@JSlei Hello again, didn't you look for an option to protect at scale without anyone have to review the documents? Are you saying this isn't applicable even if using PowerShell cmdlets for it?
"Manual application of sensitivity labels is a good way to protect new messages and documents but does nothing to deal with the mass of documents and messages that already exist inside Office 365. To address the issue, Microsoft is running a preview program for auto-labeling Word, Excel, and PowerPoint files stored in SharePoint Online sites and OneDrive for Business accounts (Exchange Online will come later). The solution is intended to allow Office 365 tenants to protect existing content at scale without needing anyone to review large quantities of documents."

"It is definitely possible to solve with a script, however, with the MIP SDK. But why bother, MCAS can put a label on all documents in an SP site. Then Microsoft is rebuilding SharePoint online right now to force all files that do not have a manually set label in an SP site based on its container label."
The latter being the roadmap item I linked to above scheduled for release in December.
