I am completely new to Exchange, having used Google Apps for the past 4 years.
I have created two servers.
One is my DC/DNS server - the domain name is the same as the domain of the website I own with WIX and want to use for my email
The other server is Server 2012 with Exchange 2013 installed. It's up and running. I have configured send connector, found articles for that online.
Main thing I am unsure of is how to verify that I own my domain. I am guessing I create an MX record on the DNS server, but not really sure - any help would be greatly appreciated !
