Microsoft Exchange Server 2003 revolutionized remote business communications by matching the desktop email experience inside a standard web browser via Outlook Web Access (OWA). For system administrators, ensuring high performance, tight security, and proper configuration requires deep familiarity with OWA Web Administration.
