The MBOX file format is widely used by many leading email clients, including Mozilla Thunderbird, Apple Mail, and Opera Mail, to store email data. However, when it comes to Microsoft Outlook, the MBOX format is not supported natively. If you’re looking for a way to view MBOX files in Windows Outlook, this guide will walk you through the two primary methods: a manual way and an automated way using third-party software.
Let’s dive into these methods and explore the best options available for you.
What is MBOX and Why Doesn’t Outlook Support It?
Before we dive into the methods, let’s briefly review the technical aspects.
- MBOX (Mailbox Format) is a file format that stores email messages, typically used by several open-source email clients like Thunderbird and Apple Mail. MBOX files store all messages of a mailbox in a single text file, making it easy to manage and transfer email data across different platforms.
- PST (Personal Storage Table) is the format that Microsoft Outlook uses to store emails, contacts, calendar entries, and other data. Outlook does not directly support the MBOX format, which is why you need to convert or import MBOX data using other methods.
If you are an IT professional managing email migration for your organization, you might need to consider these methods for seamless transfer from MBOX-based email clients to Outlook.
Ways to View MBOX Files
There are two ways to view MBOX file in Windows Outlook.
1. Manual Way
You need to first import the MBOX file into an MBOX-based application, such as Mozilla Thunderbird and then create a dummy Gmail account to transfer the MBOX data to Windows Outlook. Follow these steps:
- Install Mozilla Thunderbird on your system and create a new account.
- After the account is set up, right-click Local Folders.
- In the menu that opens, click Settings.
- In the window that opens, click the Browse button and provide the location of the MBOX file’s folder.
- Restart Thunderbird. The folders saved in the MBOX file will be displayed under the Local Folders tab.
- Create a dummy Gmail account and then setup the account in Thunderbird.
- Drag and drop the MBOX emails from the Local Folders tab to a folder in the Gmail mailbox.
- After copying all the emails from MBOX to Gmail, close Thunderbird.
- Open Microsoft Outlook on your system and set up the same Gmail account you used earlier. Wait for the application to download your emails from Google’s server.
