SharePoint & OneDrive storage optimization

Stop paying overage on storage you don't need.

Chronom connects read-only, scans SharePoint and OneDrive for duplicates, orphaned sites, and version bloat, and pulls you back under quota - then cleans it out. Most tenants reclaim up to 30% of their storage.

versions of every file SharePoint keeps by default - quietly multiplying your footprint.

Storage overages are Microsoft's quietest upsell. Your pooled quota fills up, you cross the line, and the per-GB charge just appears on the bill - no approval, no heads-up.

The bloat behind it is invisible in the admin center: the same file saved a dozen times, hundreds of versions per document, sites whose owners left years ago, and the OneDrives of employees long gone. By the time it shows up, you're already paying for it.

Under the hood

How Chronom turns storage signals into reclaimed space

Chronom reads live signals across SharePoint and OneDrive through the Microsoft Graph API - read-only - and maps your entire content estate to show what's stored versus what's still needed.

Kill the overage bill

Get back under quota and stop paying Microsoft's per-GB overage - before it renews and compounds next year.

safe

Reclaim, don't delete what matters

Cleanup targets duplicates, old versions and dead sites - never the live files your teams depend on.

A lighter, faster tenant

Less bloat means quicker search, faster sync and cleaner migrations - the everyday wins users actually feel.

done-for-you

Cleanup done for you

Optional managed remediation means Chronom's team clears the bloat - reclaimed space, not another to-do.

Shrink your risk surface

Fewer stale files and orphaned sites mean less to secure, govern and sift through at eDiscovery time.

read-only

Zero risk to your content

Chronom connects read-only. Nothing is moved or deleted until you review and approve the plan.
