Block File Sharing in Teams
- Hi,
As referred to in the previous link you can control external sharing on SharePoint and OneDrive at a tenant level or at a site level (with permissions), or you can apply Data Loss Prevention policies on content within SharePoint/OneDrive from the Office 365 Security and Compliance Centre
Here are the links

Best, Chris
No, I don't think that is possible. If you disable OneDrive for users Teams will use OneDrive for file sharing in chats anyway. If you disable Sharepoint for users, Teams will use Sharepoint anyway for sharing in Channels.
If you disable Team creation for users and don't create any Teams and don't create any Teams for them, they won't be able to create Teams. And if you disable Chat they won't be able to chat and share files there. But then I don't see why you want to use Teams.
Why do you want to stop users from collaborating with files?
To prevent data loss in the organization.
- data loss is a complicated thing, all the answers here is the way to stop share, they can't prevent loss.
if you are an engineer, yes, do these things because it's a job
if you are a manger or want to RCA, classify data, let people know how and why. these functions in machine is the last thing you need as tips.- Thanks, the question raised was on blocking sharing so I would expect solutions on blocking sharing, not data loss. If you want to stop data loss on the device, use endpoint DLP, WIP or app protection policies, or even better, transition to AVD/Windows 365 and remove the hardware out of the question, nothing will be able to be copied onto the device connected to the session.
I would say it is better to use the data loss prevention and disable external sharing (read the links from Chris) instead of disabling file sharing. File sharing and working with files together in Teams is a big part of Teams.
