Ezt olvasom:
"Windows Server 2016 Install Windows Server 2016 and choose the Desktop Experience installation option. If a computer is running Windows Server 2016 Core mode and you want to install Exchange 2016 on it, you'll need to reinstall the operating system and choose the Desktop Experience installation option."
Ez most komoly?
Eddig a Core-t lehetett konvertálni: https://blogs.technet.microsoft.com/john_taylor/2013/01/08/converting-from-server-2012-core-install-to-full-gui/
Még jó, hogy nem is terveztem, hogy core-t telepítek az Exchange alá.
