Disable common PIN patterns for voice mail

 

Applies to: Exchange Server 2013, Exchange Online

Topic Last Modified: 2013-02-22

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:

  • 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.

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

For additional tasks related to Outlook Voice Access PIN security, see PIN security procedures.

  • Estimated time to complete: Less than 1 minute.

  • You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "UM mailbox policies" entry in the Unified Messaging permissions topic.

  • Before you perform these procedures, confirm that a UM dial plan has been created. For detailed steps, see Create a UM dial plan.

  • Before you perform these procedures, confirm that a UM mailbox policy has been created. For detailed steps, see Create a UM mailbox policy.

  • For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard shortcuts in the Exchange admin center.
