We have been using Exchange 2k7 on Server 2k8 with no Outlook problems. Now as we are installing Windows 7, outlook claims it cannot connect with the server - "the connection to Microsoft Exchange is unavailable". It croaks trying to do its auto setup and then opens up a box asking me to correct the fields describing the exch server and the SMTP address of the client. Both are correct. I have seen numerous posts related to this but did not find a solution. Even though we never fully setup autodiscovery website (Xp/Vista worked without it), I setup the DNS A rec for autodiscovery and made sure the CAS provider info was correct. Still no change in behavior. This seems like a common problem - we have a very basic setup here. Any of you exchange experts able to come to the rescue? Much appreciated.
