If you are an email admin or IT professional dealing with Mac Outlook data, you've likely encountered OLM files. These files are proprietary to Mac Outlook and can't be opened in other email clients like Apple Mail, Thunderbird, or Eudora, which rely on the MBOX format. The only way to bridge this gap is to convert OLM to MBOX.
In this blog, we'll explore how to perform this conversion safely and efficiently using the MyDigiSoft OLM Converter Tool—a professional-grade utility designed for seamless data migration. Whether you're planning a mail client switch, need to archive Mac Outlook data, or simply want better compatibility, this guide is for you.
