I installed Exchange 2013 into the environment (Exchange 2010 SP3) and left it at that (ie no additional config). I noticed Outlook 2010 client connected to Exchange 2013 somehow (it got a cert warning). Why would Outlook connect to the new
Exchange 2013 server like that? Although I enabled Outlook Anywhere, it is not trying RPC/HTTP first, but rather RPC/TCP.
