    I have an SBS 2011 server with Exchange 2010. Several remote users connect using RPC over HTTPS in Outlook 2003. When I installed the server, I purchased a single-domain SSL certificate from GoDaddy so the remote users would not have to install the self-signed certificate.

    Now I am replacing one of the remote computers and have gone from Outlook 2007 to Outlook 2013. I get a security alert for autodiscover.mydomain.com that the name on the security certificate is invalid.

    I went into the DNS panel where the domain is hosted and tried creating an CNAME record ‘autodiscover’ that resolved to mail.mydomain.com but this did not fix the problem. Next I created an SRV record _autodiscover _tcp that pointed to mail.mydomain.com but I am still getting the security alert.

    Is there an easy fix for this or do I have to purchase a SANS certificate? Because there are not a lot of remote users involved, would it be less expensive to uninstall the GoDaddy SSL and just install and use the self-signed certificate on the remote computers?

    Our OWA address is h t t p s ://mail.mydomain.com

    Thanks
