When a UM-enabled user is locked out of their mailbox because they tried to sign in using an incorrect PIN multiple times or they forgot their PIN, you can use one of the following procedures to reset the user's PIN. When you reset a user's Outlook Voice Access PIN, you can configure Unified Messaging (UM) to automatically generate a PIN or you can manually specify the 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 UM PIN using Outlook or Outlook Web App.

Note:
To access their UM-enabled mailbox, subscribers need to use touchtone, also known as dual tone multi-frequency (DTMF), inputs. Speech recognition isn't available for PIN input.

Use the EMC to reset a Unified Messaging PIN

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "UM mailboxes" entry in the Unified Messaging Permissions topic.

  1. In the console tree, navigate to Recipient Configuration > Mailbox.

  2. In the result pane, select the UM-enabled user's mailbox that you want to reset their PIN for.

  3. In the action pane, under the mailbox name, click Reset Unified Messaging PIN.

  4. Use the Reset Unified Messaging PIN windows to reset the UM-enabled user's PIN:

    • Automatically generate PIN to access Outlook Voice Access   Use this option to automatically generate the PIN that's used by the user to gain access to their mailbox using Outlook Voice Access. By default, this setting is enabled.

      The automatically generated PIN will be sent in an e-mail message to the user's mailbox. After they receive the PIN and sign in to their mailbox, they'll be prompted to change the PIN to a PIN that's more familiar to them.

      Outlook Web App for Microsoft Exchange Server 2010 and Office Outlook 2007 let the user reset their PIN. The PIN is automatically generated based on the PIN policies that are configured on the UM mailbox policy that is associated with the user's mailbox. We recommend that you automatically generate PINs for Outlook Voice Access users.

    • Manually specify PIN   Use this option to manually specify a PIN for an Outlook Voice Access user. By default, this setting is disabled.

      If you specify a PIN for a user, the PIN will be sent in an e-mail message to the user's mailbox. After they receive the PIN and sign in to their mailbox, they can change the PIN by configuring personal options in Outlook Voice Access. However, in Outlook Web App for Exchange 2010 and Outlook 2007, there is no option to manually specify a PIN.

    • Require user to reset PIN at first logon   Use this option to require the user to reset their PIN when they first sign in to Outlook Web App. By default, this option is disabled.

      If you select the option to automatically generate a PIN for a user, you can enable this option to require users to change their PIN when they first sign in to Outlook Voice Access. This helps protect the user's PIN.

  5. Click Apply, and then click OK.

Use the Shell to reset a Unified Messaging PIN
