Working Steps - How to Get MBOX File in Outlook 365

Email communication is at the heart of both personal and professional activities. Over the years, different email applications have adopted different file formats to store email data. One of the most widely used formats is MBOX, supported by email clients like Apple Mail, Thunderbird, Eudora, Entourage, and more. However, many individuals and businesses today prefer to use Outlook 365 (Microsoft 365 Outlook) because of its enterprise-grade features, cloud accessibility, and seamless integration with the Microsoft ecosystem.

The challenge arises when users need to import or open MBOX files in Outlook 365, as Microsoft’s email client does not natively support the MBOX format. This blog will guide you through the essentials of MBOX files and Outlook 365, explain why users migrate, explore manual methods, highlight the drawbacks of such methods, and introduce a reliable alternative for a smooth transition.

Overview of MBOX Files & Outlook 365

MBOX is a mailbox storage format used by many open-source and desktop-based email applications. It stores an entire folder of emails in a single text-based file. Each email is saved sequentially, making the file easy to handle for clients like Thunderbird or Apple Mail. However, MBOX is not compatible with Microsoft Outlook 365, which instead uses PST or OST file formats for managing mailbox data.

Outlook 365 is part of Microsoft’s cloud-powered Microsoft 365 suite. It provides email, calendar, contacts, and productivity features that are accessible from anywhere, on any device. Outlook 365 is preferred by businesses due to its integration with Teams, OneDrive, and other Microsoft apps, offering a centralized, secure, and scalable communication platform.

Reasons to Get MBOX Files into Outlook 365

There are several reasons why users need to import MBOX files into Outlook 365 -

• Switching Platforms – Migrating from Thunderbird, Apple Mail, or other MBOX-based clients to Microsoft Outlook.
• Centralized Access – Accessing all emails in Outlook 365 without switching between different applications.
• Cloud Backup – Outlook 365 provides cloud-based storage, reducing the risk of local data loss.
• Business Continuity – Companies moving to Microsoft 365 often migrate historical emails stored in MBOX files.
• Stronger Protection – Microsoft 365 delivers superior security and compliance tools not available in traditional MBOX email clients.

Manual Approach for how to Get MBOX Files in Outlook 365

Since Outlook 365 does not directly support MBOX, the manual method involves a multi-step workaround using Apple Mail, Thunderbird, and Outlook -

• Open MBOX File in Apple Mail
• Import the MBOX file into Apple Mail.
• Confirm that all emails are visible.

Export Emails from Apple Mail

• Choose the export function to store the messages in EML file format.

Import EML Files into Thunderbird

Drawbacks of the Manual Method

While the manual approach may work, it comes with several significant drawbacks -

• Complicated & Lengthy – The process requires multiple applications (Apple Mail, Thunderbird, and Outlook), making it time-consuming.
• Data Loss Risks – Attachments, metadata, and formatting may not always transfer properly.
• No Batch Processing – Handling multiple or very large MBOX files is impractical.
• Technical Expertise Required – Non-technical users may find the steps confusing and prone to errors.
