Convert Outlook OLM File to MSG File Format – Easy Guide

If you try to open your Outlook emails from a Mac on a Windows computer, you may run into problems. It happens because Mac Outlook saves emails in OLM format, while Windows Outlook uses MSG format to store messages. So, when someone moves from a Mac to a Windows PC or wants to view their emails in Outlook for Windows, converting OLM to MSG becomes important. With the help of the reliable OLM Converter Tool, you can convert OLM files to MSG in a hassle-free way. In this guide, we’ll show you two easy ways to convert your emails – one using a tool and the other manually. This way, you can pick the method that works best for you.

Top Reasons to Export OLM to MSG File Format

Here are some clear and simple reasons why you might want to export your OLM emails to MSG:

• OLM files work only in Mac Outlook, while MSG files work in Windows Outlook.
• MSG format saves one email per file. Hence, it is easy to find, store, or send just one message.
• You can share MSG files quickly by attaching them to an email or saving them to a folder.
• If you’re moving from Mac to Windows, converting OLM to MSG helps retain access to your emails.
• Instead of converting the whole file, you can export only the emails that are important to you.
• The MSG format is easier to store or archive as individual emails for legal or backup purposes.

Understanding these reasons makes it clear why the OLM to MSG conversion is useful. Now, let’s see how you can do it step by step.

How to Convert OLM Files to MSG

There are two main ways to convert OLM files to MSG format. First one is quick and automatic using a professional tool. And the other is a manual method that takes more time and effort. Let’s take a look at both methods to simplify the conversion process: 

Method 01: Manual Method to Convert Mac Outlook OLM to MSG

This process involves using an IMAP-enabled email account (like Gmail) to move your Mac Outlook emails to a Windows system. Once the emails are available in Windows Outlook, you can save them as MSG files.

• First, open Outlook on your Mac and go to Preferences > Accounts.
• Next, add your Gmail account using IMAP settings (not POP).
• Once added, wait for Outlook to sync with the Gmail account.
• Now, drag and drop the emails or folders you want to convert into the Gmail folder.
• After that, allow some time for all the emails to sync with Gmail properly.
• Then, switch to your Windows computer and open Outlook.
• Add the same Gmail account that you used on your Mac.
• Let Outlook finish syncing the emails from Gmail to your Windows Outlook.
• Now, open any synced email inside Outlook on Windows.
• Click on File > Save As from the top menu.
• Choose MSG as the file format, pick a folder to save the email, and click Save.
• Repeat this last step for each email you want to export as MSG.

This method helps you convert OLM to MSG for free. But it’s best suited for converting a few emails. If you have a large number of emails, this process can become slow and complex. 

Limitations Associated With the Manual Method

While the manual method can work for a few emails, it comes with several drawbacks. Here’s why it may not be the best choice for everyone:

• You have to save each email one by one, which is very slow if you have hundreds or thousands of emails.
• You must switch between two devices, making the process more complicated.
• Outlook doesn’t allow you to save multiple emails as MSG files at once.
• Some attachments or formatting can be lost during the move.
• If syncing fails or you forget to move certain folders, some emails may not get converted.
•  Setting up IMAP, syncing, and exporting can be confusing for non-technical users.

Because of these limitations, many users prefer using a professional tool that saves time and ensures accuracy.
