I went through the MS Exchange Team blog post http://msexchangeteam.com/archive/2009/10/08/452775.aspx titled “Exchange 2010 is Code Complete and on its way to General Availability”.

It’s nice to hear that Exchange 2010 is Code Complete & it has been sent to early adopters for one final look before its public release. This Release to Manufacturing (RTM) milestone - way to general availability and the launch at Tech·Ed Europe 2009 (http://www.microsoft.com/europe/teched/) in early November. Wow, good job!!
