Files that are identified to be violating Google's terms of service can be restricted from use. This can happen for a number of different reasons.
When a file is determined by Google to be in violation, an email will be sent to the owner's g.syr.edu Gmail account that will notify them of the action taken and instructions on how to review the restriction and potential actions that can be taken.
There is no admin control of this policy. This means that Syracuse University Google Workspace admins have no ability to review or take action on behalf of the user. Admins also have no access to the user's data.
