I need a solution
What is the best bractice for implementing EV in such below environment.
I have two main datacenters and one disaster recovery datacenter.
One of those MS exchange server is located in main datacenter as two mailboxes databases with DAG and two CAS/HUB with network load balancing (NLB).
The other MS exchange server is located in another building as one server with all roles and a second server with mailbox role without DAG and NLB between servers.
