Properly configure Thunderbird on Windows can save you a lot of headaches, especially if you manage multiple email addresses or work from different devices. Checking email is almost as common as checking your phone these days. That's why having a powerful, flexible, and free tool like Thunderbird, developed by the Mozilla Foundation, is a real advantage.
This complete email client, available for Windows, is a favorite for both personal and business users, thanks to its ease of use, customization options and securityIf you've never used it, here's everything you need to know.
Download and install Thunderbird on Windows
The first step to having Thunderbird on Windows is to download it to your computer:
- Access the Thunderbird official page (thunderbird.net) from your favorite browser.
- The system will automatically detect your version of Windows and show you the appropriate installer. Just click the download button, wait a few minutes, and then run the downloaded file.
- Follow the steps in the installation wizard, which is designed to be as simple as possible. In just a few moments, you'll have the Thunderbird icon ready on your desktop to start using it.
What information do you need to set up your email in Thunderbird?
Before you open the app and start setting up your email, there are a few things you should know essential data that you should have on hand:
- Full email address.
- Email account password.
- Information about your incoming and outgoing mail servers (IMAP/POP3 and SMTP), especially if you have a corporate email or a custom domain.
For popular accounts like Gmail, Outlook, and most major providers, Thunderbird usually automatically detects the settings. If your email is from a specific hosting provider (e.g., Hostinger, Dinahosting, OVH, etc.), check your provider's control panel for the details, usually accessible in sections like "Emails," "Mail Accounts," or "Manual Configuration."
Getting Started with Thunderbird: Adding an Email Account
When you open Thunderbird for the first time, you'll be guided through a wizard to add your first account. If you already have accounts set up and want to add another one, just go to Menu (three-stripe icon, top right) > New Account > Email.
The wizard will ask you for this information:
- Full name (this is the name that will appear as the sender to the recipients).
- Full email address.
- Password (you can check the option to remember it and not have to enter it every time).
Enter your details and click 'Continue.' Thunderbird will automatically attempt to locate your server settings (it may take a few seconds).
Automatic configuration: for popular accounts and well-known providers
In most cases, Thunderbird will automatically detect the necessary parameters to get your account ready in just a few clicks. You'll usually be given a choice between IMAP or POP3 for incoming mail. Select IMAP if you want to keep your mailbox synced and click "Done."
If the setup completes without errors, you'll see your inbox ready to start receiving and sending emails immediately. To add more accounts, repeat the process from the corresponding menu.
Manual setup: Own domain accounts or advanced settings
If your email provider is not listed in Thunderbird's automatic database, or if you have very specific needs (for example, advanced encryption, special authentication, or custom servers), you will need to do the following: manual configurationThis process is just as simple if you have the data on hand:
- Open Thunderbird and go to New > Existing Email Account.
- Enter your basic details (name, email, and password), but instead of continuing, click 'Set up manually.'
Configuring the incoming server (IMAP or POP3)
- Choose your preferred protocol (IMAP or POP3).
- Enter the server name (for example: imap.yourdomain.com or whatever your hosting provider tells you).
- Enter the appropriate port (IMAP is usually 993 for SSL/TLS; POP3 is usually 995).
- Select the encryption type: SSL/TLS is the most common for maximum security.
- Authentication Method: Select 'Normal Password' unless otherwise specified by your provider.
- Username: For many hosting providers, the first part of the email address is sufficient (e.g., 'admin' in admin@yourdomain.com), but in other cases, you must enter the full address. Consult your service's instructions.
Configuring the outgoing server (SMTP)
- Enter your provider's SMTP server name (example: smtp.yourdomain.com).
- Usual port: 465 for SSL/TLS, although 587 is sometimes used for STARTTLS.
- Security Type: Select SSL/TLS or STARTTLS as directed.
- Authentication method: usually 'Normal Password'.
Once you've completed this information, click "Recheck" to have Thunderbird on Windows validate your settings. If everything is correct, click "Done" to complete the process.
Setup with oAuth: essential for Gmail and some corporate services
Some providers, especially Google with gmail, require that authentication be performed by oAuth, a more secure system than the traditional username/password combination. The procedure is very similar:
- Enter your name, email address, and password.
- Instead of automatic validation, a window will open asking you to grant access to Thunderbird using your Google account (or the corresponding provider).
- Follow the login flow in the pop-up window until you are prompted to grant permissions.
- Once you're done, the account will be configured, and you'll be able to check in Thunderbird's settings that the authentication method is 'oAuth2' on both the incoming and outgoing servers.
If for any reason auto-detection doesn't work, you can choose 'Configure manually' and select 'oAuth2' as your authentication method when entering your server and port details.
Customization and advanced settings in Thunderbird accounts
Once you have your accounts added, you can customize them thoroughly from the menu. Account settings (which appears when you click on your email in the left column and then on 'Account Settings' in the top right):
- Name and personalized signature: Change the name that appears as the sender or add a personalized signature to your emails.

- Sign via file or vCard: Automatically attach a signature file or your contact card.
