This is the script that worked for us - maybe, something here will help? smtp_host = 'smtp.office365.com' smtp_port = 587 smtp_user = 'whate...@yourdomain.com' smtp_pwd = 'whatever-your-password-is' smtp = Net::SMTP.new(smtp_host, smtp_port) smtp.enable_starttls_auto smtp.start("yourdomain.com", smtp_user, smtp_pwd, :login) smtp.send_message(msg, smtp_user, to_mail) smtp.finish For reference, the start method uses this structure: > start(helo_domain, account, password, authtype) It was important for us to: > make sure the smtp host was smtp.office365.com = yours seems OK > port was 587 = yours seems OK > STARTTLS was AUTO = yours seems OK > make sure that the smtp.start used "yourdomain.com" = not sure if you're doing this > authentication was LOGIN = yours seems OK Hope this helps. Best Regards, Mohit.
