Outlook 2013 Certificate Error

I'm in the process of moving mailboxes from one Exchange 2010 server to another Exchange 2010 server.  

I set up a CAS array object.

http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_28189035.html

The issue I'm having now is that I get a warning upon launhcing Outlook that states "The-name-on-the-security-certificate-is-invalid-or-does-not-match-the-name-of-the-site".

Where can I start to troubleshoot this?

It appears my AutoDiscoverServiceInternalUri values do not match. I'm adjusting this and will see what happens.

I adjusted this. It removed one error. Now I'm getting an expired cert error. Both servers have matching certs that are not expired. It's our RapidSSL cert. I'm still looking around.

Where can I look to find the expired cert? I tried the MMC and the registry.

Certificates are stored on the server only.
You probably do not have the host names set up correctly in Exchange.
Refer to my article on this process: http://semb.ee/hostnames

RapidSSL don't do UC type certificates unless something has changed, which means you probably have a single name or wildcard SSL certificate. That will almost certainly mean split DNS will need to be used.

Do ensure that you are NOT using the CAS Array address for anything other than the CAS Array - so the host name should be unique to that task.

I am doing split DNS and I have a wildcard cert. The error is for a cert for www. Which we don't manage so I don't understand how Outlook is asking for it. The CAS array object is unique to it's task. Simply a pointer so I can flip a DNS record on the back end.

One of your URLs must be wrong, or Outlook is unable to connect to it and it is accessing an external web host. Going through my article as I have outlined above will fix that in most cases.
