Fix: Error from Mail client: "Web login required …”

Published on July 20, 2011

I encountered an error from my Mail client, a couple of times. The error message is

Error from Mail client: “Web login required: (Failure)”

I am not exactly sure what is causing the error to my Mac Mail client. But I do know how to fix it by unlocking captcha.

To fix, you have to go to, enter your email address and password (works for enterprise app too), and it will miraculously solve the error.

Note: If you will to go to, it will ask you to go to That link somehow doesn’t work.
