Many businesses and professionals use Mac Outlook to manage their emails, contacts, calendars, and other mailbox data. The OLM file format is used to store all of the mailbox data in Mac Outlook. This format works well in Mac Outlook, but it can be a problem when users try to export Mac Outlook Files to MBOX-supported email clients. The MBOX file format is supported by many well-known email programs, such as Mozilla Thunderbird, Apple Mail, and others. OLM is not.

Because of this, users often have to perform OLM mail to MBOX conversion. In this guide, we'll talk about why you might want to do this conversion, some common problems that come up, and the easiest way to change a Mac Outlook Mailbox to MBOX.

What OLM and MBOX File Formats Mean

It's important to know the difference between these two file types before you start converting them.

Format for OLM files

The Outlook for Mac data file is what OLM stands for. Microsoft Outlook for Mac uses this file format to store emails, contacts, calendars, tasks, notes, and attachments in the mailbox. In Mac Outlook, OLM files are mostly used for backing up data and exporting it.

The MBOX File Format

Many email programs support MBOX, which is a common format for storing email. Some well-known email programs that work with MBOX are:

  • Thunderbird from Mozilla
  • Mail from Apple
  • Eudora and Opera Mail
  • Entourage Spicebird

MBOX files keep email messages in a single text file, with each message saved one after the other.

Users need to change OLM files into MBOX format in order to read their emails in these email clients because Mac Outlook does not support MBOX directly.

Why You Should Change Mac Outlook Mailboxes to MBOX

Users may need to export Mac Outlook files to email clients that support MBOX in a number of situations.

1. Changing Email Services

A lot of people who use Mac Outlook switch to other email programs, such as Thunderbird or Apple Mail. You have to change OLM files because these clients use the MBOX format.

2. Better email management

Some people like using other email clients because they have different features or make it easier to manage their email.

3. Backing up data and making it easy to get to

Many email programs support the MBOX format, which makes it easier to access. Changing OLM files to MBOX makes sure that email data can be accessed for a long time.

4. Moving to email clients that are open source

People who want to switch from Microsoft Outlook to open-source email services often change OLM files to MBOX files.

Manual Steps to Convert Mac Outlook OLM to MBOX

Step 2: Open Apple Mail and click File > Import Mailboxes.

Choose Outlook for Mac archive (.olm) and import the OLM file.

Step 3: Install Mozilla Thunderbird on your system.
