Invalid SSL certificate

I installed a UCC certificate from GoDaddy on my Exchange 2010. After I installed it on the Exchange sever  our 2007 Outlook users get this error when they open Outllook:
 "The name of the security certificate is invalid or does not match the name of the site"

I googled the error and tried to follow the suggestions but was not sure of the steps in some of the links. I am new to Exchange 2010 and command line. I am trying to find a link that is not so cryptic

What names do you have on your cert? Which one is it saying doesn't match the certificate? Change the internal URLs to point at a name on your cert that resolves to the internal IP of your CAS server.

The names you should have on your UCC Certificate are as follows:

mail.domain.com (or whatever you want to use)

If you don't have those names in your certificate, please re-key the certificate and include them, then your error should go away.

Yes I have to change the internal URLs according to the info I have found researching the error I am just not quite clear on how to do it being that I am new to Exchange 2010 and powershell.

Those are the names I have on my certificate. If I run the " Get-ExchangeCertificate" command I only see IP and WS as the only service assciated with the thumb print. When I installed the cert according to the instructions provided me by GoDaddy I did associate IIS, SMTP and a couple of other services as well. Did I execute  the wrong command or miss something?

If you purchased a GoDaddy SSL Certificate you should not have to change the internal URL's.

Please advise the name of the site from the error that you are seeing or post a screen-shot of the error.

Ok. Waiting for a user to send me a screenshot of the error. So far no errors. I did a restart of the Transport service as well as an IISRESET and so far no complaints.

Also have a look at
Get-clientaccessServer | fl Identity, autodiscoverInternalUri
Change that to a name on your cert that resolves internally to the internal IP address of your CAS server (or amend internal DNS so the cert name resolves to the CAS internal IP address)
