I have been a Program Manager in Exchange for the last 6 years.  I had the opportunity to work on several technologies, from the inner beauty of "Content Conversion" to the far reaching "Transport and Routing infrastructure", including our Edge services.  In the recent couple of years I have been working on the Exchange device access functionalities (Exchange Server ActiveSync).  You may have seen me at one of the big conferences... the Exchange guy with a goatee and an Italian accent!
