File-Level Archival: The Next Frontier of Microsoft 365 Storage Optimization

You’ve archived every inactive site. Why are storage costs still rising?

Because the real problem isn’t sites. It’s files.

Terabytes of stale, untouched files are sitting inside active SharePoint and OneDrive sites, and they’re never going to be archived. Until now, your only options were risky migrations or manual cleanup.

Costs quietly pile up over time, and most organizations just pay for it.

Microsoft 365 File-Level Archiving

Microsoft just introduced file-level archival, a better way to reduce Microsoft 365 storage costs by moving individual files into cold storage without losing visibility, search, or compliance.

The catch? Native tooling is manual and end-user driven.

Archiving at enterprise scale requires a different approach.

Join Orchestry & Microsoft

Join us for a live session with Trent Green, a Microsoft Program Manager behind file-level archival, alongside the Orchestry team. We’ll walk you through what file-level archival actually does, how it works, and how to turn it into a scalable, automated strategy across your tenant.

What you'll learn

✅ The difference between site-level vs. file-level archival
✅ How file-level archival works: cold storage, reactivation, admin controls, and billing
✅ Where native tooling breaks down and automated governance takes over
✅ How to define rule-based archival criteria (inactivity, file type, file size)
✅ Why archived content is excluded from M365 Copilot and why that matters for AI readiness

Move beyond site-level cleanup. Reclaim terabytes (even petabytes) of storage, reduce overage costs, and keep the content that matters.
