One of the first concepts you need to understand when planning an Exchange Server 2007 deployment (even in a lab) is what the server roles are and when to use them. The server roles in Exchange 2007 are:
Mailbox Server
Client Access Server
Hub Transport Server
Edge Transport Server
Unified Messaging Server
In this tutorial, I provide a closer look at each of these server roles and explain its significance in an Exchange Server 2007 design and infrastructure.
