If you need to extract some emails for use in another application, EML is a viable alternative to OLM. The OLM is an Outlook archive and EML is an email message, so it is natural that some would want to know how to Convert OLM file to EML without having to go through the entire migration process.

We will explore the OLM and EML difference and show you both a manual and automated way of going about it.

Why Convert OLM File to EML?

OLM files are typically associated with Outlook for Mac application. EML files can be associated with Thunderbird or Apple Mail.

You might want to Convert OLM file to EML when you need to:

  • Access individual emails outside of Outlook for Mac

  • Share the emails as individuals

  • Export them to EML-compatible application

  • Save them as a transportable file

  • Extract them from the OLM archive

OLM Vs EML: What Is the Difference?

The difference between the two file types lies in the contents they hold. OLM is an archive of your mailbox while an EML file holds individual messages.

OLM files are intended to hold everything associated with our mailbox in one place (Outlook for Mac mailbox). EML files are singular with just the messages and their attributes.

How to Convert OLM File to EML

There are two possible ways: a manual approach and using a tool.

Method 1: Manually Convert OLM to EML

This particular method is only good for single messages rather than a bulk.

In older Outlook for Mac versions, the method would be to drag the message onto the desktop. For users who do not have a modern Outlook version, the method is somewhat tedious.

The instructions are as follows:

  1. Open Outlook for Mac with the OLM data
  2. Navigate to the folder with the necessary message
  3. Select the message and drag-drop it on the desktop
  4. The message will be saved as an EML file
  5. You can proceed with the next message

It is a simple process but a lengthy one if you need to do it for a few hundred or thousand messages.

Method 2: Convert OLM File to EML Using SysTools OLM Converter

SysTools OLM Converter is a tool that allows you to bulk convert OLM files to EML. The steps are as follows:

Step 1: Download and Install the OLM Converter

Download SysTools OLM Converter, and install it on your Windows machine.

Step 2: Add the OLM File

Launch the application and use the Add File or Add Folder option (see image below) to select the OLM file you wish to convert.

Step 3: Preview the OLM Data

After selecting the file, the application will preview its contents in the left-hand side panel.

Step 4: Start the Conversion

Click Export> select EML as the output format> select the folder where you want the converted files saved, and click Export. These four steps were taken directly from the SysTools documentation on how the OLM Converter works in Windows 10.

Why Use SysTools OLM Converter

SysTools OLM Converter is a great tool in situations where the manual approach is too time-consuming. The tool allows bulk conversion with the Add Folder feature and the ability to preview the mailbox data. Moreover, the OLM to EML conversion tool allows filtering by date and selective message export (choose which items to export). Plus, the application converts message attachments as well.

The tool provides multiple output options (EML is only one of them) and maintains the folder structure and metadata of the emails.

Conclusion

While the manual approach is viable for a few messages the tool makes more sense when dealing with a larger mailbox. With the tool, you can select the OLM file or folder, preview the data, choose what you need and convert OLM file to EML right in Windows.
