MS Exchange 2003 Server's strong Application Programming Interface eliminates the technical risk often found with Exchange 5.5 when adding third-party utilities.

- In contrast to the store-and-forward technique utilized by POP3 email environments, Microsoft Exchange Server 2003 uses a central-store architecture that liberates users from reliance on a specific PC or notebook, reduces vulnerability to computer breakdown or viruses, and permits both on-line and off-line email, programmed backup, and sophisticated groupware.
- Exchange Server 2003 has an array of collaboration features that permit teams to increase efficiency by sharing scheduling, address books, messages, and data.
