Receive Connector role not selectable in Exchange 2016 CU2
Another bug in Exchange 2016 CU2. The Role of a new receive connector is greyed out. You can select “Front-End-Transport”. This is a screenshot from a german Exchange 2016 CU2.
Solution
Use the Exchange Management Shell to create a new receive connector. Afterwards, you can modify it with the Exchange Control Panel (ECP).
