The following is the error message I receive:

"The message could not be sent.  The setting for your outgoing email (SMTP) server might need to be configured.  To find the server settings for "(I tried several addressees)' please contact your email service provider.  Server error 554.  Server Response 554 5.7.1 (R8) Authentication Failed, must login.  Server 'smtp.q.com'.  Windows Live Mail Error ID: 0x800ccc79   Protocol SMTP   Port: 25  Secure (SSL): No."

Now my centrurylink provider's email program is/runs/sends fine (they checked it out and referred me back to M'Soft).  M'Soft blew me off 4 times, so am seeking help from the community.  I have read all posts (you guys are pros) and tried a few things (like fixing W Essentials), but nothing matches my error message.  Am using Win 8.1, and my wife prefers WLM but can't send.  I use the q.com (CenturyLink) email.  (Would appreciate a CC: response at that linked address:  *** Email address is removed for privacy *** as well). 

I think it is the set up for WLM (Port 25 doesn't look right).  Login shouldn't be a problem, as when I open my computer each morning I sign in to the computer with *** Email address is removed for privacy ***, so I don't understand  error msg "failed, must log in".

Gratefully appreciate your help.
