Error: Unable to send or receive messages Server Error 3204 in Windows Live Mail

I am having this issue with my Windows Live  Mail desktop application. It started with an issue of a"loop" of trying to connect to my calendar. Saw this at the lower right corner of the application.  I disabled the "sign-in feature" and that fixed the "loop" but still doesn't connect to mail server.  I get the Error message "Error: Unable to send or receive messages Server Error 3204."  I looked for an answer in this forum and tried the various fixes - Deleting accounts and re-creating, adjusting the connection to the internet, checked for firewall interference, repaired Live essentials.  None of these did the trick. Can someone please assist me as well?  Thank you.
