We have a Exchange server setup on mail.domain.com,  and autodiscover is working fine with a SRV record in the DNS, but since iphone does not support autodiscover via SRV Record, we had to setup a CNAME "autodiscover.domain.com"and point that to "mail.domain.com" , iPhone autodiscover works fine after that. But since then outlook desktop client keeps prompting certificate name mismatch warnings ( as it now wants a Certificate for autodiscover.domain.com).  is it possible to fix this without buying a new SAN certificate? 

Thanks!
