We are providing this update because your tenant is utilizing sensitivity labels and Microsoft SharePoint Online.
Coming soon: A new capability that ties together SharePoint Online library permissions and Purview sensitivity labeling and protection. We are happy to bring this capability to Public Preview. This is an opt-in feature in Microsoft PowerShell.
This message is associated with Microsoft 365 Roadmap ID 467254.
When this will happen:
Public Preview: We will begin rolling out mid-November 2024 and expect to complete by mid-January 2025.
We will communicate the plan for General Availability in a separate post.
How this will affect your organization:
After this rollout, SharePoint Online document library owners will be able to apply a sensitivity label at the library level, automatically applying that label to all unprotected and unlabeled files (Microsoft Word, Microsoft Excel, Microsoft PowerPoint, and PDFs) in the target library. This simplifies labeling in bulk across document libraries in an organization. This capability also helps protect files as they egress from the original document library, such as for collaboration purposes or attempted exfiltration. Files downloaded from these libraries are protected at download. Users accessing these files outside of SharePoint Online have their rights evaluated in real time against the document library. Changes to user permissions on the document library are reflected on downloaded files, including full revocation for users removed from the document library. This provides a more streamlined way to revoke access to documents for individual users (instead of revoking access to each document).
