Definition of Outlook Web Access in The Network Encyclopedia.

What is Outlook Web Access?

A component of Microsoft Exchange Server that works with Internet Information Server (IIS) version 4 and Active Server Pages (ASP) technology to allow Exchange users to access their e-mail, address books, and public folder content using a standard Web browser such as Microsoft Internet Explorer.

More generally, Microsoft Outlook Web Access allows administrators to publish Exchange services on the Web. It uses Hypertext Transfer Protocol (HTTP) on the client side and remote procedure calls (RPCs) on the server side.
