  • Hi 

    Lets try to reproduce the scenario with the below for better troubleshoot 

    1) Enable protocol logging on your connectors

    2) Enable delivery receipt from the affected external domain and try dropping an email to your user and lets collect the NDR message which will give us better information.

    3) Run Get-TransportAgent and see what are the agents that you have
