Does Azure support Exchange 2013 DAGs?
ANSWER: Not as of Feb 20, 2014. Exchange 2013 is not supported. So no Exchange = no DAGs. Trick question. Microsoft tried to get an Exchange witness server into Azure, but it ran into technical issues as noted here. http://blogs.technet.com/b/exchange/archive/2013/08/07/database-availability-groups-and-windows-azure.aspx
