You can enable or disable common Unified Messaging (UM) PIN patterns for Outlook Voice Access users. If you enable or disable the common PIN patterns setting on a UM mailbox policy, the setting will apply to all UM-enabled users associated with the UM mailbox policy. By default, UM-enabled users can't use common patterns when they create a PIN.

You can configure several PIN-related settings on a UM mailbox policy. The Allow Common PIN 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:

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