Thunderbird to Outlook: Manually Convert MBOX to PST Files

Manually converting Thunderbird MBOX files to PST (Outlook Personal Storage Table) files involves several steps. Here's a step-by-step guide on how to do it:

Step 1: Export MBOX Files from Thunderbird

  1. Open Mozilla Thunderbird on your computer.
  2. Select the email folder you want to export. This can be your Inbox, Sent items, or any other folder.
  3. Right-click on the selected folder and choose "Export As" from the context menu.
  4. Save the folder as an MBOX file to your desired location on your computer.
  5. Repeat this process for all the Thunderbird folders you want to convert.
Step 2: Download and Install Mozilla Thunderbird

If you don't have Thunderbird installed on your computer, you can download and install it to use its built-in Import/Export tools for the conversion.

Step 3: Convert MBOX to EML Format

  1. Open Thunderbird and create a new email account.
  2. Drag and drop the MBOX file you want to convert into the Thunderbird email account. This will import the MBOX file into Thunderbird as an email folder.
  3. Select the imported folder in Thunderbird, and then right-click and choose "Save as" to save each email as an EML file to your computer. This will convert the MBOX file to EML format.
  4. Repeat this process for all the MBOX files you want to convert.
Step 4: Convert EML to PST Format

To convert EML files to PST format, you can use a third-party tool or Microsoft Outlook (if you have it installed). Here are two methods:

Method 1: Using Microsoft Outlook (Requires Outlook Installed)

  1. Open Microsoft Outlook.
  2. Create a new folder where you want to import the EML files.
  3. Drag and drop the EML files into the newly created folder in Outlook.
  4. Outlook will automatically import the EML files, and you can now export them to a PST file.
  5. Go to "File" > "Open & Export" > "Import/Export."
  6. Choose "Export to a file" and click "Next."
  7. Select "Outlook Data File (.pst)" and click "Next."
  8. Choose the folder that contains the imported EML files.
  9. Specify the location and name for the PST file, then click "Finish" to complete the conversion.
Method 2: Using a Third-Party Tool

There are various third-party tools available, such as "ATS MBX to PST Converter," that can directly convert All Types Of MBOX files to PST format. Download and install one of these tools, follow the on-screen instructions to import the EML files, and then convert them to PST.

By following these steps, you can manually convert Thunderbird MBOX files to PST format using Mozilla Thunderbird and, if necessary, Microsoft Outlook or a third-party conversion tool.
