Summary: Switching between platforms like Mac Outlook and Windows Outlook can be hectic when your email data is stored in different file formats. Outlook for Mac doesn’t directly support exporting to MSG, and Windows Outlook can’t read OLM files. So, to open your emails on your Windows PC, you’ll need to transfer OLM Data to MSG Format. In this blog, we’ll show you two reliable ways to perform this: The manual method and a professional DRS Softech OLM Converter Tool. Additionally, each method offers you a quick and hassle-free conversion.
Understand: OLM and MSG File Format
An OLM file is used by Outlook on Mac to store emails, contacts, and calendars in a single archive. In contrast, an MSG file is a Windows Outlook format that saves individual email messages with all their data. Also, OLM isn’t supported on Windows, so conversion is needed for cross-platform access.
Simple Steps to Convert OLM File to MSG
- Firstly, download and install the DRS Softech OLM Converter Tool.
- Choose: Select Files or Select Folder to add an OLM file. Click Next.
- Then, pick MSG as the Saving Format from the drop-down list.
- Lastly, apply several features and filters. Click Start Process.
Why Convert OLM to MSG?
- MSG files are supported by Windows Outlook for viewing individual emails.
- It’s easier to organize or share specific emails in MSG format.
- Also, MSG files preserve all properties of the original message, including attachments, subject line, timestamps, and metadata.
Does Windows Outlook Support OLM Files?
No, Windows Outlook does not support OLM files. OLM is a proprietary format used only by Outlook for Mac. If you’re switching to Windows or trying to access OLM data in Outlook on a PC, you must export OLM File into MSG.
Manual Method to Convert OLM File to MSG
Unfortunately, there is no direct manual method to convert your OLM to MSG. However, you can use this with multiple steps:
Step 01: Export OLM File from Mac Outlook:

- Now, save the OLM file to your system.
Step 02: Import OLM into Outlook for Windows (via IMAP):
- Next, create a new IMAP email account (like Gmail).
- Sync your Mac Outlook with this IMAP account.
- After that, move all emails from your OLM mailbox to the IMAP folders.
- On Windows Outlook, add the same IMAP account.
- Once emails appear, drag and drop them into a local folder.
Step 03: Save Emails as MSG Files:
- Further, open the emails in Outlook on Windows.
- Afterwards, click File > Save As.
- In the end, choose .msg as the format and save.
