Hello!  I'm having the same (or similar) problem as others here.  I'm not very computor savvy, and do not understand much of the advice given so far.  For example, I went to the page "How do I add an account to Windows Live Mail?" as advised in the message above, and can't see that it tells how to "reconfigure" my e-mail account.  

I use Windows 7.  Windows Live Mail has worked for me for years.  Now, suddenly, I can receive but not send.  The messages I've tried to send do exist; they sit in my Outbox.  I've tried to send to another of my accounts, and the messages don't arrive. 

The error message shows an exclamation mark in a yellow triangle.  It says (I'm translating here from the Norwegian):  "There were some problems....  See below if you want more information."

Then there is a long green bar.  It starts over now and then, and fills up quickly.

In the box below  it says (translating again): 

Delete the e-mail with image, form a new one and try to send it again. 

Server: 'smtp.online.no'    Windows Live Mail Error-ID: 0x8CCC0003

Protocol: SMTP, Port 25, Sure/safe (SSL): No

Not all the messages in my Outbox contain images; just the first one.  It's strange that the ones without images don't go through, if the image is the problem.

I hope someone will be able to help me fix this, giving VERY clear instructions.  Thank you.
