How can this error be fixed?  It works fine in Thunderbird. 

Hello,

It is very common to receive the error message 0x800CCC0E when configuring an email account in MS Outlook & trying to send an e-mail, the reason why you get the error is because MS Outlook is not authenticating your account on the server while sending it, so the outgoing mail server rejects the message. While searching over the internet I found an informative article to resolve this error.
