  • Just always specify "-TransportRole FrontEndTransport" and you'll probably never go wrong.

  • Hi,

    Please refer the below article so that you will have a clear understanding of what both of these connectors are. Based on that, create the type of receive connector you would like for your scenario.

  • Hi,

    I would read this document to understand receive connectors firstly:

    https://technet.microsoft.com/en-us/library/aa996395(v=exchg.150).aspx

    When we create receive connectors in EAC, we can choose the role of receive connector, or use Exchange Powershell parameter as Ed suggested.

    Sure Ed, The server that I need to manually create this receive connector will be mixed role MAILBOX & CAS server. Hopefully that is the correct ones to select.

  • Thanks Lyn, Can I change the connector later on if somehow I create it as wrong type or conflicting with the default mailbox or CAS server role ?

  • Dileepa, I assume when I add the CAS role manually tomorrow, the Default CAS receive connectors will be automatically created along with the existing default mailbox server receive connectors.

  • You will generally be creating connectors using TCP port 25, and since you will have at least one connector using that port in FrontEnd transport, you'll get a message telling you that.  So you'll be reminded to supply the -TransportRole FrontEndTransport parameter or select the correct radio button.
