Exchange Server, the Microsoft messaging and collaboration server, is software that runs on servers that enables you to send and receive electronic mail and other forms of interactive communication through computer networks. Designed to interoperate with a software client application such as Microsoft Outlook, Exchange Server also interoperates with Outlook Express and other e-mail client applications. Meet the requirements for small and large organizations and get easy administration, support, and reliability with Exchange Server. Readily available deployment and support tools also make Exchange Server easy to manage.

Exchange Server offers you integrated collaborative messaging features such as scheduling, contact, and task management capabilities. Exchange Server 2003 runs on Microsoft Windows Server 2003 and Microsoft Windows 2000 Server operating systems. Microsoft Office Outlook 2003 runs on Windows-based computers and communicates with the server running Exchange Server through the MAPI protocol that includes powerful messaging and rich collaboration capabilities. Exchange Server also accommodates other client access through its support for Post Office Protocol 3 (POP3) and Internet Message Access Protocol 4 (IMAP4) protocols as well as support for Simple Mail Transfer Protocol (SMTP). Microsoft Outlook Web Access, a service in Exchange Server, accommodates what are known as thin clients (Web browser–based access clients).
