Certificate Warning Outlook 2007 --> Exchange 2007

Experts,

I've read many forums and TechNet posts on this topic, but I'm having some issues trying to correct / resolve my issue.

First, let me go over my layout.

I have 2 Exchange Servers, 1 with all the roles, and another that's just a CAS (front end web-server).

The Outlook clients are warning that they're trying to reach mail.domainname.com and that doesn't match what's on the certificate (which is servername.domainname.com).

I know this has 100% to do with the autodiscover stuff that the clients are trying to resolve. For DNS, I have a CNAME for "autodiscover" pointing to servername.domainname.com. - As well as mail.domainname.com is a CNAME pointint to the same server.

In the code block below, here is some output.

Any ideas on how to make the warning go away?

*****          IPUWS          CN=servername.domainname.com

Thanks guys.

Viralrathod, that link you send was great.

I changed the https://url on the autodiscover and other ones using the exchange shell to https://servername.domainname.com and it looks like it resolved my issue.

I swore I saw that link before, which is why my setup was mail.domainname.com - but that's the error my clients were getting, on that exact name. I figured after reading through your post again, that I should at least try it with the way it's setup now.

Seems to be OK.

Thanks.
