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