Hi there, for last 6 months I was using Mozilla Thunderbird without any problems. Month ago I seen that Messages from me to someone are sent successfully, but messages from someone to me are not coming. I Checked settings and they were fine it just happend one day... before that everything was working good. When I wanted to remove this account from Mozilla Thunderbird and create new one ( it says wrong login or password ) password is for 100% good because I was using it manually to collect e-mails from web and was working. After 4 h of trying different things I surrender and I installed outlook and same password and login was working perfect. Today my Boss have the same problem as me described above can sent e-mails but can't receive them back. And he is also not able to create new Account because Mozilla says that Login or password is wrong.... what to do with that.....
