With Microsoft Outlook Web Access, users can access data on a Microsoft Exchange Server computer using an Internet browser from a UNIX, Macintosh, or Microsoft Windows-based computer. It provides Web-based public access to Microsoft Exchange Server public folders and the global address list. Registered users can log on to their personal accounts to read private e-mail and send messages. Using Web-based public folder access, an organization can build private and public discussion forums on the Internet and private intranets. Users can publish information on the Internet without converting documents to Hypertext Markup Language (HTML) format.
Microsoft Outlook Web Access works with a user's Web browser, communicating through the Microsoft Internet Information Server (IIS) to provide a client interface to a Microsoft Exchange Server mailbox. Outlook Web Access extends the messaging capabilities of Microsoft Exchange Server through the Internet to the World Wide Web.
