Server delivers superior scalability and performance.
The Boeing Company, among other Exchange 2000 customers, already experience 99.97 percent uptime even without using high-availability solutions such as clustering. This exceeds the design goal for Domino R5 that was to achieve 99.6 percent uptime. Exchange Server 5.5 provides faster e-mail message delivery. Its maximum message throughput was up to 277 percent higher than that of Domino R5. Exchange 5.5 reduces system delays and increases user productivity.
