5.	On the Introduction screen, shown in Figure 1, you have to start by selecting a policy. Click Browse and locate the policy you want to apply to the mailbox. Figure 1. UM-enabling a user mailbox.
6.	Under PIN Settings, you can choose the following: Automatically Generate PIN to Access Outlook Voice Access (the default) Manually Specify PIN (and then indicate the PIN) Require the User to Reset PIN at First Telephone Logon
7.	When you are done, click Next.
8.	From the Extension Configuration options, you can provide the following information: Automatically Generated Mailbox Extension— This is grayed out unless you have the Business field on the Address and Phone tab of the user’s properties in the EMC populated with a number or the Telephone Number field on the General tab of the user account in the AD Users and Computers. This option is for a Telephone Extension plan, but not available if you have an SIP URI or E.164 dial plan. Manually Entered Mailbox Extension— With E.164 or SIP, you can provide the extension for the users manually. It must match the number of digits you specify for the dial plan itself. SIP Resource Identifier— Here you can choose Automatically-Generated SIP Resource Identifier or Manually Entered SIP or E.164 Address.
9.	When the settings are configured, click Next.
10.	Review your Configuration Summary, and click Enable if everything checks out fine.
11.	When complete, click Finish.

Note

There is a note within the wizard that reminds us that UM is a premium feature and requires an Exchange Enterprise Client Access License (CAL) to enable it for the mailbox.

PS Note

The cmdlet in the EMS to enable UM for a user’s mailbox is Enable-UMMailbox, but there are lots of different parameters involved. The easiest solution to perform bulk UM enabling is to use the EMC Wizard to enable one user with the proper configuration settings and then when the command completes, click Ctrl+C to copy the exact PowerShell command. Then you can use that (with some tweaks) to enable UM on multiple users.

After a user is enabled, you can enter the user’s Properties and locate the Mailbox Features tab. From here you can select the Unified Messaging option and select the Properties button. This takes you to some of the properties that you can change, as you can see in Figure 2.

Figure 2. UM Properties on the mailbox.

You can change the mailbox policy and UM address (extensions). You can also select or deselect the following checkboxes

• Enable for Automatic Speech Recognition

• Allow UM Calls from Non-users

• Allow the User to Receive Faxes

• Allow Diverted Calls Without a Caller ID to Leave a Message

You can also provide a personal operator extension.
