Hello!
I have three Exchange 2013 servers with CAS role (CAS1, CAS2, CAS3)

I need to temporarily disallow client Outlook to connect to CAS3 (so that users Outlook only connects to CAS1 and CAS2), but at the same time CAS3 must remain on the network.

How can this be done?

    Disable in the load balancer pool or remove from any DNS Round Robin.

    If you dont have that, they you would need to set the autodiscover URI to another server temporarily

    Set-ClientAccessServer -Identity "CAS3" -AutoDiscoverServiceInternalUri "https://CAS1.contoso.com/autodiscover/autodiscover.xml" 
    

    Then restart the AutoDiscover App pool or iisreset.
