Summary:
Microsoft 365 Archive now supports file-level archiving in public preview, allowing SharePoint files or folders to be moved to low-cost storage while remaining visible with metadata and compliance intact. Admins enable the feature; archived files are excluded from search and Copilot, with reactivation timing varying by duration.

Details:
[Introduction]
We are introducing file-level archiving for Microsoft 365 Archive. This capability allows organizations to move individual SharePoint files or folders into low-cost archival storage while keeping them visible in their original location. This helps reduce storage costs and optimize content lifecycle management without losing metadata, permissions, or compliance coverage.
This message is associated with Microsoft 365 Roadmap ID 477371.
[When this will happen]
Public Preview: Available now.
General Availability (Worldwide): Rollout begins in late June 2026 and is expected to complete by late July 2026.
