I'm having an issue where externally we are getting weird results with our autodiscover.
When we try to create a new Outlook account externally, it gives a certificate error and points to some wrong URL/cert that it wants to pull down. I'm assuming this is because its trying to go to http://mydomain.com/AutoDiscover but our @ is pointing to our website host.
So I created an autodiscover.mydomain.com and I also created a SRV record which points at autodiscover.mydomain.com which points to the same IP as our mail.mydomain.com
When I do the tests at testexchangeconnectivity.com - it passes but it does fail the first step at http://mydomain.com/autodiscover - which is giving the same exact result that we're seeing on outlook clients.
what am i missing....
