You can configure the minimum PIN length for your mail-enabled recipients in Microsoft Exchange Server 2010 who are enabled for Unified Messaging (UM). The PIN settings that you configure on a UM mailbox policy will apply to all UM-enabled users associated with the UM mailbox policy.

Outlook Voice Access is used by UM-enabled users so that they can access their voice mail, e-mail, calendar, and personal contact information located in their Exchange 2010 mailbox. However, before they can access their mailbox, they must enter a PIN so they can be authenticated by the system.

Note:
If you make a change to the minimum PIN length value, existing subscribers will be prompted to enter a new PIN that contains the new minimum number of digits before they can continue.
