One time, when I had to use outlook, someone called me asking why I wasn't replying to emails since like 3 days. Turned out Outlook had decided I could receive emails, but when I was replying, the email would put in a special folder "to be sent" or something, because the MS outgoing server was not working. I looked like a fucking imbecile when I figured it out and tried to explain what happened.
