Understanding what the Exchange 2016 Preferred Architecture really means
Microsoft has published its preferred architecture for Exchange 2016. On the surface, it might seem that Microsoft is taking a pretty hard line in terms of the designs they would like to see customers put into production, but many subtleties exist. You should definitely take the preferred architecture into account when you sit down to consider the shape of your Exchange 2016 deployment because it contains much good advice. But at the end of the day, you know your business and operational environment much better than Microsoft ever can, so you have to make the final decision.
