Exchange 2016 :- Prevent a server proxying CAS traffic to another server CAS Server

In this short post, we will look at preventing a CAS server from proxying traffic.

Let’s suppose you are migrating from Exchange 2010 to 2013 or even 2016 and you do not want your Exchange 2010 Server/s to act as a proxy target.

You could run the following command to enable this:

• Set-ClientAccessServer –identity CASServer1 –IsOutOfService $true

Once that command is run, CASServer1 in this example will not receive any more proxy traffic from other CAS servers until you set the command to false.
