Best Ways to Convert OLM to HTML (Secure Methods)

Common Reasons to Convert OLM File to HTML

• You switched from Mac to Windows and can’t open the OLM file anymore.
• You want to read old emails without installing Outlook again.
• HTML files open in any web browser, so it’s easier to access them anytime.
• You want to keep emails as a simple backup for record or legal purposes.
• HTML format keeps the email layout readable, which makes it good for archiving.

Manual Methods to Convert OLM to HTML Format

These only work if you still have access to Outlook for Mac and your emails are available there. They are fine for a small number of emails, but not practical for large OLM files.

Method 1: Direct Way to Export OLM Files to HTML

1. Open Outlook for Mac and go to the folder where your emails are stored.
2. Then, click on the email you want to convert.
3. After that, choose File > Save As.
4. Further, select Web Page (.html) or HTML.
5. At last, choose the location and click Save.

Method 2: Drag and Drop to Finder

1. Firstly, open Outlook for Mac.
2. Then, select one or multiple emails.
3. After that, drag them into a folder using Finder.
4. The emails will be saved as .eml files.
5. Right-click on any .eml file and choose Open With > Safari.
6. Once it opens in the browser, click Save As and select Web Page (.html).

Limitations

• You have to convert emails one by one.
• It only works if you still have access to Outlook for Mac. Without it, these steps won’t help.
• Attachments are not always saved properly with the HTML file. Sometimes they get stored separately.
• Folder structure is not maintained. Emails are saved individually, not in their original folders.
• There is a higher chance of missing some emails during manual selection.
• The drag-and-drop method creates .eml files first, which adds extra steps before getting the final HTML file.
• Large mailboxes can make the process slow and difficult to manage
