We've implemented Azure Information Protection and Unified Labelling - and we have transport rules only allowing OPEN and CONFIDENTIONAL emails to be sent out of Exchange. All emails are labelled INTERNAL by default, and emails sent labelled INTERNAL are rejected by transport rule. All good
The problem is when creating meeting - meeting invite emails are labelled, and the transport rule rejects these emails.
Is there a way to abb sensitivity labels to meeting invites? We're using Office 2016
