OneDrive vs SharePoint vs Teams
The single most useful Microsoft 365 decision you’ll make this year: where to save your files. OneDrive is for you. SharePoint is for your team. Teams is the conversation layer over both.
What it is
Three apps. Three roles. One confused user base. The ‘OneDrive vs SharePoint vs Teams’ question is the most common source of confusion in Microsoft 365 — and the most consequential. Get this decision right consistently and your team scales. Get it wrong and you spend years cleaning up.
OneDrive is your personal cloud storage. Files only you (and people you explicitly share with) can see. Drafts, personal work, work-in-progress.
SharePoint is your team’s cloud storage. Files belonging to a team, department, project, or the whole organisation. Structured, permissioned, retained, audited.
Teams is not storage. Teams is the conversation layer that surfaces SharePoint content alongside chat, calls, and meetings. Files shared in a Teams channel are stored in that team’s SharePoint site. Files shared in a Teams chat are stored in the sender’s OneDrive.
Why it matters
The ‘where do I save this?’ decision compounds over years. The right defaults save thousands of hours; the wrong ones lock institutional knowledge in OneDrives that get wiped when employees leave.
- Copilot reads SharePoint when answering team questions. Files saved to the wrong place don’t surface in Copilot.
- Audit trails, retention policies, and access reviews work on SharePoint, not on personal OneDrives.
- The right decision is almost never ‘whichever is fastest right now.’ It’s ‘where will this be findable in 6 months?’
The single rule
If only you will ever need this file — OneDrive. The moment a second person might need access, even just to read — SharePoint. Doesn’t matter how informal, doesn’t matter how temporary. The cost of guessing wrong is high; the cost of moving the file later is low.
When to use this
- When you’re about to save a new file and you’re not sure where it should go.
- When you’re setting up a new team or project and deciding where work will live.
- When you’re cleaning up an old environment and rationalising what should go where.
- When you’re preparing for Copilot rollout — content location determines what AI can read.
How to do it
- Ask one question: will anyone besides you ever need this file? If yes — SharePoint. If no — OneDrive.
- If the answer is SharePoint, ask: which team or project does it belong to? That’s the site. Open that site’s document library; save the file there.
- If you’re working in Teams: files shared in a channel go to that team’s SharePoint site (the right place). Files shared in a chat go to your OneDrive (treat as personal/temporary).
- When in doubt, default to SharePoint. The cost of moving a file from SharePoint to OneDrive later is trivial. The cost of recovering OneDrive files when an employee leaves is high.
- Don’t duplicate files across OneDrive and SharePoint. Pick one location. Keep the source of truth there.
Best practices
- Default to SharePoint when uncertain. The cost of moving content later is low; the cost of losing institutional knowledge is high.
- Teach the OneDrive vs SharePoint rule to every new starter on Day 1. It’s the highest-leverage Microsoft 365 conversation you’ll have with them.
- Treat Teams chat files as temporary. They go to OneDrive and disappear with people.
- Audit OneDrives quarterly. Look for files that should have moved to SharePoint by now.
Common mistakes
- Saving team content to OneDrive ‘just in case I lose access.’ That’s exactly how institutional knowledge disappears.
- Sharing OneDrive files with the whole team and expecting them to find them. They won’t.
- Treating Teams as a third storage location. It isn’t — files in Teams are in SharePoint or OneDrive depending on context.
- Not having a default. Decision fatigue is real; pick a default and stick to it.

Should I save my files to OneDrive or SharePoint?
Ask one question: will anyone besides you ever need this file? If yes, save to SharePoint. If no, save to OneDrive. The cost of guessing wrong is high (institutional knowledge disappears when employees leave OneDrives behind); the cost of moving a file later is low. When uncertain, default to SharePoint.
Are files in Teams stored in SharePoint?
Yes — Teams doesn’t have its own storage. Files shared in a Teams channel are stored in that team’s SharePoint site. Files shared in a Teams chat are stored in the sender’s OneDrive. Teams is the conversation layer; SharePoint and OneDrive are where the files actually live.
What happens to my OneDrive when I leave my job?
When you leave your organisation, your work OneDrive is typically retained for 30 days (configurable by your admin), then deleted. Files in shared SharePoint sites stay with the team. This is the strongest reason to save team-relevant work in SharePoint, not OneDrive — anything in your OneDrive disappears with you.
Can I move files from OneDrive to SharePoint?
Yes — in OneDrive, select the file or folder, click Move to from the toolbar, then pick the SharePoint library destination. Version history transfers with the file. Sharing links to the original location continue to work (they redirect to the new location). Cleaning up OneDrives by moving team-relevant content to SharePoint is one of the highest-leverage cleanup activities possible.
