Use the Enable Unified Messaging Wizard to enable an existing Microsoft Exchange Server 2007 user's mailbox for Unified Messaging. After you successfully enable the user's mailbox for Unified Messaging, UM servers that are associated with the UM dial plan that the user is associated with will accept incoming calls for the extension number that is configured for the user. You can configure this extension number automatically or manually by using the Enable Unified Messaging Wizard. An extension number is required for each UM-enabled user. The extension number must be the correct number of digits, as specified in the UM dial plan for the UM Mailbox policy.

After a mailbox-enabled recipient is enabled for Unified Messaging, you should perform the following tasks:

To enable a user for Unified Messaging by using the Enable Unified Messaging wizard, on the Enable Unified Messaging page, complete the following information:

Unified Messaging Mailbox Policy
  • Use this text field to select the Unified Messaging 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 that are 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.

  • You must create the UM mailbox policy before you enable Unified Messaging for a user's mailbox.

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 Active Directory and used to populate the field. This setting is enabled by default.

  • For the user's extension number to populate this field, you can enter the telephone number in the Business field on Address and Phone tab in the user properties in the Exchange Management Console. You can also configure a telephone number for a user by configuring the Telephone number field on the General tab on the user account by using Active Directory Users and Computers.

  • If you select this option, the extension number that is generated automatically for the user will comply with the number of digits that is specified for the dial plan with which the UM mailbox policy that you selected is associated. For example, if the dial plan is configured with 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 that are three to 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 to 20. The typical extension number is from three to seven digits long and is configured on the dial plan with which the UM mailbox policy is associated.

  • If your existing telephony environment includes extension numbers, you should 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 generate PIN to access Unified Messaging
  • 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 that are configured on the UM mailbox policy that is associated with the recipient.

  • It is generally recommended that you use this setting to help protect the user's PIN.

  • The first time that the user logs on to their mailbox using Outlook Voice Access, they will be prompted to change their PIN.

Specify PIN to access Unified Messaging
  • 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 that are configured on the UM mailbox policy that is associated with this recipient. For example, if the UM mailbox policy is configured to only accept PINs that contain seven or more digits, the PIN you enter in this text box must be at least seven digits long.

Require user to reset PIN on first telephone logon
  • Use this check box to force the user to reset their Unified Messaging PIN when they access the Unified Messaging system from a telephone.

  • It is a security best practice to force a UM-enabled user to change their PIN at their first logon to help protect against unauthorized access to their data and Inbox. This is the default setting.

After you complete the fields on the Enable Unified Messaging page of the Enable Unified Messaging Wizard, click Enable to enable Unified Messaging on the user's mailbox.
