I am new to exchange.
I currently have 200 users, I'm in plan to implement new Exchange 2013 solution.
Could you please help to recommend the solution for this new exchange solution (Hardware) for H/A: How many Physical Servers and Capacity I will need with the growth plan up to 400 users in total in the future.
I want to have CAS server clustering, also MBX DAG. I want to have 2 physical servers, so when 1 down, I can get one up to server all clients.
If you do need more info, please feel free to let me know.
