Microsoft Outlook grows more and more popular every day. It is now among the most widely used email clients worldwide. The main factors contributing to its appeal are its exceptional services and a few superior features. However, some of us are unable to utilize Outlook because we are utilizing various email clients.
Those who use Mozilla Thunderbird and Apple Mail to view their mail are typical instances. These are the two primary email applications that store emails in the MBOX format. Less-known clients that support MBOX files include Mulberry, Entourage, Eudora, and others.
The complete email folder in a single database file is included in an MBOX file, which is a chain of emails. We must first convert MBOX files into other file formats before we can open them in Outlook. The detailed process is described here. Let’s first talk about the necessity of importing MBOX files into Outlook.
Why?? Converting MBOX files to PST files is Required

Typically, Outlook for Windows imports data into PST and OLM file formats. Compared to the MBOX format, this PST format offers several benefits. Outlook is preferred by users of email clients that use MBOX files for the reasons listed below.
- The spam emails were not filtered by Thunderbird. However, Outlook has an anti-spam feature that shields data from unsolicited emails.
- Outlook uses password security to encrypt emails and other email correspondence.
- Additionally, it has an integrated calendar function that aids in keeping track of crucial activities. In Thunderbird mail, we must add a third-party addon.
- The Microsoft Exchange server, which keeps all email correspondence offline, is compatible with Outlook.
- Outlook has some benefits over email clients that support MBOX. The need to export Thunderbird emails to Outlook is also prompted by it.
Let’s address the primary issue of how to access MBOX files in Outlook right away.
