To configure your mail accounts in Mozilla Thunderbird, follow these steps:
- Open Mozilla Thunderbird.
- Access the Tools > "Account settings". You will see a column on the left side with a dropdown menu at the bottom. In the dropdown menu select the "Add mail account... option.
- You should now fullfill the Account Identity. In the first blank space put your name, in the second, the email address you are configuring
- Clicking the Next button will prompt you to choose between an IMAP or POP connection. Choose the one you prefer and hit the Done button. The system will check the settings and configurations to return to the "Account Settings" section.
Once these steps are done the account should work correctly. You will see on the left side the different folders of the mailbox.
