I have had the same problem. I check the authenticate boxes. None of my ISP's
match the pop domains but I have been successful sending before. I monitor
multiple email addresses from one Outlook profile. I like to respond to
emails with the same domain they sent the email to. It seems to work from one
partition but not from the other (same ISP). Settings are all the same. Any
thoughts?

Usually not random, but if you have more than one account and you send a
message with an account whose address is in domain X using domain Y's mail
server, you'll see the problem. As you move your laptop from one place to
another, the ISP you're using changes. When you're using an account where
the sender address domain matches the ISP, the mail goes through.
Otherwise, it doesn't.
