ThunderBird will prompt you for the very basic settings when you first launch it

**If you are not launching it for the first time and need to add an account you will go to File>New>Existing Account**

You should see something like this: 



Put in your first and last name, your email address, and Control Panel password. 

Then you will press continue, Thunderbird will now try to autoconfigure itself. In most cases this will not work and you will see the following message:
