Tired of paying for expensive but trashy conversion software? Our guide shows you how to convert your MBOX files to PST format using free tools. With our quick and easy steps, you’ll be up and running in no time.

What are MBOX and PST file formats?

MBOX and PST are file formats used for storing email messages. MBOX is the standard format used by many email clients, such as Mozilla Thunderbird and Apple Mail, while PST is the proprietary format used by Microsoft Outlook. Furthermore, MBOX files store email messages as individual text files, while PST files store them in a proprietary binary format.

Why do you need to convert MBOX to PST?

There are several reasons why you might need to convert MBOX to PST. One common reason is when you switch from an email client that uses the MBOX format to Outlook, which uses the PST format. Another reason is when you need to share email messages with someone who uses Outlook or when you want to backup your email messages in PST format.

Tools you need to convert MBOX to PST for free

To convert your MBOX files to PST format for free, you will need the following tools:

  • Mozilla Thunderbird – open source email client that supports MBOX files.
  • ImportExportTools Thunderbird Add-on – an add-on that allows you to import/export MBOX files.
  • Microsoft Outlook – to import the EML files into PST format.

Step-by-Step Guide: How to Convert MBOX to PST for Free

Follow these steps to convert your MBOX files to PST format for free:

  1. Install Mozilla Thunderbird.
  2. Install the ImportExportTools NG add-on in Thunderbird.
  3. Import your MBOX files into Thunderbird using ImportExportTools NG ass-on.
  4. Select the MBOX folder you want to export and choose “Save selected messages” from the right-click menu.
  5. Choose the export format as “EML“.
  6. Open Microsoft Outlook and create a new folder to store the MBOX emails.
  7. Select the EML file, right-click on it then select Open with >> Outlook.
  8. Once the email opens in Outlook, click on “Move” from the ribbon bar, then choose the new folder.
  9. Make sure to repeat the previous two steps for each EML file.

Do You Know?
The drag-and-drop method showcased by many brands online to convert MBOX to PST is actually a hoax. When you drag and drop EML files into Outlook, it is not treated as an email. In fact, when you double-click to try and open this “email”, you will be given the option to open it or save it to your computer. Here, you need to open it with Outlook (Outlook must be the default app to open an EML file), then save it to make it an integral part of Outlook.

At last, all your emails are successfully transferred to Outlook. Now, if you specifically want to move all MBOX data to a PST file, then simply create a PST file in Outlook, described below.

Another Way to Convert Your MBOX File to PST Without Spending a Cent

You will require a Yahoo mail account ending with @yahoo.com (preferably new) in addition to the tools you needed for the previous method. Once you have that, get on with the following instructions to change your MBOX files into PST format.

    2. Outgoing mail server: smtp.mail.yahoo.com
    3. Port: 993 (IMAP) or 995 (POP3) for incoming mail, and 465 for outgoing mail.

  3. Select all the emails in the imported folder and copy them into the new Yahoo folder.
