This topic explains how to use the Exchange Management Console and the Exchange Management Shell to prevent a Microsoft Exchange Server 2007 Unified Messaging (UM) user from receiving faxes. By default, when you enable a user for Unified Messaging, the user will receive faxes. However, you can prevent a user from being able to receive faxes after they have been enabled for Unified Messaging.

You can also prevent multiple users from receiving faxes. You do this by configuring the number of incoming fax calls to 0 on each Unified Messaging server that is associated with the dial plan or by disabling delivery of faxes to users who are associated with the UM dial plan. For more information about how to configure the number of incoming fax calls, see How to Modify the Number of Concurrent Fax Calls Setting. For more information about how to prevent users from receiving faxes on a UM dial plan, see How to Prevent UM-Enabled Users from Receiving Faxes.

To perform the following procedures, the account you use must be delegated the Exchange Organization Administrator 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 mailbox policy has been created.

  • A user has been enabled for Unified Messaging.

  • The UM-enabled user is enabled for faxing.

  1. In the console tree of the Exchange Management Console, expand the Recipient Configuration node, and then click the Mailbox node.

  2. In the result pane, select the UM-enabled user's mailbox that you want to modify.

  3. In the action pane, click Properties.

  4. On the Mailbox Features tab, click Unified Messaging, and then click Properties.

  5. On the Unified Messaging Properties page, clear the check box next to Allow the user to receive faxes.

  6. Click OK to save your changes.

  • Run the following command:

    Set-UMMailbox -Identity -FaxEnabled $false
