Exchange 2016 – Cannot Create a ‘Frontend Transport Receive Connector’
KB ID 0001333 Problem When trying to enable an IP to ‘Relay’ though my Exchange server, I found I was unable to select ‘Frontend TransportConnector’. Solution Apparently this is a a bug first seen in CU2, the only current fix is to either create the connector as a Hub Transport connector, then convert it using PowerShell, or create the connector in the Exchange Management Shell, which is what I did....
