OneDrive and SharePoint are both included in Microsoft 365, they both store files in the cloud, and they both sync to your desktop. So why do they both exist — and which one should you be using? This is one of the most common sources of confusion for Microsoft 365 users, and the answer is simpler than Microsoft’s documentation makes it appear.
The Simple Explanation
- OneDrive = your personal storage. Files that belong to you.
- SharePoint = shared team storage. Files that belong to the business or a team.
If you’re working on a document that only you need access to — drafts, personal notes, your own working files — it goes in OneDrive. If it’s a document that your team, department, or entire company needs access to — price lists, templates, shared procedures, project files — it goes in SharePoint.
OneDrive in Detail
Every Microsoft 365 user gets their own OneDrive — a personal cloud drive that works exactly like a folder on your computer, but synced to Microsoft’s servers. You get 1TB of storage per user (with most business plans). Files in your OneDrive are private by default. You can share individual files or folders with specific people, but the default state is that only you can see them.
OneDrive syncs to your desktop via the OneDrive app, making files available offline. On Windows 11, it integrates directly into File Explorer so it looks and behaves like a local folder.
When to use OneDrive
- Draft documents you’re working on before sharing
- Personal notes and reference files
- Photos and files from your phone
- Files you want to share with one or two specific people temporarily
SharePoint in Detail
SharePoint is a team collaboration platform that Microsoft 365 uses as the underlying file storage for Teams. When you create a Team in Microsoft Teams, a SharePoint site is automatically created behind it — the files tab in Teams is actually a SharePoint document library in disguise.
SharePoint is designed around groups of people sharing access to a set of files. Rather than sharing individual files, you give someone access to a library or site and they can see everything in it.
When to use SharePoint
- Company-wide documents — HR policies, procedures, brand assets, templates
- Departmental files — sales team documents, project files, client records
- Anything that needs to survive a staff member leaving the business
- Files that multiple people edit simultaneously
- The underlying storage for your Microsoft Teams channels
Why Does This Confusion Exist?
A few reasons. First, both look similar in the browser and both appear in File Explorer if you sync them to your desktop. Second, you can share files from both places, which blurs the boundary. Third, the OneDrive app on your desktop will also sync your company SharePoint libraries, so they appear in File Explorer under your OneDrive folder — which makes it look like SharePoint files are in OneDrive.
The Risk of Getting It Wrong
The most common mistake is storing important company files in a personal OneDrive. If that person leaves the company and their account is deleted, those files can be lost. Company files — anything that other people need, or that the business needs to retain — should be in SharePoint, where admin controls govern access and retention independently of individual user accounts.
Practical Setup Advice
If you’re setting up Microsoft 365 for a small team, a simple structure works well:
- Create one SharePoint site per team or department (this happens automatically when you create a Team in Microsoft Teams)
- Inside each SharePoint site, create a folder structure that mirrors how the team works
- Brief staff: personal work-in-progress in OneDrive, shared/final documents in SharePoint/Teams
You don’t need to be perfect about it on day one. Most businesses start simple and refine their structure over time as they understand how they use it.
What About OneDrive for Business vs Personal OneDrive?
There are two versions of OneDrive. OneDrive personal is the consumer version (tied to a personal Microsoft account). OneDrive for Business is the version included in Microsoft 365 subscriptions and tied to your work account. They look similar but are separate. Your work files should always be in your OneDrive for Business account, not your personal OneDrive.
