We have postmaster DLP rule in our M365 environment. This rule will send us the suspicious email in an attached .eml format. We can see the actual header information when we open that email attachment. However, PAB button is grayed out for all the attached .eml emails. It would be very beneficial if there is a way to report the .eml attachment email via PAB so we can Quarantine it before it delivers to users inbox.
