So i am trying to get users on the internet (external) to setup outlook using autodiscover. I have created dns cname for autodiscover.domain.tld and this appears to work fine. The question i have is what is outlook looking for on the searching foruser@domain.tld server:

Clik here to view.
This fails from external but works internal. No doubt it is looking on port 443? Is it looking for mail.domain.tld or something else? Looking in dns? Where does it get the info to know what to look for?
