Enable or Disable Common PIN Patterns on a UM Mailbox Policy

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

Topic Last Modified: 2012-07-23

You can enable or disable common Unified Messaging (UM) PIN patterns for Outlook Voice Access users in Microsoft Exchange Server 2010. 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 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:

Sequential numbers These are PIN values that include only consecutive numbers. Examples of consecutive numbers for a PIN are 1234 and 65432.
Repeated numbers These are PIN values that include only repeated numbers. Examples of repeated numbers are 11111 and 22222.
Suffix of mailbox extension These are PIN values that include the suffix of a user's mailbox extension. For example, if a user's mailbox extension is 36697, the user's PIN cannot be 3669712.

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