- Reconfigure Server Settings: Verify that your incoming and outgoing server settings (IMAP/POP3 and SMTP) are correct. You can find these details on your email provider's help page.
- Check for Server Downtime: Sometimes, the issue may not be on your end. Verify if the email provider’s servers are down by visiting their status page.

- Create a New Profile: If the current profile is corrupted, creating a new profile may solve the issue. You can do this by using the Profile Manager.
3. Corrupted Profile
- Use the Profile Repair Tool: Thunderbird includes a repair tool that can help fix certain profile-related issues. You can access it from the "Tools" menu.

5. Unable to Send Emails
