Various Approaches to Export Thunderbird to EML Format

Once the user reviews the reasons users consider exporting their Thunderbird emails to an EML format, let’s proceed. Now, we will execute the solutions that successfully export the emails to the EML file format.

Approach 01: Using Drag and Drop

This approach is the easiest of all to convert Thunderbird to EML format. The Thunderbird email client automatically saves the email messages in EML when they are dragged to a local folder.

Use the following instructions to begin the process;

  1. Launch the Mozilla Thunderbird application.
  2. Then, head to the mailbox containing the emails you want to convert.
  3. After that, select the email(s) you want to convert and then drag and drop them from Thunderbird to a local folder.
  4. The emails will be saved as .eml files in the local desktop folder.

Limitations: The approach cannot be used to convert large Thunderbird mailboxes to EML format. It also does not preserve the original folder structure. Also, there is a high possibility of human errors while manually performing the steps.

Approach 02: Via an Add-on ImportExportTools NG

Users can simply export emails from Thunderbird to EML by downloading the ImportExportTools NG in Thunderbird. This add-on enables users to export single or multiple emails to EML at once. 

Look at the steps to start the export process:

  1. Open the Thunderbird application on your system.
  2. Navigate to Tools > Add-ons and Themes and then search and install ImportExportTools NG.
  3. After that, restart Thunderbird and right-click on the folder containing emails you wish to export.
  4. Next, select ImportExportTools NG > Export all messages in the folder > EML format. 
  5. At the end, pick the destination to save the resultant exported EML files.

Limitations: There can be issues with compatibility if the add-on does not match the Thunderbird version. Exporting large Thunderbird emails will take a considerable amount of time.
