For most businesses today, e-mail is the mission-critical communications tool that allows their people to produce the best results. This greater reliance on e-mail has increased the number of messages sent and received, the variety of work getting done, and even the speed of business itself. Amid this change, employee expectations have also evolved. Today, employees look for rich, efficient access—to e-mail, calendars, attachments, contacts, and more—no matter where they are or what type of device they are using.

For IT professionals, delivering a messaging system that addresses these needs must be balanced against other requirements such as security and cost. Enterprise security requirements have become more complex as the demand and use for e-mail has increased. Today, IT departments must contend with e-mail security threats that are wide ranging: continually evolving spam and viruses, noncompliance risks, the vulnerability of e-mail to interception and tampering, in addition to the potential harmful effects of natural and man-made disasters.

While security is clearly a priority, IT is ever cognizant of the need to manage cost. Time, money, and resource constraints are a fact of life as IT is made accountable to do more with less. As a result, IT professionals look for a messaging system that addresses both enterprise and employee needs while also being cost-effective to deploy and manage.

Microsoft Exchange Server has been designed specifically to meet these challenges and address the needs of the different groups who have a stake in the messaging system. The new capabilities of Microsoft Exchange Server 2007 deliver the advanced protection your company demands, the anywhere access your people want, and the operational efficiency you, in IT, need.
