This is all to do with Google's servers and their services, so I can't help you much. The 403 error code means "Forbidden", so it looks like a problem with permission. The error message seems to mention the "domain administrator", so try talking to them if that's applicable.
this is due that any file being saved to G-drive is being flagged for abuse. This is concerning with terms and services of google new policy and sharing is automatically disabled and hence the message. review of Terms of Service may help to correct the issue.
