You would need appropriate certificates for the autodiscover DNS names and ports to be open on firewall.

Actually, what I want to knowis how do Outlook clients know about Autodiscover.
After creating a Host(A) Record in DNS named "AutoDiscover" and you point it to IP address of the CAS array server for instance( Then how would this configuration alone by itself make Outlook clients discover the CAS array ?
There might be other configs involved. if So couldyou please give the details?

Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

This is a massive subject which is very complex. I'm not proffessing to understand it entirely but I believe several factors play a part.

I think Outlook queries the server and if the server appears to support autodiscover then it will use the details that the server supplies.

In the past, I've tried to disable the auto discover system one a client's system but never quite managed to remove all of it. The result was a certificate warning every time they open outlook.

Unless you're looking for a very steep learning curve, I'd suggest you try and go with a recommended system setup. Looking back, fighting it wasted me more time than it would have take. To learn to use it properly!

I  am also not sure if I need to configure on CAS server as (Internet facing) and the othe CAS server Not internet facing?

I'm not sure to be honest. I've only been involved with single servers. However, I would think the external server definitely needs to be configured. Not sure about the internal server - you could try it without and see what happens?
