Summary: Email data is stored in different formats depending on the email client. Applications like Mozilla Thunderbird, Apple Mail, and Eudora usually save mailboxes in the MBOX format. But Microsoft Outlook for Mac uses a different file type called OLM to store emails, contacts, and other data. Because of this, users often need to convert MBOX files before moving to Outlook for Mac. The problem is that MS Outlook cannot import MBOX files. In this guide, we’ll look at manual and professional use of MCD MBOX Migrator to convert MBOX to OLM safely.
People decide to convert MBOX files to OLM for different reasons. Most of the time, it happens when they switch their email app. Some of the common reasons are given below:
There isn’t a direct way to convert MBOX files to OLM. Microsoft Outlook for Mac simply doesn’t support importing MBOX files. Because of that, users usually rely on a small workaround.

The manual way can get the job done. But it’s not always smooth. There are a few issues to export MBOX files to OLM.
MBOX Migrator is a tool people use when they need to convert MBOX files. It can change MBOX data into different formats like PST, EML, or EMLX. It also lets users move emails to services such as Gmail or Office 365. You can add one file or many MBOX files at the same time.

Benefits of using a professional approach:
