Preparing for the Exchange Installation
Features That Have Been De-emphasized
The following key features and functionality have been de-emphasized in Exchange
Server 2007:
Public folders
ßN
: Public folders are no longer required in a clean installation of Exchange
Server 2007. In previous versions of Exchange Server, public folders contained critical
system data such as the Offline Address Book (OAB) and free/busy calendaring data.
This is no longer the case, because no system data is stored in public folders in a pure
Exchange 2007 environment. Public folders, however, are still supported in Exchange
Server 2007, although Microsoft recommends moving to SharePoint Portal Server or
another product for those items that previously were stored in public folders. It’s expected
that public folders (which were initially advertised as not being supported in Exchange
Server 2007) will not be supported in a future release of Exchange Server. Microsoft’s
official support policy says that they will support Public Folders in Exchange 2007
until 2016. I’ll cover public folders in Exchange Server 2007 in Chapter 6, “Configuring
and Managing Public Folders.”
Exchange Server 2003 virus scanning API (VSAPI)
ßN
: Although Exchange Server 2007
still supports the VSAPI, its role is being de-emphasized because Microsoft has started
to integrate antivirus controls at the transport layer. We’ll cover antivirus controls in
Exchange Server 2007 in Chapter 7.

Preparing the Infrastructure for
Exchange Server 2007 Deployment
If you are planning to deploy Exchange Server 2007, you need to make sure that all of the
requirements are met. We have covered many of these requirements over the last few sections in
this chapter. These requirements and limitations encompass much of what you need to know to
be successful in preparing to install Exchange Server 2007, and to succeed on the exam.
The schema master must be running Windows Server 2003 Service Pack 1 or later.
ßN
A global catalog running Windows Server 2003 Service Pack 1 or later must be avail-
ßN
able in each Active Directory site into which Exchange will be deployed. This cannot
be a Windows Server 2008 read-only domain controller.
The Active Directory forest must be set to at least the Windows Server 2000 functional
ßN
level; however, if cross-forest free/busy information will be shared or forest-to-forest dele-
gation is used, the forest must be set to at least the Windows Server 2003 functional level.
