Exporting Thunderbird mail can be done by following these steps:
Launch Thunderbird: Open the Thunderbird email client on your computer.
Select the folders: Choose the folders that you want to export. You can export individual folders or the entire mailbox.
Create a new folder: If you want to export specific folders, create a new folder in Thunderbird and move the desired emails into it. This step is optional if you want to export the entire mailbox.
Install an export add-on (optional): Thunderbird doesn't have built-in export functionality for emails, so you may need to install an add-on to facilitate the process. There are various add-ons available that provide export capabilities, such as "ImportExportTools NG" or "ImportExportTools".
Install the add-on (if necessary): If you opted to use an add-on, follow the installation instructions provided by the add-on developer.
Access the export functionality: Once the add-on is installed (or if you're using Thunderbird's built-in functionality), go to the "Tools" menu and look for the export option. The location may vary depending on the add-on you installed.
Configure export settings: Choose the format in which you want to export the emails. Common options include mbox, EML, or CSV formats. Select the destination folder where you want to save the exported files.
Start the export process: Initiate the export process and let Thunderbird or the installed add-on export the selected folders or mailbox to the specified location.
Verify the exported files: Once the export process is complete, navigate to the destination folder and verify that the exported files are present and contain the desired emails.
It's important to note that the specific steps and options may vary slightly depending on the version of Thunderbird you are using and any add-ons you install. Always refer to the documentation provided with the add-on or consult the Thunderbird support resources for more detailed instructions.
