Don't have this in your DNS if you are using SRV records: CNAME

CNAME is DNS only, it doesn't change the host name that the client connects to, so you get the SSL warning. should NOT resolve on the internet at all if you are using SRV records.

I have removed the SRV record but same warning
Simon Butler (Sembee)ConsultantCommented:
That wasn't what I said to do.
I said to remove the CNAME.

By leaving the CNAME in place, all you are doing is pointing DNS traffic to the other host. It does NOT change the host name that the client connects to. Unless you have Autodiscover for that additional domain in the certificate (unlikely as you are using other methods) then you will get the warning.

The only way you can use HTTP redirect is by having the web site on its own unique IP address that does NOT have a binding to HTTPS on it, so that the client is unable to make a connection to 
If you only have a single address for the server then you cannot use the HTTP redirect method and must use SRV records.
