I have an Exchange server where client access and hub transport roles are installed. The autodiscovervirtual directory and client access service autodiscover url are correct, https://exchange.cas.FDQN/autodiscover/autodiscover.xml
. But when I do the Test Email Autoconfiguration test in Outlook 2007, it is trying to access the autodiscover.xml using the external URL. Can you please give some ideas to resolve this issue.
