I'm trying to find out if there is a way to test Outlook (2010) connectivity to Exchange 2013 prior to moving to a co-existence state. OWA tests out great, all certs are in and VD's/Outlook anywhere is configured on the 2013 system (NTLM authentication). I have configured the local machines hosts file to point to the autodiscover address of my 2013 CAS server. I can communicate to the autodiscover service properly through IE receiving ErrorCode 600.
I changed the SCP of my 2013 CAS Server to https://autodiscover.domain.com/autodiscover/autodiscover.xml - doing so did not allow outlook to connect - I received a prompt for credentials as well as error: outlook is unable to connect to the proxy server. (error code 0). Entering credentials didn't work.
I've since changed the SCP to point to that of the 2007 Exchange server as users we're complaining they couldn't connect.
I've tried multiple avenues of manually setting up outlook with no success. Outlook seems to be getting some settings properly as after I cancel the authentication prompt it shows me the GUID@domain.org as the exchange server its attempting to connect to.
Further information:
Single 2007 SP3 Rollup 11 Exchange server, Server 2003 R2

Thank you.
