Exchange Server 2007 Features Removed from Exchange 2010

that will be transitioning from Exchange Server 2007 to Exchange Server 2010. A number of
features have been removed from Exchange since Exchange Server 2007; this list is in a ddition

Clearing Up Some Confusion
We mentioned earlier that Exchange has certainly been hyped a lot during the design and
beta-testing process. This has generated a lot of buzz in the information technology (IT)
industry, but this buzz has also generated a lot of confusion and some misinformation. We
want to take this opportunity to clear up some of this confusion by answering a few of the
common questions that have generated misconceptions about Exchange 2010.
Do I have to have three or four separate servers to run each of the server roles? In a small
environment, a single server can host all four primary server roles (Mailbox, Client Access,
Hub Transport, and Unified Messaging), though Microsoft recommends against hosting the
Unified Messaging role on the same server. Unlike Exchange Server 2007, an Exchange 2010
server can host the Mailbox, Client Access, Hub Transport, and Unified Messaging roles. The
Edge Transport role must be installed on a separate server.
Is there a 32-bit version of Exchange? No, no 32-bit version of Exchange 2010 is available.
Is the Edge Transport server required? No, Edge Transport servers are not required. You
can use any third-party message hygiene system in your perimeter network, or you can direct
inbound and outbound mail through your Hub Transport servers, or both.
Does Exchange 2010 use a SQL database for mailboxes and public folders? Although there
has been debate for years about using SQL Server for the Exchange databases, Exchange 2010
uses the Extensible Storage Engine (ESE), also known as the JET database engine.
Is EMS knowledge required? Do I have to learn scripting? Most common administrative
tasks can be performed through the EMC graphical interface. Command-line management and
