domain name system - DNS conflict with Exchange mail server

We have a client whose website we host, and it is creating a conflict with their Exchange mail server. Exchange's Autodiscover URL is reporting back the wrong IP.




The URL in question is https://clientdomain.com:443/autodiscover/autodiscover.xml, and the client's public DNS provider has MX.clientdomain.com and Autodiscover.clientdomain.com pointing to their mail server.



In this instance would it be better to alter our DNS server to point to their IPs, or to set up an XML file at the /autodiscover/ path?
