Setting Backend Exchange 2013 / 2016 Virtual Directory

This is a tale of when a “quick” review of CAS namespaces quickly went off at a tangent.  When working with the messaging administrator, let’s call him “Mike” to protect the innocent, he showed me the below for his Exchange 2013 server.  He was quite happy with the config, but that bubble was about to…
