Microsoft Exchange Server 2007 will reach end of support on April 11, 2017. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.


Applies to: Exchange Server 2007, Exchange Server 2007 SP1, Exchange Server 2007 SP2, Exchange Server 2007 SP3

This topic explains how to use the Exchange Management Console or the Exchange Management Shell to enable a Microsoft Exchange Server 2007 Unified Messaging (UM) auto attendant. By default, when a UM auto attendant is created, the status of the UM auto attendant is set to enabled. After you create the UM auto attendant, you can control its status by using the status variable. If the status of a UM auto attendant is disabled, you will have to enable the UM auto attendant to allow it to answer incoming calls.

Before You Begin

To perform this procedure, the account you use must be delegated the Exchange Organization Administrators role.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.

Also, before you perform these procedures, confirm the following:

  • A UM dial plan has been created.

  • A UM auto attendant has been created and the status is set to disabled.


To use the Exchange Management Console to enable a UM auto attendant

  1. In the console tree of the Exchange Management Console, click the Organizational Configuration node.

  2. In the console tree, click Unified Messaging.

  3. In the work pane, click the UM Auto Attendants tab.

  4. In the work pane, select the auto attendant object that you want to enable.

  5. In the action pane, click Enable.

To use the Exchange Management Shell to enable a UM auto attendant

  • Run the following command:

    Enable-UMAutoAttendant -Identity MyUMAutoAttendant
