How do I use microsoft exchange?

The new version, Exchange 2007, is scheduled to be released on DVD in late Nov 2006 to business customers as part of the Vista, Office 2007, SharePoint 2007 wave. It is to include voice mail integration, better search and support for Web services. The company also announced that the new version would run on 64-bit version of Windows only, pointing out the substantial performance benefits that 64-bit brings to the product. However, companies currently running Exchange on 32-bit hardware will be forced to replace or add hardware if they wish to upgrade to the new version. Even those companies that are currently running Exchange on 64-bit capable hardware will still need to upgrade their server operating system simultaneously with the Exchange 2007 upgrade. This is because Exchange 2003 cannot be installed on Windows 2003 64-bit.
