This topic explains how to use the Exchange Management Console and the Exchange Management Shell to enable or disable non-delivery reports (NDRs) to be sent when a voice mail message cannot be submitted. By default, when Unified Messaging submits a voice mail message, it will not request that an NDR be sent if the voice message cannot be delivered to its intended recipient. NDRs can be useful in locating and resolving voice message delivery failures. To enable NDRs to be sent, you must first configure the UM dial plan.

If NDRs have not been enabled, an NDR will not be sent if voice message delivery fails. If you want an NDR to be sent when a message is not delivered, you must enable NDRs on the dial plan and then associate the "Microsoft Exchange" recipient with a Microsoft Exchange Server 2007 mailbox. If you do not associate a mailbox with the "Microsoft Exchange" recipient, an NDR will not be sent because a mailbox does not exist for the "Microsoft Exchange" recipient. To associate the "Microsoft Exchange" recipient with a mailbox, use the Set-Organizationconfig cmdlet together with the –MicrosoftExchangeRecipientReplyRecipient parameter. For more information about the Set-Organizationconfig cmdlet, see Set-OrganizationConfig.

Before You Begin

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 that a UM dial plan has been created.


To use the Exchange Management Console to enable or disable NDRs

  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 that you want to manage, and then click Properties in the action pane.

  3. On the dial plan Properties page, under the General tab, select the check box next to Send a non-delivery report if message delivery fails, or clear the check box if you do not want to send NDRs.

  4. Click OK to save your changes.

To use the Exchange Management Shell to enable or disable NDRs

  • Run the following command:

    Copy Code
    Set-UMDialPlan -Indentity MyDialPlan -NDREnabled $true

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