This topic explains how to use the Exchange Management Console and the Exchange Management Shell to enable or disable common Microsoft Exchange Server 2007 Unified Messaging PIN patterns for Outlook Voice Access users. You can enable or disable the common PIN patterns setting on a UM mailbox policy and it will apply 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.

There are several PIN-related settings that can be configured on a UM mailbox policy. The Allow Common Patterns setting is used to allow or prevent the use of common number patterns when users create a PIN. By default, this setting is disabled and prevents users from using the following number patterns:

If the Allow Common Patterns setting is enabled, only the suffix of the mailbox extension will be rejected.
