I am not sure about it but I think hotmail is having serious server problems , I am trying to send some emails and then it comes that delivery failure or mail server is busy ?? Are you having the same problem too ? Some of them are sent corectly but the others not. The email adresses are correct and they don't have their email full. Any Help ?
Hello! Actually, I've had a friend send me some mails, and he complained about this as well. It may be a temporary bug.
