Exchange Server 2007 Interview Preparation Guide

Microsoft Exchange Server 2007 is the next version of Microsoft Exchange. Microsoft Exchange is the industry’s leading e-mail, calendaring, and unified messaging server. The release of Exchange Server 2007 is closely aligned with the 2007 Microsoft Office release. Together, these products deliver a best-in-class enterprise messaging and collaboration solution.

Exchange 2007 provides built-in protection to keep the e-mail system up and running and protected from outside threats and lets employees work more productively from wherever they are by using a variety of clients. These clients include Microsoft Office Outlook 2007, Microsoft Office Outlook Web Access, and mobile devices. Exchange Server 2007 makes it easier for IT departments to deliver these new capabilities to their organizations by making the messaging environment easier to manage and more cost-efficient.

Outlook 2007 provides the most complete e-mail, calendaring, contacts, and tasks functionality available in an e-mail client that is compatible with Exchange. When Outlook 2007 is used with Exchange Server 2007, users benefit from the new Scheduling Assistant that automates time-consuming meeting and resource scheduling, the ability to plan and customize out-of-office communications, and managed e-mail folders that facilitate compliance with internal and regulatory policies. Outlook 2007 and Exchange Server 2007 also combine to enhance security by offering features that are easy to use and let users confidently send and receive sensitive business communications through e-mail. By enabling the Autodiscover service, you can reduce the complexity of client configuration and reduce administrative costs that are associated with troubleshooting connectivity issues for users.

You can find Exchange Server 2007 product documentation on the Exchange Server 2007 Technical Library Web site, on the Start menu, or by clicking F1 within the product after it has been installed. You can also access product documentation from the Microsoft Exchange Server TechCenter

Customers can purchase the Exchange Enterprise Client Access License (CAL) or the Exchange Standard CAL. The Exchange Enterprise CAL is sold as an add-on to the Exchange Standard CAL. Two server editions will continue to be offered: Exchange Server Enterprise Edition and Exchange Server Standard Edition. You can run either CAL together with either server edition.

In addition to the improvements and new capabilities that are available with the Exchange Standard CAL, the Exchange Enterprise CAL includes Unified Messaging, advanced compliance capabilities, and on-premises and hosted antivirus and anti-spam protection.

Exchange Server 2007 is offered in two server editions: Standard Edition and Enterprise Edition. Exchange Server 2007 Standard Edition is designed to meet the messaging and collaboration needs of small and medium organizations. It may also be appropriate for specific server roles or branch offices. Exchange Server 2007 Enterprise Edition, designed for large enterprise organizations, enables the creation of multiple storage groups and databases.

If you are running 64-bit hardware in your current messaging environment, you may not have to buy additional hardware. However, Exchange 2007 does require hardware and an operating system that are 64-bit. 64-bit hardware provides the system architecture that is required to support the increased memory, storage, and enhanced security requirements in a more cost-effective manner. For more information about how to select the hardware for Exchange 2007

Exchange Server 2007 supports servers that have "x64" processors. Most new servers include processors from Intel and AMD that provide this x64 support. The Intel processors are called Intel Extended Memory 64 Technology (EM64T), and the AMD processors are called AMD64. Exchange Server 2007 does not support Itanium (IA-64) processors.

For the best performance, when an Active Directory organization contains more than 20,000 objects, you should upgrade to 64-bit. Upgrading servers that run Active Directory domain controllers and the global catalog to 64-bit improves the overall performance and scalability of your Exchange Server 2007 environment. However, 32-bit domain controllers are still supported.
Lookup and response times between the Exchange 2007 categorizer and the Active Directory directory service will improve with the use of 64-bit. The size of the Extensible Storage Engine (ESE) database that holds Active Directory can frequently be larger than 3.0 gigabytes (GB). This prevents caching of the contents of the whole database, and therefore increases lookup and response times. By using 64-bit, the available RAM for caching can be increased beyond 4.0 GB. This is large enough to cache the whole ESE database, even for large Active Directory organizations, and will improve Exchange 2007 lookup and response times.
