How to Export PST to MBOX Format?

If you switch from Microsoft Outlook to another email client such as Thunderbird or Apple Mail, we recommend exporting the PST file to a format compatible with these email clients. One such format is MBOX, used by popular email clients such as Thunderbird, Apple Mail, and Eudora. This article explains how to export PST to MBOX file format.

PST and MBOX are two file formats used to store email data. PST is a proprietary file format used by Microsoft Outlook and MBOX is an open source file format used by multiple email clients such as Mozilla Thunderbird.

One of the major differences between PST and MBOX is compatibility with various email clients. PST files can only be used with Microsoft Outlook, while MBOX files can be used with several email applications. This makes MBOX a more versatile file format and allows users to switch between email clients more easily.

Another difference is the file size limit. The maximum PST file size is limited to 2 GB in older versions of Outlook and 50 GB in newer versions. In contrast, MBOX files have no size limit, making them ideal for storing large amounts of email data.

Finally, PST and MBOX file structures are also different. PST files store email data in a hierarchical structure containing folders and subfolders. MBOX files, on the other hand, store email data in a single file that contains all email messages.

In summary, PST is a proprietary file format compatible only with Microsoft Outlook, while MBOX is an open source file format compatible with multiple email clients. Additionally, MBOX has no file size limit and stores email data in a single file, making it a more versatile and flexible file format.
