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 . 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 .
     
     
6. If you make any changes, click Save.
   
   

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

Note:
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 tony@contoso.com -UMEnabled $true -UMMailboxPolicy AdminPolicy -MissedCallNotificationEnabled $false -PlayonPhoneEnabled $false -SMSMessageWaitingNotificationEnabled $true

Important:
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.
