Traditional Approach To Convert MBOX to PDF

MBOX emails can be saved in PDF format through various methods. One can opt for a manual way or a dedicated converter tool. Prior to opting for any conversion process, it becomes necessary to comprehend both ways to prevent any problems related to data.

Using Thunderbird to Convert MBOX File to PDF

Here, one needs an email client that is capable of supporting MBOX. Once the software is installed, one can proceed as follows:

  1. Start the Thunderbird application on your system first.
  2. After that, click on the Tools menu option and then select the Add-ons and Themes option.
  3. Following that, enter ImportExportTools NG in the add-ons tab.
  4. Further, after searching for it, install it.
  5. Moving ahead, start the software again to make the changes.
  6. Once done, locate your mailbox in Local Folders from the left panel.
  7. Afterwards, right-click the folder where your emails are stored.
  8. Then, select the option ImportExportTools NG.
  9. Choose the Export All Messages in Folder menu item from the menu list.
