Keep reading for a detailed, step-by-step guide on how to move your MBOX data to Outlook no matter which version or operating system you’re using.

Overview of MBOX & Outlook 365

MBOX is one of the most widely used file formats for storing email messages. It is supported by various email clients such as Eudora, Thunderbird, Apple Mail, and even allows Gmail messages to be exported in this format. Due to its flexibility and open standard, MBOX is a common format for users handling mailbox data across different platforms.

However, not all email clients support the MBOX format Microsoft Outlook being one of them. This creates a challenge when users want to switch from an MBOX-based email client to Outlook 365.

Outlook 365, also known as Outlook Web App (OWA), is part of the Office 365 subscription suite and is widely adopted by enterprises and professional users. Despite its robust features and integrations, Outlook does not natively support MBOX files. Instead, it works primarily with PST (Personal Storage Table) files for importing and exporting email data.

So, if you’re looking to import MBOX files into Outlook 365 particularly on Mac the first step is to convert MBOX file to PST format. Once converted, the PST file can then be easily imported into any version of Microsoft Outlook, including Outlook 365, 2021, 2016, 2013, and even 2010.

Now, let’s take a closer look at the key reasons why users often need to migrate MBOX files to Outlook 365 on Mac OS.

Method 1: Manually Migrate MBOX to Outlook 365 via Thunderbird

One of the most commonly used manual methods to transfer MBOX files to Outlook 365 involves the use of both Mozilla Thunderbird and Microsoft Outlook. This process allows you to indirectly convert MBOX file to PST by exporting messages through Thunderbird.

Step-by-Step Instructions:

1. Launch Thunderbird on your system.
2. Import or open the MBOX file within Thunderbird (you may use an add-on like “ImportExportTools NG” if needed).
3. Select the emails you want to migrate, then right-click and choose “Save As”.
4. Save the selected messages to a dedicated folder on your system.
5. Now, open Microsoft Outlook.
6. Navigate to the desired mailbox or create a new folder in Outlook.
7. Drag and drop the saved email files from your folder into the Outlook folder.

Once imported into Outlook, the messages are stored in PST format, making them accessible and manageable within the Outlook environment.

Limitations of This Method:

• Batch import is limited: You can only move a limited number of emails at a time, which is inefficient for large mailboxes.
• Software dependency: You must install both Thunderbird and Outlook on the same machine.
• Technical complexity: The process can be confusing for non-technical users, as it involves several manual steps and temporary file handling.

Expert Tip: Due to its complexity and limitations, this method is best suited for small-scale migrations. If you’re dealing with large or multiple MBOX files, or if you’re not comfortable with technical procedures, consider moving to Method 2 — a more reliable and user-friendly approach to import MBOX into Outlook 365 with full email attributes intact.
