Is there a way to prevent a CAS server from being used for AutoDiscover? Or if there is a way to point AutoDiscover to a load balancer, that would be helpful too. Thanks.

Hi TGIF2011, You can run "Get-ClientAccessServer | Select AutoDiscoverServiceInternalUri" to see which URL is configured for internal domain joined Clients using the SCP. With "Set-ClientAccessServer -AutoDiscoverServiceInternalUri <a href="https:///Autodiscover/Autodiscover.xml">https://<load balanced url>/Autodiscover/Autodiscover.xml you can change it to point to your load balancer.

Set-ClientAccessServer -AutoDiscoverServiceInternalUri "https://MyBigHonkingLB.domain.com/autodiscover/autodiscover.xml" Timo is correct - I put the command into the code snippet box for readability. And for the OP note that it is URI nor URL for this cmdlet :) when you are typing it in. If you are asking the question because you are introducing a new Exchange server into the org which will have a self signed certificate by default and you do not want users to hit it, run the above command and change the URL to be an existing server that has a valid cert.
