Free Ways to Move MBOX to PST – Windows and Mac

The importance of email management in the current digital world is self-evident, and email file conversion is usually in demand when changing email clients. One of the usual requirements is to convert MBOX files, which are common with email clients such as Thunderbird and Apple Mail, into PST format used by Microsoft Outlook. To that end, in the article below, we analyse free methods for such email file conversion on Windows and Mac.

Understanding the Basics: MBOX and PST

Before proceeding further with the methods, let me first explain what MBOX and PST formats are, respectively:

1. MBOX

A mailbox file format employed by several email clients where emails are stored in one long text file.

2. PST (Personal Storage Table)

A proprietary file format developed by Microsoft to keep copies of messages, calendar events, and much more within Outlook.

It becomes a requirement to migrate from MBOX to PST when users shift to Outlook due to its advanced features and professional appeal.
