Table 1-3 shows that you must have a combined CAL and volume licensing to
obtain every feature. Of course, the question is whether you really need every
feature for your organization. In most cases, the answer is no, so you need to
analyze your requirements carefully before you make a purchase.
You have a final issue to consider before you decide which edition of
Exchange Server to obtain. One of the potential hidden problems for admin-
istrators is determining how to license Exchange Server. The CAL you obtain
will provide either per-device or per-user licensing.
Obtaining a trial version
Choosing e-mail and time management soft-
ware isn’t something you can do quickly or
without testing things out. Fortunately, you can
obtain a 120-day evaluation copy of Exchange
Server 2007 SP1 for your server from http://
technet.microsoft.com/en-us/
bb736128.aspx. The download doesn’t
require a lot of time. After you download the
trial version, you can install it using the proce-
dures in Chapter 2 and configure it using the
resources in the rest of the book, just as you
would with a purchased version. The only limi-
tation is that you won’t want to configure the
server with production data that you intend to
keep.
