How to redirect mail away from local Exchange Server to new Hosted Exchange service

We have a Windows SBS 2011 Server. We had been running Exchange locally until we decided to move to a hosted Exchange service off-site. Now when we try to setup a Outlook mail client to the new Hosted Exchange, it keeps asking for the username and password and doesn't authenticate. If we change the local machine's NIC DNS address to an outside number instead of the server, it authenticates to the Hosted Exchange Service. Our Autodiscover is working correctly when it looks outside of our network.

Is there a way to tell the SBS to point all mail with XYZ.com address outside of the network instead of the local Exchange where it used to be pointed?

The best way is to remove Exchange from the SBS server completely.
When you have Exchange installed on the domain then Outlook will do what you are experiencing, because that is how Exchange works with the AD clients. By removing Exchange you will stop that from happening.

In the meantime, run the following command from EMS:

get-clientaccessserver | set-clientaccessserver -AutodiscoverServiceInternalURI https://host.example.com/Autodiscover/Autodiscover.xml

where host.example.com is the host name your hosted Exchange provider has told you to use for Autodiscover.

Removing Exchange from the server should be the main course of action though.
