If you look closely at this Exchange Server roadmap slide, presented by Microsoft execs at the IT Forum in Barcelona, you might notice a slight hedge in Microsoft's final Exchange 12 ship date projection. Microsoft execs announced earlier this year that Exchange 12 would ship in 2006. Now Microsoft is back to saying to expect Exchange 12 in late 2006 or early 2007. Officials also are promising some new "E12-optimized services" in the late 2006/early 2007 timeframe.
