Exchange 2010 CAS setup getting this error "The host specified for the "ExternalUrl" parameter can't be resolved"

I am installing my first Exchange 2010 in my environment.
This will be a 2003 to 2010 transition.  
I am using a wildcard SSL from Godaddy.
I installed the CAS role on server and started the Autodiscovery setup. I was able to set the external address for OAB (Default Web Site).

Set-OABVirtualDirectory -Identity "CAS01\OAB (Default Web Site)" -ExternalUrl -RequireSSL:$true

Open in new window

When I run the command for EWS (Default Web Site) I get  "The host specified for the "ExternalUrl" parameter can't be resolved"

Set-WebServicesVirtualDirectory -Identity "CAS01\EWS (Default Web Site)" -ExternalUrl -BasicAuthentication:$True

Open in new window

Tell me you are not using and instead are using your mail domain name for the externalurl property. I'm pretty sure you aren't using contoso but if I didn't say it and you were then we would look pretty silly.

I am not. :)

I ran the
[PS] C:\Windows\system32>Get-WebServicesVirtualDirectory | Set-WebServicesVirtualDirectory -ExternalUrl -BasicAuthentication:$True

Open in new window

Get-WebServicesVirtualDirectory -Identity "xxxEXCAS01\EWS (Default Web Site)"

Open in new window

Now I do not get the error, but I do not see the column for the ExternalURL like I did with

Even though I do not see the external url column does this mean that it is configured correctly?
Try this in EMS and see if you get a value for externalurl:

Get-WebServicesVirtualDirectory | fl server,externalurl

Thanks guys.  
I added Host A Record  to my DNS zone for Mail prior to running the Set-WebServicesVirtualDirectory.
That might have done the trick.  
I feel that you both deserve the points.
