Import MBOX to Office 365 with Ease – Complete Guide

Many email apps like Mozilla Thunderbird, Apple Mail, and Eudora use the MBOX file format to store emails. However, Office 365, which uses Microsoft Outlook and Exchange Online, does not directly support MBOX files. Moving emails from one platform to another is lengthy, especially when the file formats are different.

In this blog, we’ll explain how to import MBOX files into Office 365. We’ll cover both manual methods and automated solutions like the DRS MBOX File Converter to import MBOX to Office 365. So no matter your experience level, you’ll find a solution that works for you. Let’s get started and explore the best ways to bring your MBOX emails into Office 365 with ease!

Understanding MBOX and Office 365 Mailbox Formats

MBOX is a popular email file format used by several email clients to store messages. It organizes emails in a plain text format where all the messages are saved in a single file. Common email clients using the MBOX format include Mozilla Thunderbird, Apple Mail (Mac Mail), and Google Takeout.

On the other hand, Office 365 uses Microsoft Exchange Online, which supports PST and OST formats but does not natively support MBOX files. Hence, importing MBOX to Office 365 requires some intermediate steps.
