If authentication is required and you haven't logged in yet, specify your login details by clicking "Grammarly" on your Word toolbar -> "About" -> "Proxy settings". If after submitting your Grammarly login and password you see an error message that says, "Proxy authentication required", click "Proxy settings" to specify your login details.
