E-mails in windows 8.1 mail app not being sent [Windows 8.1 Email and Communications Mail app]

hi I am having problems setting up an outlook e-mail address in windows 8.1 mail app. My inbox will receive and display emails as received but I cannot reply to these e-mails or send to a known e-mail address. Outlook generates an indeterminate number of sent e-mails that exceeds the daily message limit and then provides me with a rejection message saying e-mail has not been sent. I know I have the correct alias set up for the account but the server configuration or some other problem is causing the system to fail...please help!
