I have sent emails from my Hotmail account to my other email accounts, and they all received them perfectly. No problem there. When I replied to the Hotmail account, the email never showed up in the inbox. Same when I simply sent a new email directly. I have also forwarded emails from two other accounts to my Hotmail account with not one of them being delivered to my Hotmail inbox. I also have had friends send emails to my Hotmail account but none of them have been delivered either. I have checked all settings and there is nothing other than the standard spam filter in effect. So far, no positive results.
