Hi everyone,


I have a question, regarding the unified labeling. We used to use AIP deployed scanner and it was configured in a way that:


Internal documents/emails cannot be shared with external domains. When you try to send it,


We've started using unified labeling, and we currently have an issue with the fact that label matching is not working. I.e. 


If I open and create a "Public" email, I can add attachment with "Internal" label and send it just fine to an external domain. 


Anyone know how this is enabled via the unified labeling Purview solution?

You should use an Exchange online DLP with "content contains" and select the sensitivity label.
