Question 1

What is SharePoint Storage Monster?

Accepted Answer

SharePoint Storage Monster is a SaaS tool built by CNEXT that automatically scans Microsoft 365 tenants for storage waste. It identifies version graveyards, duplicates, ROT files (redundant, obsolete, trivial), orphaned OneDrive accounts and Teams library clutter — and delivers a prioritised cleanup list.

Question 2

How much storage can I save with SharePoint Storage Monster?

Accepted Answer

Swiss SMBs save an average of 40–60 % of their M365 storage with SharePoint Storage Monster. For a typical organisation with 300 users and 2.4 TB of total storage, that's often 1–1.5 TB — translating directly into lower Microsoft 365 storage overage costs or reduced storage plan tiers.

Question 3

What exactly does SharePoint Storage Monster detect?

Accepted Answer

SharePoint Storage Monster detects six categories of storage waste: (1) Version clutter — SharePoint stores up to 500 versions per file by default. (2) Duplicates — identical files across multiple sites or teams. (3) ROT files — redundant, obsolete, trivial; not opened in years. (4) Recycle bin ballast — deleted files count against quota. (5) Teams library clutter — meeting uploads and channel attachments. (6) Orphaned OneDrives — ex-employees without active use.

Question 4

How does SharePoint Storage Monster connect to Microsoft 365?

Accepted Answer

The connection uses OAuth 2.0 with Microsoft Entra ID. A read-only permission set is configured — no admin passwords are stored. Setup takes under 5 minutes. No local installation is required.

Question 5

Does SharePoint Storage Monster automatically delete files?

Accepted Answer

No. SharePoint Storage Monster has read-only access to your tenant. Cleanups are proposed as a prioritised list. You decide what gets deleted — individually or as a batch. Every action is logged in the audit trail. Deleted files go to the recycle bin first and can be restored if needed.

Question 6

How long does a scan take?

Accepted Answer

A full scan of an M365 tenant with 1,000 SharePoint sites takes under 4 hours. Smaller environments (100–300 sites) are typically done in 30–60 minutes. The first scan analyses all sites, libraries, OneDrive accounts and Teams channels.

Question 7

Is SharePoint Storage Monster FADP compliant?

Accepted Answer

Yes. All data stays in Swiss data centres — SharePoint Storage Monster is FADP-compliant (Swiss Federal Act on Data Protection / nDSG). No file contents are read — only metadata (file name, size, date, version count, location). No data is shared with third-party services outside Switzerland.

Question 8

Does SharePoint Storage Monster have an API?

Accepted Answer

Yes. SharePoint Storage Monster offers an agent-to-agent API (REST) that enables integration into Microsoft Copilot Studio agents. Your AI agent can trigger storage analyses, retrieve cleanup proposals and surface them directly in Teams or SharePoint pages — for fully automated M365 storage governance.

Question 9

Who is SharePoint Storage Monster for?

Accepted Answer

SharePoint Storage Monster suits any organisation using Microsoft 365 — from SMBs with 50 users to enterprises with 10,000+. Particularly relevant for organisations already paying Microsoft 365 storage overages or looking to reduce storage costs as part of M365 optimisation. CNEXT supports Swiss clients with initial setup and results interpretation.

Question 10

How does SharePoint Storage Monster differ from native Microsoft tools?

Accepted Answer

Microsoft's SharePoint Admin Centre provides basic storage reports. SharePoint Storage Monster goes much further: it identifies duplicates (not available natively in Microsoft), analyses version histories for savings potential, prioritises ROT files and delivers a directly actionable cleanup list. The agent API also enables integration into Copilot Studio workflows.
