Outlook by Microsoft stands as the most reliable email client compatible with both Windows and Mac OS platforms. It seamlessly adapts its user interface to match the respective operating system environment, along with utilizing distinct data file formats. Specifically, Windows employs PST (Personal Storage Table), while Mac OS employs OLM (Outlook for Mac). In cases where users transition from Apple products to Windows, a crucial step involves converting their data files from OLM Emails to Outlook PST, as Microsoft Outlook does not support OLM files. This article will provide a guide on importing Outlook for Mac OLM emails into Outlook versions 2019, 2016, and 2013.

If you’re in search of potential methods to import OLM files into the Windows Outlook environment, you’ve landed in the correct spot.

We’re all familiar with the fact that Microsoft Outlook stands as the premier email client globally, catering to both Windows and Mac OS users. Consequently, those who depend on OLM emails frequently find themselves in the position of needing to transfer their OLM data to Outlook.

In Microsoft Outlook versions 2019, 2016, and 2013, as well as Outlook 2016 for Mac, archiving mailbox items is a straightforward process. The mailbox information is stored in PST file format in Microsoft Outlook and OLM file format in Outlook for Mac. Additionally, it’s possible to import these OLM data files into various versions of MS Outlook.

Reason for importing Mac Outlook files to Windows Outlook
