"Open in App" allows read-only files to be written
Hello!
We currently have one Microsoft Team, where we needed to restrict one of the folders of the General channel to be read-only, so members of the team can only view the PowerPoint slides we have inside. We removed the inheritance of permissions of the folder directly in SharePoint, and permissions now show that Team Owners have full control, and all the rest (Team Members, Team Visitors, and some other groups) should have "Can View" permissions.
The behavior we are experiencing is that when one of the users from the "Can View" groups open one of the PowerPoint files in the browser, the file is opened as read-only (which is the expected behavior). But, if they click "Open in App" the PowerPoint desktop client opens, and they can modify and save the file (and this is overwriting the source file where supposedly they only have read-only permissions).
Is there a setting or something we are missing to prevent this?
Any help will be appreciated.
Thanks

Hi Juan Sueiro ,
The SharePoint permissions model is pretty robust, worth finding the file in SharePoint, viewing its permissions and use the Check Permissions function on the advanced permission screen to check against some users. If that still says the user or users in question only have View I would be surprised.
The only thing that would overwrite that is Site collection Admin permissions.
Kind regards

- I am actually having the same issue as described. Double checked everything. Opening in desktop app makes the file editable.
