i'm getting the same error message. anyone have an answer?
In Windows Live mail, I get Server Error 503, Server Response, 503 STARTTLS command, used when not advertised. Windows Live Mail Server 10:0x800 CCC65. Protocol SMTP. Port 587, when I synchonize.
Most messages come in find. I seem to get the above error more when forwarding or replying to emails vs. creating a new one and sending.
Any ideas for fixes? Thanks.
