Microsoft Exchange provides a central location where a user can not only access e-mail but can utilize calendar
information, tasks, notes, journals, and contacts.To access these features within an Exchange Server
environment a user must use a program on their computers such as: Outlook (Windows based PCs) or
Entourage (Macintosh based). An added benefit of Exchange is the ability to access all this information while
away from their desks via a web access method known as Outlook Web Access (OWA).
