This topic explains how to use the Exchange Management Console and the Exchange Management Shell to configure the PIN lifetime. The PIN lifetime is the maximum time that an Outlook Voice Access PIN will be valid for your UM-enabled Microsoft Exchange Server 2007 recipients. The PIN lifetime setting is configured on a UM mailbox policy and applies to all UM-enabled users who are associated with the UM mailbox policy.

When Outlook Voice Access users dial in to a subscriber access number, they are prompted to enter their PIN so that the Unified Messaging system can authenticate them. After they are authenticated, they can access the voice mail, e-mail, calendaring, and personal contact information in their Exchange 2007 mailbox from any telephone.

Several PIN-related settings can be configured on a UM mailbox policy. The PIN Lifetime setting controls the time interval, in days, from the date an Outlook Voice Access user last changed their PIN to the date they will be forced to change their PIN again. The range is 0 through 999, and the default is 60 days. If you enter 0, the user's PIN will not expire. However, we do not recommend that you configure this setting to 0. By configuring this setting to 0, you greatly reduce the security of your network.

Important:
Unified Messaging does not notify the user when their PIN is about to expire.

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 the following:

  • A UM dial plan has been created.

  • A UM mailbox policy has been created.
