What is Organization in Microsoft Exchange Server?

The root or highest-level administrative unit in Microsoft Exchange Server, which is usually identified by the broadest name that can represent the enterprise’s business - the organization name cannot be changed without reinstalling all servers.

An Exchange organization consists of a number of sites, each of which consists of one or more Exchange servers. Sites are connected by connectors such as a Site Connector or Dynamic RAS Connector.

You can also use other connectors such as the Internet Mail Service Connector or X.400 Connector to provide messaging connectivity between your Exchange organization and a foreign mail system. Examples of such foreign mail systems include the following:

• The collection of Simple Mail Transfer Protocol (SMTP) hosts on the Internet
• A public or private X.400 message-handling system
