Topic Last Modified: 2013-02-22
You can configure the minimum PIN length for your Outlook Voice Access users 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 to access their voice mail, email, calendar, and personal contact information located in their mailbox. However, before they can access their mailbox, they must enter a PIN so they can be authenticated by the voice mail system.
|If you change the minimum PIN length value, existing Outlook Voice Access users will be prompted to enter a new PIN that contains the new minimum number of digits before they can continue. The default is 6.|
