Exchange 2016 – Cannot Create a ‘Frontend Transport Receive Connector’

KB ID 0001333 


When trying to enable an IP to ‘Relay’ though my Exchange server, I found I was unable to select ‘Frontend TransportConnector’.

Exchange 2016 Cannot Create Frontend Receive Connector


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.

New-ReceiveConnector -Name “Allow-Relay-Connector” -Bindings ("") -RemoteIPRanges ("”) -MaxMessageSize 20MB –TransportRole FrontendTransport -Usage Custom –Server PNL-MAIL
