We are trying to setup autodiscover on our exchange server and are having issues. test exchange remote connectivity is failing on the last step. I have checked internal and external urls, rebuild the autodiscover virtual directory and when we go to the web address externally it asked for credentials and then displeys the error 600 which I believe is correct.
Any ideas? See output form connectivity tester below.
