10 Things About Microsoft Exchange 2007

Exchange 2007 is the latest soon-to-be-released version of Microsoft’s flagship messaging product. As with any new software release many new features have been introduced to assist, in this case, the administrator in the performance of their jobs. The purpose of this article is to introduce future adopters of Exchange 2007 to some of the changes in the new product.

1 Server Roles: With Exchange 2007 Microsoft has introduced the concept of roles in order to make deployment and management easier as well deal with security. In 2007 an administrator can choose the roles that they need to deploy in order to accomplish their specific goals and just install those roles. Have a small business with one site? Just install the Mailbox Server and Hub Transport role. Need that extra layer of message filtering between your company and the outside world? Deploy an Edge Transport server in your network perimeter. All server roles, save the Edge Transport Role, can be deployed on a single server.


2 Exchange Management Shell: In Exchange 2007 a new feature named the “Exchange Management Shell” has been introduced to assist administrators with various maintenance tasks. The EMS is similar to the Windows Command prompt, but much more robust as it is built on the power .NET technologies and Exchange foundation. With EMS administrators can write scripts to automate repetitive tasks instead of relying on the console to execute such tasks. EMS offers a powerful interface to Exchange as well as Active Directory support.


3 Exchange Management Console: The EMC is a replacement for the Exchange System Manager or ESM that has been a staple of Microsoft Exchange for several releases. The EMC offers a much improved and streamlined GUI over previous releases Exchange allowing administrators to perform the tasks that they need to carry out with fewer mouse clicks than ever before.


4 Unified Messaging: With Exchange 2007 Microsoft is offering improved integration with other forms of messaging in the Enterprise, namely voicemail and fax systems. By deploying the Unified Messaging Server role on Exchange Servers a company can deliver voicemail and faxes directly to a users inbox for retrieval from most devices including mobile devices.


5 Improved Availability: By leveraging the power of LCR and CCR organizations can keep their messaging systems online and available much more reliably than ever before. LCR or Local Continuous Replication allows for the creation of a continually updated copy of the production database on another physical volume on the server. CCR or Clustered Continuous Replication extends this concept by storing a copy of the production database on a different physical server altogether. With both technologies administrators can now bring a server up faster in the event of a failure by using a relatively switch-over process.


6 Autodiscover: By enabling the Autodiscover feature administrators can now simplify the configuration of messaging clients. In Exchange 2007 enabling the Autodiscover feature allows users to configure their email client by simply providing a username, email address and password which Exchange uses to locate the user’s mail server and configure the client; users no longer need to memorize or look up the correct mail server.


7 Spam Controls: To deal with the ever increasing amounts of spam Exchange 2007 includes controls out-of-the-box for the reduction spam. The new Smartscreen technology uses administrator configurable rules and builtin Bayesian filtering to reduce the overall threat of spam.


8 Improved Database Performance: Underneath the hood Exchange 2007 sports a greatly improved database architecture which results in large performance increases. Exchange has a smaller database size than previous versions of the product as well as a different structure that improves performance.


9 Routing Groups: Routing Groups have been eliminated in their previous form moving towards a greatly improved architecture in Exchange 2007. In prior versions of Exchange Routing Groups were used to control the flow of messages between different locations in Exchange 2007 Active Directory Sites are used in favor of the previous setup.


10 64-Bit Architecture: In Exchange 2007 a major change has occurred in the overall architecture of the product, namely the shift to 64-Bit shift. 2007 will require a 64-Bit Windows 2003 Server and 64-Bit Hardware to be installed, 32-Bit versions of Exchange will only be available for training and testing and will be unsupported in a “Live” environment. The shift to a 64-Bit model results in substantial performance increases such as faster disk access and greater amounts of physical memory.


While this list represents some of the bigger changes in Exchange 2007 it still only represents a small fraction of the improvements in the product. Please visit www.microsoft.com/exchange for additional info.
