Is it possible to disable or hide the “Insert files using Drive” (the Drive icon) button in the Gmail compose window through the Admin Console?
Our organization wants to enforce a stricter security policy where users share files via secure Drive links instead of sending them as attachments. Sending a link provides better control, such as the ability to revoke access and ensure everyone is viewing the latest version. Attaching the file from Drive creates a separate, uncontrolled copy.
How can we force users to share links only?
