Hi @Terry Chan ,
Is there way to restrict user upload file to a team channel?
Currently, there's no option from within Teams to prevent users from uploading files to a team channel. However, if you are the team owner, you could go to SharePoint and modify the permissions there:
- Click "Open in SharePoint" in the Files tab of the team channel:
- Login SharePoint and click "Manage access" on the right pane.
- Change the permission of members to "can view".
Then the members would not be able to upload files into the channel any more:
