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 https://mail.contoso.com/OAB -RequireSSL:$true
When I run the command for EWS (Default Web Site) I get "The host specified for the "ExternalUrl" parameter can't be resolved"
Set-WebServicesVirtualDirectory -Identity "CAS01\EWS (Default Web Site)" -ExternalUrl https://mail.contoso.com/EWS/Exchange.asmx -BasicAuthentication:$True
