Designing and Planning Messaging Services
Have a solid understanding of your network topology The network topology is the basis of
a good messaging environment and thus it is very important to know exactly what is going on
in your organization’s network, as well as where its external connections are. Based on this
evaluation, you must understand what requirements Exchange Server 2007 has on the net-
work topology to prevent problems. Understanding each technical recommendation in this
chapter will help you there.
Get to know the new features of Exchange Server 2007 As Exchange Server 2007 introduces
a couple of new features that might improve your user’s working experience, you need to have a
good understanding of what the benefits of these new features are and of how to plan them into
your overall messaging design. In particular, the Unified Messaging and Edge Transport server
roles offer quite a bit of potential.
Understand how Exchange Server 2007 improves message routing As the routing topic is
key to every messaging system, you must have a thorough understanding of what is improved
by Exchange Server 2007. What aspects of internal and external message routing are different
from previous versions of Exchange? Be sure you understand exactly when you need to define
a hub site and when to define Exchange-specific costs. You should also be able to describe the
term delayed fan-out.
