In addition, Microsoft released a beta version of Forefront Security for Exchange Server, the first product in its new Forefront line of enterprise security software. Forefront Security for Exchange Server, the next generation of Microsoft Antigen for Exchange, integrates with Exchange to provide protection against viruses, worms and spam.
Both products are scheduled for general availability toward the end of this year or in early 2007.
The new version of Microsoft's Exchange messaging and collaboration server software includes security, performance, data protection and manageability updates. Performance optimization changes can trim storage costs by more than 60 percent, Terry Myerson, Exchange Server group general manager at Microsoft, wrote in a blog post announcing the new beta.
Other new features focus on mobile users, allowing them to search e-mail plus handle documents and meeting requests more effectively. New compliance features help organizations automatically enforce e-mail retention rules and other regulatory policies, and new continuous replication tools aim to reduce the time and cost of recovering from a data loss.
