Hi Experts
I am using new to exchange 2010 hybrid environment.

We create users in exchange onprem and migrate to cloud, what funcationility do CAS play in hybrid environment. What i understand is CAS communication includes message transport and messaging features between the on-premises and Exchange Online

Do exchange 2010 CAS servers listen to port 25?

Can the ports 80 & 443 disabled on cas servers?
