What to Do If Thunderbird Doesn’t Work with Gmail Workspace

1. Enable IMAP Settings – If Thunderbird Not Working on Gmail

For Thunderbird to sync properly with Gmail, the first step is to set up IMAP.

Enabling Gmail IMAP settings allows Thunderbird and Gmail to fully work together.

Enable IMAP access by following these steps:

  1. Firstly, Open your Gmail account.
  2. After that, click on the Settings tab in the upper right corner.
  3. Go directly to the “Forwarding and POP/IMAP” section.
  4. In the IMAP Access section, select Enable IMAP. Finally, click “Save Changes”.

  1. Firstly, right click on the Gmail account that has the problem.
  2. Then, select “Account Settings” in the upper right corner.
  3. On the tabs on the left, click “Server Settings” to check them in detail.

4. Make Changes to Antivirus Software Settings

If the antivirus software installed on your computer classifies Thunderbird as a potential threat, it restricts the sending and receiving of emails through it. This could be the reason why email is blocked and Thunderbird doesn’t work well with Gmail. Follow these steps to change antivirus settings.

  1. Go to “Settings” on your system.
  2. Then, Under Update & Security, click Windows Security.
  3. Click Virus & threat protection, then click Manage settings.
  4. Under Add or remove exclusions, click Add exclusion and finally select Thunderbird.

5. Downgrade to a Previous Version of Thunderbird

If your service provider does not support the current version of Thunderbird, it is recommended to roll back to the previous version. This will solve the Thunderbird not working with Gmail issue.

6. Switch to a Different Email Client

Thunderbird uses MBOX formats to store emails. However, other email clients like Outlook have a wide range of features and users can migrate to them. To access MBOX in Outlook, the files need to be converted to PST format, which is a much more advanced format. PST files have better security features and even support multiple data types including emails, contacts, tasks, calendar, and notes. Converting an MBOX file to a PST file is difficult and must be done carefully and with accurate information about both types of formats. Even with a professional tool, the process can be complete in a very short time. One such tool is BitRecover MBOX to PST Converter Tool, which can easily convert MBOX to PST format. It is ideal for users who do not have the level of technical knowledge required to perform the task using manual methods.

7. Backup Data to Drive

A backup option is the first thing we recommend, as when you start an experiment you should save your available data. So, save Thunderbird data in to your backup drive.
