The migration from a Windows-based computer to Mac is a wonderful experience. Yet, switching from one operating system to another brings about some challenges while migrating the entire data stored in both systems. One of the biggest obstacles that people usually encounter while making such a change is importing email history; in particular, moving data from Microsoft Outlook.

Microsoft Outlook stores all emails, calendar entries, contacts, and tasks in a PST file on Windows. However, Mac computers use other formats to store their emails, such as OLM format for Outlook for Mac or MBOX format for Apple Mail. Therefore, because a Mac computer and its native programs cannot open a PST file directly, you need to migrate this data using certain strategies.

In this step-by-step guide, we will discuss how to efficiently transfer Windows Outlook PST files to a Mac.

  • Deep folders may lose their structure and become unorganized with your emails all messed up.
  • Foreign letters, pictures, as well as email metadata like “To”, “CC”, “BCC” headers are likely to be lost during cross-platform conversion.
