Making some progress on this.

It seems there is some new, undocumented Autodiscovery schema that MS  
is using. Autodiscovery from Outlook now leads to an autodiscovery  
request hitting the webserver from a Microsoft IP address.  
Interestingly, it is a *.json extension instead of .xml.  Found some  
discussion online and am doing some reverse engineering to hopefully  
get this resolved.
