEmail True

This example prevents a user from accessing the calendar and email when the user is using Outlook Voice Access.

Set-UMMailbox -Identity -TUIAccessToCalendarEnabled $false -TUIAccessToEmailEnabled $false

This example prevents a user from creating call answering rules, receiving incoming faxes, and using Outlook Voice Access, but enables Automatic Speech Recognition (ASR).

Set-UMMailbox -Identity -AutomaticSpeechRecognitionEnabled $true -CallAnsweringRulesEnabled $false -FaxEnabled $false -SubscriberAccessEnabled $false

Use the Shell to view a UM-enabled user's properties

This example displays a list of all the UM-enabled mailboxes in the forest in a formatted list.

Get-UMMailbox | Format-List

This example displays the UM mailbox properties for

Get-UMMailbox -Identity


When you're running Exchange 2007 and Exchange 2013 and the user's mailbox is located on an Exchange 2007 Mailbox server, running the Get-UMMailbox cmdlet won't work correctly. To resolve the issue, run the Get-UMMailbox cmdlet from an Exchange 2007 server or a computer running the Exchange 2007 administrative tools.
