My hotmail id is *** Email address is removed for privacy ***. Some of my friends are trying to send me the mails but the mails are bouncing back saying my inbox is full. I have noticed that if they send me the mail from their official id (official server) then the mail bounces back but if they send me the mail from servers like hotmail, rediffmail, yahoo the mail do not bounce back and I got the same. 

Please advise the solution.
