Microsoft 365 Archive: File-level archiving General Availability

🚨 The Signal: Microsoft 365 Archive now supports file-level archiving in SharePoint, moving individual files to cold storage. This optimizes costs while retaining existing security, compliance, and eDiscovery capabilities, but introduces a potential delay for file reactivation.

The Impact

All Microsoft 365 commercial and education tenants are affected, with a low security risk due to consistent application of existing security controls.

  • Users with edit permissions can archive files, potentially impacting immediate data access if not managed.
  • Users with read permissions can reactivate files, but delays up to 24 hours could affect business continuity.
  • Security teams must ensure existing data governance policies are understood in the context of archive delays.
  • Compliance teams should verify that the archiving process aligns with data retention and eDiscovery requirements.

The Action

  1. Review existing data retention and eDiscovery policies to ensure they account for file-level archiving and reactivation delays.
  2. Communicate to end-users the process for archiving and reactivating files, including potential delays.
  3. Monitor audit logs for archiving and reactivation activities to ensure compliance and detect anomalies.
  4. Verify that sensitivity labels and permissions are correctly inherited and applied to archived files.
