I was never a huge fan of Microsoft’s® Exchange Server—that is until Exchange2003. Exchange Server 2003 introduced many of the features that I was looking for to be able to considerExchange a good, rock-solid environment for a corporate email solution. Now, with the introduction of ExchangeServer 2007 just around the corner, Microsoft is stepping up to the plate with their best offering to date.Microsoft recently released a public preview of Exchange Server 2007 Beta 2 (previously called Exchange 12)in June 2006 and is shooting for a general availability date of late 2006 or early 2007. Microsoft ExchangeServer 2007 has been designed to meet the tough challenges for a corporate communication solution and pro-vides a rich feature set that users can access through a variety of different interfaces and devices.What’s the Difference?Yes, it is true that Exchange 2007 has kept most of the functionality of its predecessors; however, the imple-mentation of this functionality has been greatly improved and many new features have been added. Whilesome of the changes may be obvious to many administrators, others are not quite as easy to spot with thenaked eye.1. 64-Bit: It’s Time Has ComeSince Exchange Server 4.0, over 10 years ago, Exchange has been operating within the same 32-bit architecture.The messaging environment has evolved into a mission-critical application and demands placed on messagingsystems will continue to grow. Sixty-four-bit servers provide the system architecture to meet these increaseddemands while reducing costs within organizations through server and disk storage consolidations.Exchange Server 2007 has been completely rewritten from the ground up as a 64-bit enhanced application.With the larger addressable memory space, Exchange Server 2007 can utilize more memory, thereby reducingthe required input/output per user (IOPS). This also enables the use of larger disks, as well as lower cost stor-age solutions such as SATA2 drives. Sixty-four-bit should eliminate many of the bottlenecks that have beenseen with previous versions of Exchange Server.2. New Server Role ModelExchange Server 2007 introduces Server Roles, a new concept to organize Exchange services. While Exchange2003 provided a primitive type of server roles called BackEnd and FrontEnd servers, Exchange 2007 breaksthese into smaller, more identifiable roles. Exchange Server 2007 will make the following roles available:Copyright ©2006 Global Knowledge Training LLC. All rights reserved.

Have a lot of Outlook Web Access (OWA) users?Install additional Client Access Servers and use network load balancing. Is SPAM out of control? Install a newEdge Transport Server. You get the idea.3. New and Improved Administration ToolsMicrosoft Windows Applications have always been known for their easy-to-use graphical tools for administra-tion. Exchange Server 2007 takes administration to the next level by offering not only a graphical user interface,but also an extremely powerful command line administration console.The Exchange Management Console (formerly known as the Exchange System Manager) has a new andimproved look and feel, and is based on the newer MMC version 3.0. In addition, the new command lineinterface, called the Exchange Management Shell, provides administrators with a new interface for systemmanagement and can perform every task that can be performed by using Exchange Management Console,plus some. In fact, when a task is performed in the Exchange Management Console, the same command ismade available to the Exchange Management ...
