Stop paying to store Microsoft 365
content nobody needs.

SharePoint and OneDrive storage grow automatically as your organization collaborates and creates content, and Microsoft charges for anything that exceeds your quota. The ENow 365 Governance Accelerator finds the redundant, obsolete, and orphaned content quietly inflating your Microsoft 365 storage, and shows you exactly what you can reclaim.

Why SharePoint storage keeps growing

Your Microsoft 365 storage bill keeps increasing without your team even realizing.

Microsoft 365 includes a pooled storage allowance for every organization that grows with licensing, but many environments outgrow it quickly. Here is where the cost actually comes from:

01

Storage that expands automatically with collaboration

Every new site, team, and OneDrive adds storage. Copilot and AI-driven content creation accelerate it. Growth is silent until you cross your quota.

02

Overage you pay for at a premium

Once you pass your pooled allowance, you buy more Microsoft storage to keep working, and it is not cheap. Most teams buy more before checking whether they can reclaim what they already have.

03

Redundant, obsolete, and trivial (ROT) content

Old files, duplicates, and abandoned sites nobody owns accumulate for years. Most organizations cannot tell you today how much of their storage is content no one will ever open again.

04

Version history and recycle-bin bloat

Retained versions and unemptied recycle bins consume storage invisibly, often accounting for a surprising share of a site’s footprint.

05

Inactive and orphaned sites

Sites created during a busy quarter outlive their purpose but keep consuming quota, with no owner accountable for cleaning them up.

SharePoint storage management

See exactly what you’re paying to store, and what you can safely reclaim.

Think of it as SharePoint storage optimization built on visibility: the Accelerator reports on what every site, file, and version is actually costing you, so you reclaim waste instead of buying more Microsoft 365 storage.

 

Find reclaimable storage

Surface redundant, obsolete, and orphaned content across SharePoint and OneDrive, with the storage each item consumes.

 

Quantify the savings

See reclaimable storage in GB, and the estimated cost attached to it, so you can build the business case for cleanup instead of a purchase.

 

SharePoint Online storage reporting

Rank your biggest consumers: largest sites, oversized files, version-history and recycle-bin bloat, ordered by footprint.

 

Flag inactive and orphaned sites

Content with no recent activity or accountable owner, safe to archive or remove.

 

Right-size before you buy

Know what to clean up before purchasing additional Microsoft storage.

 

Monitor continuously

Track storage growth and cost trajectory over time, so this is ongoing control, not a one-time cleanup.

See how you could reclaim in your own environment.

We’ll walk through identifying your storage footprint, the biggest consumers, and what’s safe to clean up.

Cost and risk

The content inflating your bill is the same content exposing your data.

The redundant, orphaned, and forgotten content driving your storage costs is exactly the content that creates governance and Copilot exposure. A stale site with no owner is both wasted storage and an unguarded door. Cleaning it up cuts cost and risk in one motion.

This is why storage cost optimization is part of the ENow 365 Governance Accelerator, not a separate tool. The same continuous visibility that scores your governance posture finds the storage you’re paying to keep.

What organizations achieve

Turn a rising storage bill into a defensible, one-time win, and keep it that way.

Lower Microsoft 365 storage costs by reclaiming ROT and stale content
Fewer surprise overage charges as growth is monitored, not discovered on the invoice
A documented, defensible cleanup you can show finance, IT leadership, and audit
A cleaner environment that is safer for Microsoft Copilot
Continuous control instead of a one-time storage cleanup that re-bloats in six months
FAQ

Microsoft 365 storage questions, answered

Still have questions? Talk to our team.

How do I reduce SharePoint and Microsoft 365 storage costs?

+

Start by finding what you are already paying to store but no longer need: redundant, obsolete, and trivial (ROT) content, excess version history, full recycle bins, and inactive or orphaned sites. Cleaning these up reclaims quota before you buy additional Microsoft storage. The ENow 365 Governance Accelerator surfaces this content across SharePoint and OneDrive and shows how much storage each item consumes.

Why does my SharePoint storage keep growing?

+

SharePoint and OneDrive storage grows automatically as people collaborate. Every new site, team, and OneDrive adds storage, retained file versions accumulate, and sites outlive their purpose with no owner to clean them up. Copilot and AI-driven content creation accelerate that growth.

Does Microsoft charge for extra SharePoint storage?

+

Microsoft 365 includes a pooled storage allowance that grows with licensing. Once your organization exceeds it, you pay for additional storage to keep working. Reclaiming unused content first can reduce or delay that purchase.

What is ROT data in Microsoft 365?

+

ROT stands for redundant, obsolete, and trivial content: duplicate files, outdated documents, and content no one will open again. It inflates storage costs and, because it often sits in unmanaged locations, it also creates governance and Copilot exposure risk.

How do I optimize SharePoint Online storage?

+

Optimizing SharePoint Online storage takes continuous visibility, not a one-time cleanup. Rank your largest sites and files, review version history and recycle-bin usage, flag inactive and ownerless sites, and track storage growth over time so the environment does not re-bloat.
