Windows Live Mail 2012 on the Windows 8.1 operating system

I have serveral computers with the Windows 8.1 OS. I absolutely do not like the Windows Outlook mail that comes with 8.1. I installed Windows Live Mail 2012 onto the computers. I have entered in the proper information for incoming and outgoing mail in the Live Mail 2012 but when trying to send a message I get an error message saying it cannot locate my POP3 host. But it appears that I can receive a message in the Live Mail 2012 using the smtp configuration. Does Windows Live Mail 2012 work in the 8.1 OS?  If it can work then how do I get it to send out emails.
