Hello all
I am running Exchange 2013 CU8. I have two AD sites, and two DAG's. 5 mailbox servers in each DAG, and 4 CAS servers in each AD site. Environment looks similar below. The picture shows 4 CAS, however i have 8. What i want to know is it best practice to route smtp email through the CAS servers ? what is the advantage to using FrontendProxyEnabled ?
