Introduction to Exchange Server 2010

Exchange Server 2010 is one of the most functional messaging systems on the market, and the most popular messaging system used in organizations. When most people think of electronic messages, they first think of e-mail, but an electric messaging system can do more than just deliver e-mail. The term electronic messaging system describes a more generalized process that can be used to deliver many different types of information to many different locations. A messaging system has several specific characteristics. First, it involves the participation of at least two parties: the sender and one or more recipient. Second, when a sender dispatches a message, the sender can count on the message being delivered.

There are two types of messaging system:

1. Shared-filed system

2. Client/ Server system.

1. A shared-file email system, works fairly simple. A messaging server contains a shared folder (a mailbox) for each user of the system.

2. An exchange-based system is a form of client/server system, this type of the system is referred to as an active system because the server takes a much more active role than the server in a shared-file system.

To provide these services, exchange server 2010 is typically installed on more powerful server machines than those used for shared-file messaging system, which means that a client/server system such as exchange server is inherently more scalable than a shared-file system.

Exchange server can also provide a higher level of security, reliability, and scalability than a simple shared-file messaging system can.
