You are basically seeking something that would take a decent consultant quite a bit of time to work out, as there are many aspects to the design - it simply cannot be answered in a single question on a site like this.

At a high level - multiple Exchange servers in multiple DAGs, with load balancers.

However that leaves a lot of questions to be asked of the business.

The calculator is pretty close to useless at this point, because it will make a number of assumptions that are simply wrong for a deployment of this size.

To give you an idea - my largest design to date is 250,000. It took me a week to give them the very high level design, then another ten days of working with their infrastructure team on where to place the servers, bandwidth, storage etc. Only then could we look at the actual layout of the servers themselves.
The bill for the design alone was well over UK£10,000.
