OneDrive is for an individual's working files, SharePoint is for shared team and company content, and Teams is a collaboration workspace that stores its files in SharePoint. Knowing the difference prevents lost files and oversharing.
Key takeaways
What to know before you act
- OneDrive is for individual work; SharePoint is for shared content; Teams files are stored in SharePoint.
- Business-critical files should live in team-owned locations, not in one person's OneDrive.
- A simple storage guide and named site owners prevent sprawl and oversharing.
Why it matters
What business leaders should understand
When important files live in personal OneDrive folders, they can become hard to find or at risk when someone leaves. A simple storage standard improves collaboration, permissions, and retention.
The right response should reflect your environment, data, vendors, risk, and operational priorities. Use this guide as a practical starting point, then validate important decisions with the people responsible for your technology, cybersecurity, legal obligations, and insurance coverage.

How the three fit together
OneDrive for Business is each user's personal work storage: drafts, working documents, and files they own. SharePoint provides sites and document libraries for departments, projects, and company-wide resources. When you create a team in Microsoft Teams, Microsoft 365 creates a SharePoint site behind it; files shared in a channel are stored in that site's library.
- My draft or personal working file → OneDrive.
- Files my team works on together → the team's channel (SharePoint behind Teams).
- Company policies, templates, and reference documents → a SharePoint communication or department site.
- Files shared in a one-to-one or group chat → the sender's OneDrive.
Governance basics
Without guidance, users create teams for every conversation and share files from personal storage. Publish a short storage guide, decide who may create new teams, and assign at least two owners to each site or team. Review guest access and sharing links regularly, and archive inactive teams.
When an employee leaves, their OneDrive is subject to retention and deletion rules, so move shared business files to SharePoint before offboarding.
