You can follow the steps below to configure Mozilla Thunderbird to connect to an email account that has been created via cPanel. This guide assumes you have already created the email account.

1. Log into cPanel and click on the "Email Accounts" icon.

2. Click on "Connect Devices" next to the email account you are looking to configure.

3. You will then be able to see the settings that you can use to connect your email client. There are both secure and insecure options, we highly recommend you use the secure settings. Keep this page open as you will need to enter these settings in your email client.

4. Open up Thunderbird and click on "Tools" and "Account Settings".

5. At the bottom of the window click on "Add mail account".

6. You will then be asked to enter the connection details for your mail account. The details you need to enter are those that you found in step 3, so go back to cPanel and enter the correct details. Please note that the screenshot below is used as an example only and the actual connection details you need to enter can be found in your cPanel.

You have the option of selecting which type of email account you would like to set up. You have two options:

- IMAP
- POP

An IMAP connection is recommended if you plan on accessing your emails on multiple different devices as this leaves all mails on the server. A POP connection would, by default, download all mails to your local machine and then remove them from the server meaning they couldn't be accessed from another device.

Assuming you have entered the connection details correctly you will see a success message after clicking "Done" and your email account is now ready to use in Thunderbird.
