The easiest way to test these types will be:
- using Data Loss Prevention (DLP) policies, or
- you can try these out in the new Simulation Mode using the SharePoint Online (SPO) auto-labeling feature (which we went GA yesterday!)
We are currently reviewing release cycles to plan when these will be available to additional clients (such as Microsoft 365 Apps – formerly Office 365 Pro Plus).
An important aspect of this preview is sharing the results of your testing with our preview team.
The private preview will begin rolling out this week. You can sign up to express your interest in joining this preview program by completing the following form.
