Microsoft has unveiled the first Service Pack for its Exchange Server 2007 enterprise collaboration platform, and opened a technology preview for the software.

Exchange Server 2007 SP1 features enhancements including support for Windows Server 2008 and Windows Vista, enhanced integration with Microsoft Office Communications Server 2007, improved mobile device management and advanced security technology.

The service pack also includes features designed to provide greater functionality in the Exchange Server 2007 Management Console, and deliver improved disaster recovery capabilities through Standby Continuous Replication.

As part of the technology preview, nearly a million Microsoft Developer Network and TechNet subscribers can download the service pack beta.

Terry Myerson, general manager for Exchange Server at Microsoft, said: "With the new service pack, we have zeroed in on several areas of investment that are important to our customers.

"This includes support for Microsoft's next-generation platforms and improved mobile device management."
