Messaging management is becoming more difficult thanks to the growing malware threat. At the same time, messaging system administrators are under enormous pressure to push their messaging infrastructures to do more than ever, including archiving messaging content for regulatory compliance, archiving to support legal discovery and for overall litigation support, providing services to a growing body of mobile users, and ensuring continuity by making the messaging system more reliable, and managing policies for message encryption.

The problem caused by viruses, worms and spam continues to build. Zombie networks are generating record levels of spam and viruses and phishing poses a serious and growing threat to personal information that can lead to enormous financial losses. A signature-based approach to virus-detection no longer provides adequate protection. This trend is driving the need for zero-day virus protection.

Hosted solutions, such as those offered by Microsoft® Exchange Hosted Services, can elegantly address the growing array of messaging requirements and threats, and can do so without unnecessarily adding to the cost of current messaging management activities and the complexity of the IT environment.
