• Microsoft Outlook installed (for saving as MSG).

Step 1: Import MBOX into Thunderbird

1. If you haven’t already, download and install Mozilla Thunderbird from the official website. 
2. Go to the menu (three horizontal lines in the top-right corner).
3. Select the Add-ons and Themes option.
4. In the Add-ons Manager, search for ImportExportTools NG add-on.
5. Click the Add to Thunderbird option and follow the prompts to install it.
6. Restart the Mozilla Thunderbird application.
7. After clicking on the local folder option.

10. Browse to locate your MBOX file and select it.

2. Click on the email you wish to convert to highlight it.
3. To select multiple emails, hold down the Ctrl key (on Windows) while clicking on each email you want to select.
4. Once you have selected the desired emails, click and hold on one of the selected emails.
5. Drag the highlighted emails to your desktop or into a specific folder on your computer.
6. Release the mouse button to drop them. This action will save the selected emails as individual EML files in the chosen location.

Now that you have your emails saved as EML files, you can proceed to convert them to MSG format in Outlook. 

Step 3: Convert EML to MSG in Outlook

1. Launch the Microsoft Outlook (Classic) application on your computer.
2. Find the folder where you saved the EML files.
3. Then, select the EML files you wish to convert.
4. Drag and drop the selected EML files directly into an Outlook folder (like your Inbox or any other folder).
5. After dropping the files, the EML emails will appear in the chosen Outlook folder. They are now accessible within Outlook.
6. To save the imported emails as MSG files, double-click to open each email in Outlook.
7. Navigate to the File menu in the top-left corner.
8. Select Save As from the dropdown menu.
9. In the Save As dialog box, select the desired location on your computer.
10. In the Save as type dropdown, select Outlook Message Format (.msg).
11. Click Save to store the email in MSG format.
12. If you have more EML files to convert, repeat the steps above for each email.

Now you should have your emails successfully converted from MBOX to MSG format.
