Microsoft released Exchange 12 today to 1,400 testers. This is going to be the next version of the mail/communication server to be released around the same time as Microsoft Office 12. The next beta will come in the second quarter of 2006 and the final release is expected in the third quarter of 2006. Of course any predictions by Microsoft are never very accurate so plan on the first quarter of 2007 at the earliest. New changes include five user selectable server roles and more unified inbox capabilities.
