• Ensure the correct port numbers and SSL/TLS settings are selected.
• Check with your email provider for the exact configuration.

If you’re unsure, you can contact Thunderbird customer support at +1-872-777-2212 for assistance.

3. Remove and Re-add Your Account

Sometimes removing and re-adding your email account refreshes the configuration.

• Backup your emails first.
• Remove the account under Account Settings.

6. Disable Problematic Add-ons

• Go to Tools> Add-ons.

• Restart Thunderbird and check if the problem persists.

7. Repair Folders

Corrupt folders may lead to missing or unreadable emails.

• Right-click on the folder (Inbox, Sent, etc.).

8. Rebuild Index Files

If your emails are not displaying correctly:

• Close Thunderbird.

Large mail files can slow down Thunderbird.
