SharePoint Storage Management

Understand SharePoint storage

SharePoint Online storage is consumed across document libraries, site assets, pages, recycle bins and version history. A site inventory helps identify where storage is being consumed.

What should you report?

• Site URL and title
• Current storage usage
• Allocated storage
• Over-utilization
• Site type and ownership

Use PowerShell for repeatable reporting

For larger tenants, PnP PowerShell is useful for collecting consistent storage data across sites and exporting it to CSV.

Practical governance

Review high-consumption sites, version history, recycle bins and inactive sites before increasing tenant storage.
