In this case, if I’m understanding it right, the traffic never got IN to the Office365 environment, or if so, it might not have been associated with the actual domain in question, but … the number of times I’ve used Message Trace can be counted on the fingers of one hand; I much prefer working with NDRs and the full headers in such cases. ☹

I'm not sure if you can comment on one part of my original question. In this situation the message obviously didn't make it from hotmail to Office 365 because of the expired domain / no MX records--but in the past I've tried troubleshooting rejected messages and they frequently won't show up in message tracing. Is there a point in the spam filtering where a message can get rejected, but it doesn't show up in tracing? -A
