Email, calendaring, collaboration, and mobility solutions are moving from corporate data centers to service provider networks. Service providers can realize far greater economies of scale than most businesses and deliver higher levels of service to more users at a lower cost; in fact, the fewer the users, the higher cost for each. Concentric Hosted Exchange is a fast, reliable and affordable solution for email, calendaring, collaboration, and mobility based on Microsoft® Exchange Server 2007 Service Pack 1 (SP1) and Microsoft Outlook® 2007. Concentric Hosted Exchange provides all of the benefits of Microsoft Exchange and Outlook 2007 without the up-front infrastructure costs or ongoing overhead.

Email has become something of a critical utility, much like the electricity that powers our offices: it must be available 24 hours a day, it must provide reliable performance, and its cost must be reasonable. However, unlike electrical systems (at least from the user’s perspective), email systems require significant amounts of labor to manage well. Email systems must periodically be upgraded. New hardware must be introduced as organizations migrate to new systems. Security must be maintained and upgraded to protect the system from intrusions. Additional hardware must be deployed to protect against outages that could seriously harm user productivity. Plus, unexpected events, such as spam storms or natural disasters can drive up costs substantially in ways that were not anticipated.
