This topic explains how to use the Exchange Management Console and the Exchange Management Shell to reset a PIN for an existing mail-enabled Microsoft Exchange Server 2007 recipient who is currently enabled for Unified Messaging (UM).

Note:
To access their UM-enabled mailbox, subscribers must use touchtone, also known as dual tone multi-frequency (DTMF), inputs. Speech recognition is not enabled for PIN input.

When a UM-enabled user is locked out of their mailbox because they tried to log on by using an incorrect PIN multiple times or forgets their PIN, you can use one of the following procedures to reset the user's PIN. The new PIN is e-mailed to the user. If you prefer, you can specify additional PIN options when resetting the user's PIN. Users can also reset their Unified Messaging PIN by using Outlook 2007 or Exchange 2007 Outlook Web Access. For more information about the additional options that you can configure when you reset the user's PIN, see Recipient Configuration > Mailbox > Reset Unified Messaging PIN.

Important:
When a UM-enabled user is resetting their PIN for Unified Messaging by using Outlook Voice Access, there is the potential for the user's PIN to be compromised. This can occur because the data that contains the PIN for the UM-enabled user may be transmitted over less secure telephone networks, such as copper-based telephone networks or cellular (wireless) networks.

Before You Begin

To perform this procedure, the account you use must be delegated the Exchange Recipient Administrator role.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 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.

  • The existing Exchange 2007 recipient has an Exchange 2007 mailbox.

  • The existing Exchange 2007 recipient is currently enabled for Unified Messaging.

Procedure

To use the Exchange Management Console to reset a UM user's PIN

  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, click to select the UM user. This is the user for which you want to reset the UM PIN.

  3. In the action pane, under the user's mailbox section, click the Reset Unified Messaging PIN option.

  4. In the Reset Unified Messaging PIN dialog box, click OK to reset the UM PIN.

To use the Exchange Management Shell to reset a UM user's PIN

  • Run the following command:

    Copy Code 
    Set-UMMailboxPIN  -Identity tony@contoso.com
