I've got two servers : Edge and BackEnd ( Mail box / hub ) I have supplied the product key to both and both have taken the key successfully and both are licensed. When i open Exchange Management Console on backend it still shows that other server is not licensed. But when i open the Exchange Management Console on Edge itself, it shows no such error ? I have restarted the Edge sync service, have restarted both servers, but still when ever i start Exchange Management Console on Backend it shows me that other server is not licensed Any idea ?
