How to Open Mac Outlook Mailbox in MBOX Apple Mail

Microsoft Outlook is the email, contacts, calendar, and attachment manager that many Mac users use. The OLM file format is what Outlook for Mac uses to store mailbox data. This format is mostly used for exporting or backing up Outlook data. However, users often have trouble getting their Outlook emails into Apple Mail because Apple Mail only supports the MBOX file format, not the OLM file format.

Because of this difference, a lot of users look for a safe way to change Mac Outlook Mailbox to MBOX format so users can open their emails in Apple Mail without losing any important information.

This guide will show you how to open a Mac Outlook file to MBOX Apple Mail and safely read your Outlook emails.

Why Users Need to Change Mac Outlook Mailbox to MBOX

There are times when users need to change a Mac Outlook mailbox to MBOX format. Some of the most common reasons are:

• Moving from Outlook for Mac to Apple Mail
• Getting to Outlook emails in Apple Mail
• Making a backup format that works with other formats
• Moving email data to a different email client
• To avoid problems with compatibility between different email platforms

It's required to convert the Mac Outlook Mailbox to MBOX format so that Apple Mail can open it easily.

What is the MBOX format and the Mac Outlook Mailbox?

It is important to know these two file types before you start the process.

Mailbox for Mac Outlook (OLM)

When you export mailbox data from Mac Outlook, it saves it in an OLM file. This file has:

• Attachments to emails
• Users
• Entries in the calendar
• Things to do and notes

Outlook for Mac is the only email program that can open OLM files, which makes it hard to open them in other email programs.

Format of MBOX File

Many email clients, including the following, support MBOX, which is a common email storage format:

• Mail from Apple
• Thunderbird
• Eudora
• Group of Users

This is why Users often change their Mac Outlook Mailbox to MBOX format so they can read their emails on more than one platform.
