Exchange 2013, Domain Secure. (Not MTLS)

Hey Guys,

I am trying to get this to work: https://technet.microsoft.com/en-us/library/jj673037(v=exchg.150).aspx basically the document says to create partner connectors and then you will be able send TLS secured email between 2 environments. But for whatever reason I cannot get it to work.

I always get the same error message: 550 571 Client Not Authenticated, if I select "Anonymous Users" on the receive connector, then it works but the email does not come through as "Authenticated" but rather as "Anonymous".

Any ideas?

Thanks,

Robert
