I am trying to figure out how to send and receive e-mail through Windows mail, not webmail. The WebMail works fine. I am currently outside of a Cox service area, so the internet supplier I am using at the moment is not Cox. My SMTP setting that previously worked fine will no longer send e-mails. I can receive just fine, but it says "The connection to the server has failed" when attempting to send.
I would suggest checking out Step #4 under the Live Mail setup section for SMTP settings that should work for you. Please disregard the IMAP reference.
