In this article, we’ll explore three reliable and free ways to export your MBOX data to the PST format used by Outlook. While some of these methods can require additional technical skills, they offer a useful solution for moving your mailbox to Outlook. Let’s start by understanding the differences between MBOX and PST file formats, which are generated by various email clients on your local system.

While Outlook PST files contain multiple types of data, such as contacts, calendars, tasks, etc., MBOX data files are primarily used to store email and this difference can require several different processes and easy changes.

Motivations and Benefits of Data Migration From MBOX to PST:

  1. Data collection: Outlook makes it easy for users to access and manage their information in a single PST file by consolidating data sets.
  2. Comprehensive security measures: Outlook has strong security measures that ensure your data is protected and controlled for access.
  3. Exchange Server integration: Outlook users can easily work in offline mode thanks to Outlook and Exchange Server interoperability.
  4. Beautiful Features: Outlook has many features that you can not find in other email applications, such as calendar sharing, time sharing, keyboard shortcuts, email settings, and creating rules

Let’s now examine the three free ways to convert MBOX files to PST:


Method 1: Using Gmail or another online email client

This technique makes use of Gmail as a middleman to make the transfer from MBOX to PST easier. It uses the IMAP protocol and includes three stages. Note that email clients connected to MBOX and Outlook need to be installed on your system.

Step 1: Set Up a Gmail Account to Use IMAP Protocol

  • Click the Gear icon after accessing your Gmail account.
  • After choosing “See All Settings,” select “Forwarding and POP3/IMAP.”
  • Turn on IMAP and save your changes.
  • Go to “Less secure app” and activate it.

Phase 2: Use the IMAP Protocol to migrate MBOX to Gmail (Using Mozilla Thunderbird as an Example)

  • Launch Mozilla Thunderbird and choose the Account section’s “Setup an email account” option.
  • Enter your password, Gmail address, and name. Press “Continue.”
  • After selecting IMAP, click “Done.”
  • Verify your login information, then use Thunderbird to create a new folder beneath your Gmail account and import your emails into it.

Phase 3: Use the IMAP/POP3 Protocol to configure Gmail to Outlook

For the 2007 Outlook:

  • Select “Tool” from the menu, then “Account Settings,” and finally “New.”
  • Proceed after selecting “Microsoft Exchange, POP, IMAP, or HTTP”.
  • After selecting “Manual configure server and additional server types,” press “Next.”
  • After providing the necessary information, select “Test Account Settings.” If everything goes well, Outlook will include your MBOX files. If it doesn’t work, choose “My outgoing server (SMTP) requires authentication” under “More Settings.”
  • Set the SMTP to 25 and the IMAP server to 993 or 143 under the Advanced tab. Once more, check the account settings by clicking “OK”.

Regarding Outlook 2016/2019:

  • Select “Info,” then “File,” and then “Add Account.” Select “IMAP.”
  • After entering the required information, select “Next.”
  • Before connecting, configure the incoming and outgoing mail ports.

Warnings Regarding Use:

  • This approach might take a while to complete and calls for a reliable and powerful internet connection.

Method 2: Utilizing the Email Client Eudora

This approach uses Eudora, which is capable of handling files in the MBX file format, which is a subset of MBOX. Older versions of Outlook can use this strategy.

Phase 1: Paste Mailbox and Eudora Configuration

  • Set up Eudora using any email account after installing it.
  • Open Eudora’s default directory and copy your MBOX data file there.
  • Since ABCD.mbx and ABCD.mbox have a similar data structure, change the mail format.

Phase 2: Convert Outlook to Eudora Mailbox

  • When Microsoft Outlook is open, select the “File” tab to access the import and export wizard.
  • Then choose Eudora (2x, 3x, & 4x) lite & pro under “Import Internet Mail & Address”.
  • Choose your mailbox by browsing the Eudora mail location. If necessary, enable “Do not import duplicate email”.
  • After selecting the desired folder, click “Finish.”

Caution Before Using:

Note that only one mailbox can be exported at a time, so make sure you back up each mailbox before using this approach.

Method 3: Mailbox Export to EML File Format

Emails from MBOX are exported to the EML format using this procedure. EML files can be created with a variety of programs and email clients, including Mozilla Thunderbird, and then imported into Outlook.

An Alternate Approach:

Although these techniques provide free solutions to convert MBOX to PST, they can be laborious and require technical know-how. You can want to think about employing specialized software to streamline the procedure. A dependable method for transferring data from MBOX to Outlook PST format is Mailvita MBOX to PST Converter for Mac & Windows.
