Part I: An Overview of Exchange Server 2007
Considering the Exchange
Server 2007 Features
Exchange Server started as a simple mail and calendar program, but over the
years it’s evolved in a number of ways. First, Exchange Server has become
more scalable. You can support more people from a single server, making
multiple server setups less necessary. However, when you need to use
multiple servers, you can do so with less effort.
Second, as with all Microsoft products, Exchange Server 2007 has more features
than previous versions. Microsoft is constantly improving their products by
adding features that sound interesting or that their customers request. To some
extent, the extra features also increase product complexity, so it’s important to
choose the right Exchange Server edition and install only the features you need.
Third, as part of an overall effort by Microsoft, you find Exchange Server 2007
features designed to improve reliability, speed, or security. These features
may not even be visible and you probably wouldn’t know about them unless
Microsoft told you they were there. These features are actually the best
additions to Exchange because they make everyone more productive and
less worried about their data. Table 1-1 provides a description of all three of
these feature classes.

4 Helps you support installations
at the perimeter (edge) of your
network. This server supports
Simple Mail Transport Protocol
(SMTP) routing. It also provides
both antispam and antivirus net-
work for users outside the normal
network environment. Unlike
most parts of Exchange Server,
the Edge Transport server doesn’t
have direct Active Directory
access, but it does support Active
Directory access through the
Active Directory Application
Mode (ADAM). All communica-
tion between the Edge Transport
server and the rest of the network
is encrypted by default.
