How Teams and SharePoint Work Together
Microsoft Teams is more than just chat — it’s also a hub for your files, meetings, and collaboration. Behind the scenes, Teams is tightly connected to SharePoint.
If you've ever uploaded a file to a Teams channel and wondered where it went — this explains it.
Every Team Has a SharePoint Site
When a new Microsoft Team is created, Microsoft 365 automatically creates:
A SharePoint site (for files)
A Microsoft 365 Group (for permissions and calendar)
A OneNote notebook (optional)
All of this happens in the background — no extra setup required.
Where Files Are Stored
Files in a Teams channel:
Are stored in the connected SharePoint site
Each channel has its own folder inside the SharePoint document library
These files are shared with everyone who’s a member of the Team
You can access them:
From the Files tab in Teams
Directly in SharePoint
Or through OneDrive, if a shortcut is added
Files in a Teams chat (1:1 or group):
Are stored in the sender’s OneDrive
Shared automatically with the chat participants
These are not part of a SharePoint site
Why It Matters
Teams is the interface, SharePoint is the storage
If you leave a file in a Teams channel, it’s in SharePoint — with proper permissions and structure
If you send a file in a private chat, it’s in your OneDrive and shared ad hoc
This means:
Use Channels for shared work that should stay accessible to the team
Use Chat for quick or temporary file shares
Viewing a File’s SharePoint Location
To view where a file lives in SharePoint:
Go to the Files tab in any channel
Click Open in SharePoint
This opens the SharePoint folder behind that channel
What About Permissions?
Everyone in the Team has access to the connected SharePoint site and its files
If you need to restrict access further, move the file to a private SharePoint site or OneDrive and share it manually
Summary
Action | Stored In |
---|---|
Upload a file in a channel | SharePoint |
Upload a file in a chat | OneDrive (sender) |
Open in Teams → Files tab | SharePoint folder |
Share a file in 1:1 message | OneDrive, shared |
Understanding this connection helps you manage files more effectively and avoid permissions issues down the road.
