Mailbox policy objects control unified messaging settings and security for users. The UM mailbox policy objects can be found in the Exchange Management Console on the UM Mailbox Policies tab of the Organization, Unified Messaging container.
These settings include the following:
• Maximum greeting duration
• Message text for UM-generated messages to users
• PIN policies
• Dialing restrictions
Mailbox policies are created to control security and provide customized messages to users. For example, in Figure 20.6, the SFO Mailbox Policy 1 is a general user policy with default PIN settings that require a minimum of six characters. The second policy, SFO Mailbox Policy 2, is for executives with higher security requirements and more secure PIN settings that require a minimum of 10 characters.
The UM mailbox policy is associated with one UM dial plan, but dial plans can be associated with multiple mailbox policies. This enables the dial plan to be associated to the users associated with the mailbox policy. Each user is associated with one UM mailbox policy object, but many users can be associated with a single mailbox policy object.
