Server 2007 messaging system.
The company has five offices. The offices are connected by 128-KBps WAN links. A Microsoft Active
Directory site is configured for each office. The messaging system is centralized in the main office.
Mailbox servers, Hub Transport servers, and Client Access Servers are deployed on the internal network
in the main office. Edge Transport servers are deployed on a perimeter network in the main office.
The company plans to deploy Unified Messaging for users in all five offices. The company has the
following requirements:
