Topic Last Modified: 2007-07-27

This topic explains how to use the Exchange Management Console and the Exchange Management Shell to prevent UM-enabled users who are associated with a Unified Messaging (UM) dial plan from receiving fax messages. By default, users who are enabled for Unified Messaging and are associated with a UM dial plan can receive fax messages into their Microsoft Exchange Server 2007 Inbox. However, there may be times when you want to prevent users who are associated with a specific UM dial plan from receiving faxes.

If you disable incoming fax message delivery on a UM dial plan, all users who are associated with the dial plan will be prevented from receiving fax messages. You can also prevent all users from receiving fax messages by setting the number of incoming fax calls to 0 on each Unified Messaging server that is associated with a 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.

In addition to preventing all users who are associated with a dial plan from receiving fax messages, you can prevent a single user who is associated with the dial plan from receiving fax messages. To do this, configure the properties for the user by using the Exchange Management Console. If you want to prevent a group of the users who are associated with the dial plan from receiving fax messages, use the Set-UMMailbox cmdlet. For more information about how to enable a user or users to receive fax messages, see How to Enable UM-Enabled Users to Receive Faxes.

importantImportant:
If you disable incoming fax message delivery on a UM dial plan, all users who are associated with the dial plan will be unable to receive fax messages, even if you configure a user's properties to allow fax messages to be received. Enabling or disabling faxing on a UM dial plan will take precedence over the individual user setting that is available when a user is enabled for Unified Messaging.

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 Microsoft Exchange 2007, see Permission Considerations.

Also, before you perform these procedures, confirm that a UM dial plan has been created.

  1. In the console tree of the Exchange Management Console, expand the Organization Configuration node, and then click the Unified Messaging node.

  2. On the UM Dial Plans tab, select the UM dial plan for which you want to prevent UM-enabled users from receiving faxes, and then click Properties in the action pane.

  3. On the dial plan Properties page, on the General tab, clear the check box next to Allow users to receive faxes.

  4. Click OK to save your changes.

  • Run the following command:

    Set-UMDialPlan -Identity MyUMDialPlan -FaxEnabled $false
    

For more information about syntax and parameters, see Set-UMDialplan.
