🔹 Feature: File-Level Archiving in Microsoft 365 Archive
🔹 What It Does: Microsoft 365 Archive moves inactive SharePoint content into a low-cost, compliant cold-storage tier — content remains in SharePoint with full Purview security and retention, and can be reactivated on demand. The March 2026 adds file-level archiving — no longer just full-site archiving.
What Is It Giving You:
✅ Granular, File-Level Control: Archive individual files in active sites — like old project docs or completed-event material — without archiving the entire site.
✅ Better Copilot & Search Relevancy: Archived files drop from Copilot’s active index, keeping current content front and center.
✅ Files Stay Inline: Archived files remain in-place with a visual indicator — users see context without losing awareness.
✅ 7-Day Instant Grace Period: Reactivate instantly within 7 days.
✅ Predictable Reactivation After That: Up to 24 hours for reactivation beyond the grace window — clear SLA for cold-to-hot transition.
✅ Copy & Move Aware: Archive status follows files across copies and moves.
✅ Metadata Stays Fully Usable: Custom columns and tags remain editable.
✅ Always Reactivatable, Anywhere: Archive capability travels with the file.
✅ Permission-Gated Reactivation: Reactivation requires existing read permissions.
💰 Save up to 75% on SharePoint storage; charges only apply beyond your tenant quota. No reactivation fees.
