The Hidden Costs of SharePoint Sprawl
"We'll just put it in SharePoint."
It’s the default decision for most organizations migrating to Microsoft 365. But without a strict governance policy, SharePoint and Microsoft Teams quickly descend into chaos: orphaned folders, duplicate files, broken permissions, and runaway storage fees.
Here is the true cost of SharePoint sprawl — and how to clean it up.
1. The Productivity Tax
When files are scattered across random Teams channels, personal OneDrive folders, and deeply nested SharePoint folders, employees spend a significant amount of time just looking for information. A study by IDC found that the average knowledge worker spends 2.5 hours per day searching for files.
If your team has to ask "which version of the contract is active?" or search multiple folders for a template, you are losing billable hours.
2. Microsoft 365 Storage Overages
Microsoft 365 tenants are allocated a base amount of SharePoint storage (1 TB plus 10 GB per licensed user). Once you exceed this limit, Microsoft charges premium fees for extra storage.
If you have employees syncing large media assets, storing personal files, or keeping 50 duplicates of the same draft file, you will hit this ceiling quickly. Cleaning up duplicate versions can reduce storage footprint by 30-50%.
3. The Security & Permissions Nightmare
SharePoint sprawl leads to permission sprawl.
- Employees create folders and select "Share with Everyone".
- Former contractors retain access to project directories.
- Sensitive employee records end up in public Teams files.
Without regular permission audits and structured site collections, data leaks are an inevitability.
How to Regulate SharePoint
- Define Site Archiving Policies: Archive or delete project directories 90 days after project completion.
- Use Hub Sites: Organize separate department sites under a clean hub hierarchy instead of using one massive document library.
- Disable Guest Sharing by Default: Require approval for external link sharing and set external links to expire automatically.
