It's common for users to move their email when they switch platforms, change email clients, or need a backup format that is more flexible. You need a safe way to convert Outlook for Mac to MBOX that keeps your email data safe. Users often look for a good way to convert OLM to MBOX because Outlook for Mac stores mailbox data in OLM format. This guide explains both ways to export OLM to MBOX, whether you want to do it yourself or use a professional tool.

Why Convert Outlook for Mac to MBOX Format?

It's important to know why the conversion is happening before we go over the steps.

The main program that can open OLM files is Outlook for Mac. Many programs, such as Mozilla Thunderbird, Apple Mail, and a number of Linux-based email clients, do support MBOX, though.

Switching to MBOX helps with:

• Switching email services
• Making copies of emails that can be moved
• Not depending on software
• Switching to systems that are open source
• Accessing data on more than one system

If you need something that can do a lot of things and is flexible, MBOX is a good choice.

How to Make Sense of OLM and MBOX Formats

OLM Format:

• The short form of OLM is "Outlook for Mac Data File."
• Holds on to emails, contacts, calendars, notes, and files.
• Created by Outlook for Mac
• Not very compatible with other programs

Mailbox File Format (MBOX):

• Keeps all emails in one text file
• Works well on many different platforms
• Used a lot to move and store information
• You can't directly "Export to MBOX" in Outlook for Mac, so you'll have to find other ways to do it.

How to Convert Outlook for Mac to MBOX Manually

You sync emails through an IMAP account and then export them using an email client that supports MBOX when you do it by hand.

Step 1: Get information out of Outlook for Mac. Start Outlook for Mac.

• From the File menu, choose Export.
• Pick things from your mailbox, like Mail, Contacts, and so on.
• Turn the data into an OLM file.
• This step makes a backup of the data in your mailbox.

Step 2: Set up an email account with IMAP

To move emails:

• Set up an IMAP email account in Outlook for Mac.
• Start Mozilla Thunderbird and log in to the same account.
• You can move emails from Outlook to the IMAP folders by dragging and dropping them.
• Let it sync for a while.

This sends your emails to the server for mail.

Step 3: Use Thunderbird to send your emails to MBOX.

• Install Thunderbird on your computer.
• Install the ImportExportTools NG add-on.
• Right-click on the folder that is synchronized.
• Choose the MBOX format from the menu for the Export Folder.
• Place the exported file where you want it to go.

The MBOX format is now used for your Outlook emails.

Drawbacks of the Manual Method

The manual method is free, but it has some issues:

• It takes a long time with big mailboxes.
• Needs to be set up technically
• It's possible that synchronization won't be done.
• It is possible that the folder structure will change.
• Sending attachments sometimes has problems, but not very often.
• You need the internet to sync IMAP.

If your mailbox is small and not very important, this method might work well. But the risks are much higher when it comes to data for businesses or professionals.

Now think about this: Is it worth putting your data at risk to save money?
