OneDrive for Business is the file library attached to one person’s Entra ID account. SharePoint is the site and document libraries a team or department owns. Both store files on the same Microsoft 365 service. The difference is ownership: “mine until I share it” versus “the team’s, whether I stay or leave.”
The Microsoft 365 plan article names both products. This guide is how to choose where a file should live.
Side-by-side
| Question | OneDrive | SharePoint |
|---|---|---|
| Default owner | One user | A site (owners and members) |
| Typical use | Drafts, personal working files, files not yet ready for the team | Policies, project files, department records |
| What Teams “Files” often is | Files in a private chat (OneDrive of the sender) | Files in a channel (a SharePoint library) |
| When the person leaves | The library can be accessed by an admin for a time, then should be transferred | Files stay with the site |
| Sharing | The person shares a file or folder | Site permissions plus optional file links; see libraries and permissions |
“OneDrive” on a home PC (personal Microsoft account) is a different product. This page is OneDrive for Business inside a tenant.
A Microsoft 365 group or a Team already has a SharePoint site. Saving a department policy only in one manager’s OneDrive is how that policy disappears when the manager resigns.
How to choose
Put a file in OneDrive when it is still personal work, or when it would not make sense if the author were away. Put it in SharePoint when more than one role must find it next year.
Sync clients can show both in File Explorer. That convenience is why people mix them. A synced folder named “Company” that actually sits in one person’s OneDrive is still OneDrive.
External sharing exists in both. The risk is different: a personal sharing link from OneDrive is easy to forget; a SharePoint library can inherit a site-wide guest. Set tenant defaults first, then teach staff where to save.
Deciding where a new file belongs
- Ask who must still find this file if you leave next month
- If the answer is a team or a role, use a SharePoint library
- If the answer is only you, use OneDrive
- Move the file to SharePoint when it becomes a shared record
- Share a link from the final location, not from an old copy
Storage quotas and recycle bins
Each product has its own quota and recycle bin. Deleting a OneDrive file does not free SharePoint space. Restores follow the library you deleted from. Admins can recover a leaver’s OneDrive for a limited period; they cannot invent a department library that never existed.
A practical example
A sales folder lives in the sales manager’s OneDrive, synced to a laptop, shared with five people by link. The manager leaves. Links break or linger without an owner. The revision creates a Sales site library, moves the closed-year files there, and leaves only personal pipelines in OneDrive. Teams channel files for Sales already pointed at that site.
Key takeaways
- OneDrive is personal. SharePoint is the team’s.
- Channel files in Teams are SharePoint. Chat files are OneDrive.
- If the team needs the file next year, it does not belong only in one person’s drive.
- Share from the final library, not from a leftover copy.
FAQ
Can we turn OneDrive off and use only SharePoint?
You can discourage OneDrive for records. Staff will still get a OneDrive with their licence. Teach the split; do not pretend the library is gone.
Is SharePoint only for intranet pages?
Pages are one part. Document libraries are how most SMEs meet SharePoint, including through Teams.
What about a file that must stay private to one director?
OneDrive, or a SharePoint library with unique permissions and two owners. One owner is a single point of failure.
