Exchange 2019 - Windows Server Core
The current version of Exchange can, and in most cases should, be installed on Windows Server Core. Windows Server Core is a version of the Windows Server operating system that does not have a Graphical User Interface (GUI). Since “windows” are well ingrained into the administrative habits of most of us Windows Server administrators, it’s reasonable to expect that most Exchange administrators are going to be a bit hesitant to go down this route.
