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, click Recipient Configuration.
   
   
2. In the result pane, select the user mailbox that you want to enable for Unified Messaging.
   
   
3. In the action pane, click Enable Unified Messaging.
   
   
4. In the Enable Unified Messaging wizard, on the Introduction page, complete the following fields:
   
   
   • Unified Messaging Mailbox Policy   Use this text field to select the UM mailbox policy that you want to associate with a user's mailbox.
     
     UM mailbox policies define settings such as PIN policies, dialing restrictions, and message text for Unified Messaging messages sent to the user. Each UM-enabled user is required to be associated with at least one UM mailbox policy. However, the UM-enabled user can be associated with only one UM mailbox policy.
     
     
   • Automatically generate PIN to access Outlook Voice Access   Click this button to automatically generate a PIN for the UM-enabled user. This is the default setting. If this option is selected, a PIN is automatically generated based on the PIN policies configured on the UM mailbox policy associated with the recipient. We recommend that you use this setting to help protect the user's PIN.
     
     
   • Manually specify PIN   Click this button to manually specify a PIN that a recipient will use to access the Unified Messaging system.
     
     The PIN must comply with the PIN policy settings configured on the UM mailbox policy associated with this recipient. For example, if the UM mailbox policy is configured to accept only PINs that contain seven or more digits, the PIN you enter in this text box must be at least seven digits.
     
     
   • Require user to reset PIN on first telephone logon   Select this check box to force the user to reset a Unified Messaging PIN when the user accesses the Unified Messaging system from a telephone.
     
     It's a security best practice to force UM-enabled users to change their PIN at their first logon to help protect against unauthorized access to their data and Inbox. This is the default setting.
     
     
5. In the Enable Unified Messaging wizard, on the Extension Configuration page, complete the following fields:
   
   
   • Automatically generated mailbox extension   Click this button if you want the extension number for the user's mailbox to be automatically generated from the telephone number specified in the Active Directory directory service and used to populate the field. By default, this setting is enabled. This option will be unavailable if the user is being associated with a SIP URI or E.164 dial plan.
     
     For the user's extension number to populate this field, you can enter the telephone number in the Business field on the Address and Phone tab in the user properties in the EMC. You can also configure a telephone number for a user by configuring the Telephone number field on the General tab on the user account using Active Directory Users and Computers.
     
     If you select this option, the extension number generated automatically for the user will comply with the number of digits specified for the dial plan with which the UM mailbox policy that you selected is associated. For example, if the dial plan is configured to use 5-digit extension numbers, the Unified Messaging server will take the last 5 digits of the user's telephone number and use those digits to populate this field. UM dial plans are typically configured to have extensions three through seven digits long.
     
     
   • Manually entered mailbox extension   Click this button if you want to manually configure the extension number for the user's mailbox.
     
     If you select this option, you must supply the extension number for the user. If you select this option, you must provide a valid extension number for the user and must match the number of digits specified on the dial plan. You can configure this field to contain a value range of numeric characters or digits from 1 through 20. The typical extension number is from 3 through 7 digits and is configured on the dial plan with which the UM mailbox policy is associated.
     
     If your existing telephony environment includes extension numbers, you must specify a number of digits that matches the number of digits in those extensions. The number of digits that you specify is the default setting after a UM mailbox policy is selected.
     
     
   • Automatically generated SIP resource identifier   Click this button if you want the SIP resource identifier or SIP address for the user's mailbox to be automatically generated. If you have deployed Microsoft Office Communications Server 2007, the user's SIP address is taken from the msRTCSIP-PrimaryUserAddress attribute in Active Directory. If this attribute isn't populated, the user's primary SMTP address will be used for the SIP address. By default, this setting is enabled, for example, tony.smith@contoso.com.
     
     This option is available only if the user that you enable for Unified Messaging is associated with a SIP URI dial plan. This option will be unavailable if you configure a user's mailbox to be associated with an E.164 dial plan.
     
     If you associate a user with a SIP URI dial plan, you must also manually enter a mailbox extension for the user. This extension number is used when users use Outlook Voice Access to access their Exchange 2010 mailbox. The number of digits that you configure in this field must match the number of digits configured on the SIP URI or E.164 dial plan.
     
     This option will not be available if the user is being associated with a telephone extension dial plan.
     
     
   • Manually entered SIP resource identifier   Click this button if you want to manually enter the SIP or E.164 address for the user. This option is available if the user that you enable for Unified Messaging is associated with either a SIP URI or E.164 dial plan. If you deployed Communications Server 2007, the user's SIP address is taken from the msRTCSIP-PrimaryUserAddress attribute in Active Directory. If this attribute isn't populated, the user's primary SMTP address is used for the SIP address, for example, tony.smith@contoso.com. This option isn't available if the user is associated with a telephone extension dial plan.
     
     If you associate the user with an E.164 dial plan, you must manually enter an E.164 address for the user. The number entered must be in the correct E.164 format, for example, +14255551234.
     
     If you associate the user with a SIP or E.164 dial plan, you must also manually enter a mailbox extension number for the user. This extension number is used when users use Outlook Voice Access to access their Exchange 2010 mailbox. The number of digits that you configure in this field must match the number of digits configured on the SIP URI or E.164 dial plan.
     
     
6. On the Enable Unified Messaging page, review your configuration settings. Click Enable to enable the user for Unified Messaging. Click Back to make configuration changes.
   
   
7. On the Completion page, confirm whether the user was successfully enabled for Unified Messaging:
   
   
   • A status of Completed indicates that the wizard completed the task successfully.
     
     
   • A status of Failed indicates that the task wasn't completed. If the task fails, review the summary for an explanation, and then click Back to make any configuration changes.
     
     
8. Click Finish to complete the Enable Unified Messaging wizard.
   
   

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.

This example enables Unified Messaging on the mailbox for tonysmith@contoso.com, sets the extension and PIN for the user, and then assigns a UM mailbox policy named MyUMMailboxPolicy to the user’s mailbox.

	Copy Code
Enable-UMMailbox -Identity tonysmith@contoso.com -UMMailboxPolicy MyUMMailboxPolicy -Extensions 51234 -PIN 5643892 -PINExpired $true

This example enables Unified Messaging on a SIP-enabled mailbox for tonysmith@contoso.com, associates a UM mailbox policy named MyUMMailboxPolicy, and sets the extension number, SIP resource identifier, and PIN for the user.

	Copy Code
Enable-UMMailbox -Identity tonysmith@contoso.com -UMMailboxPolicy MyUMMailboxPolicy -Extensions 51234 -PIN 5643892 -SIPResourceIdentifier "tonysmith@contoso.com" -PINExpired $true
