I'm trying to figure out how to configure a mail rule in Exchange 365 in order to identify mail that has a different Reply To address than the Sender address. I'd like the user to get a warning like a mail tip just so they are aware that it is a different address in case it turns out to be fraudulent. We've had some phishing attempts lately, and I'd like to put that in place as an extra precaution.<br />

Thanks!
