Microsoft exchange server, version and system requirement

Exchange is a popular Microsoft messaging system that includes a mail server, an e-mail program (e-mail client), and groupware applications. Designed for use in a business setting, the Exchange server is often used in conjunction with Microsoft Outlook to take advantage of Outlook's collaborative features, such as the ability to share calendars and contact lists.

What is Outlook Web Access?

Outlook Web Access (OWA) is a form of webmail for Exchange Servers. OWA allows someone with an Exchange Server account to connect with a web browser to send and receive his email, check his calendar and view his contacts list. It provides basic Exchange Server service while providing easy to use access through any web browser. It is ideal for someone traveling or needing to access work email from home where Entourage is not available.
