What StorageScout finds

Native reports show usage. StorageScout turns it into money and a plan — the reclaimable GB, priced against your add-on rate, prioritized and client-ready.

$

Tenant storage position

Used vs your pooled allowance vs add-on purchased — exactly how far over you are, in GB and dollars.

Orphaned OneDrives

OneDrives of deleted and disabled users, still quietly consuming pooled storage.

Version-history bloat

Excess file-version history across libraries — reclaimable in place by trimming.

Recycle-bin bloat

First- and second-stage recycle bins holding GB you've already "deleted".

Stale sites

Sites with no activity in N months — archive candidates you can offload.

Near-quota sites

Sites approaching their limit — fix them before uploads start failing.

How it works

No SaaS sign-up, no tenant connection to a third party. You run it; the report stays with you.

Connect read-only

Run the PowerShell script. It signs in to Microsoft Graph with read-only scopes you consent to. StorageScout has no servers — nothing is sent anywhere.

Scan & quantify

It reads your SharePoint and OneDrive usage reports, finds reclaimable storage, applies your add-on price, and computes recoverable spend.

Act on the report

Open the HTML report + CSVs, work the remediation checklist, reclaim storage, and drop your add-on at renewal. Re-run monthly.

Simple, one-time pricing

Buy it once, own it. Reclaiming a single wasted terabyte (~$200/mo) pays for the Pro tier in its first month.

Questions

Does my tenant data leave my environment?

No. StorageScout is a script that runs inside your tenant against Microsoft Graph. There is no StorageScout server and nothing is uploaded. The report is written to your own machine.

What permissions does it need?

Read-only Microsoft Graph scopes, chiefly Reports.Read.All (for SharePoint/OneDrive usage) plus Sites.Read.All, User.Read.All, Organization.Read.All and Directory.Read.All. You consent at run time. It never writes changes.

How is "recoverable" calculated?

Reclaimable storage (orphaned OneDrives + version-history + recycle-bin bloat) is capped at the amount you're currently over your free pooled allowance — because that's the storage you're actually paying add-on for — then multiplied by your add-on price. Conservative by design.

Will it change anything in my tenant?

Never. It is strictly read-only and produces a report plus a remediation checklist. You decide what to action — and should always respect retention/legal hold before reclaiming.

Do I need to be a SharePoint admin?

To pull tenant-wide usage reports you need reporting rights (Reports.Read.All — a Global Reader or Reports Reader can consent). Without them StorageScout still runs, but with a limited view, and tells you so.

Can I use it across client tenants?

Yes — the Pro tier is licensed for unlimited client tenants and white-labels the report with your brand, built for consultants and MSPs.
