The following two URIs MUST be added to the list of possible Autodiscover server URIs:

 http://<Domain>/Autodiscover/Autodiscover.xml
 https://Autodiscover.<Domain>/Autodiscover/Autodiscover.xml
  

If an HTTP POST to either of the above URIs results in an HTTP 302 redirect, then the redirect as found in the location field of the response is added to the list of possible Autodiscover server URIs.
