  • Backup Your Data: Always a smart move! Use an MBOX backup tool to protect your data from loss during the import process.
  • Add the Import Export Tools Add-on: This handy add-on simplifies the import process. Make sure you have it installed in Thunderbird before proceeding.

FAQ

Ques1. How do I import MBOX files into Mozilla Thunderbird?

Ans. To import MBOX files into Thunderbird, you need an add-on called ImportExportTools NG. First, install the add-on by going to Tools > Add-ons & Themes, then search for ImportExportTools NG and install it. Once installed, right-click on your inbox (or another folder), select ImportExportTools NG > Import MBOX file, and choose the MBOX file you want to import. Follow the prompts to complete the import.

Ques2. Can I import multiple MBOX files at once into Thunderbird?

Ans. Yes, with the ImportExportTools NG add-on, you can import multiple MBOX files in one go. When using the import option, you can choose to import a directory containing multiple MBOX files. This allows you to bulk-import emails without having to handle each file individually.

Ques3. Will my emails and folder structure be preserved when importing MBOX files into Thunderbird?

Ans. In most cases, Thunderbird preserves the emails and folder structure during the MBOX import process. However, it’s a good idea to double-check the folders after the import. If something looks off, you can manually reorganize your folders within Thunderbird.

Ques4. Can I import MBOX files into Thunderbird without an add-on?

Ans. Thunderbird doesn’t natively support importing MBOX files without an add-on. To make the process seamless, it’s best to use ImportExportTools NG. Without this, Thunderbird won’t recognize MBOX files directly, so using this trusted add-on makes the process much smoother.

Ques5. What should I do if my MBOX file is too large to import into Thunderbird?

Ans. If your MBOX file is too large and causing issues, try splitting it into smaller parts using an SoftMagnat MBOX splitter tool before importing it into Thunderbird. Large MBOX files can sometimes slow down the import process or cause Thunderbird to hang, so working with smaller chunks can help ensure a smoother import.
