Allow Office DLP rule exception for encrypted outbound emails
DLP rules do not allow an exception of the predicate "MessageTypeMatches" with the notify sender action. Doing so results in the error:
One of the conditions you specified can't be used for rules where you want to notify the sender. Error details: The NotifySender action isn't compatible with 'MessageTypeMatches' predicate.
I would like to trigger a rule on outbound matches unless the message is encrypted in order to enforce our internal policy compliance.
YES this is a huge need!
Yes I agree. I would like to send an educational email back to the user (and not deliver the message) if DLP match EXCEPT if they encrypted the message
Yes this enhancement is crucial for the business process. Has there been any advancement in this area?
Yes, I agree. The emails the DLP rules under Security and Compliance are much better than the email bounces you receive when you setup DLP policies in Exchange. However, since you cannot setup keyword exceptions on the Security and Compliance section of Office 365, I agree this would be a great feature update.
