User-Query:
In my old MacBook, I have many client details that are stored in OLM files. But now these days I am using Zoho Mail. So, is it possible to save my file in Zoho from OLM?

Summary: If you’ve used Outlook on a Mac, you know it saves emails in OLM files. The problem is, Windows and other platforms can’t read them easily. That’s why many people choose Zoho Mail instead. It works in any browser, keeps your emails online, and doesn’t lock you to one device. In this blog, I’ll show a manual way to import OLM to Zoho Mail and also an easier option using the MacSonik OLM Converter Tool.

  • Zoho Mail works in your browser. You can check your emails anywhere.
  • Keeping emails online is easier than managing files on one system.
  • You’re no longer tied to a Mac to access your old emails.
  • Everything stays in one account, ready to access anytime.
