If you’re planning to switch systems, you may be wondering how to open OLM Files on Mac and Windows. Since OLM files are not supported outside Mac Outlook, manual steps often take too long and risk data loss. That’s why many users prefer MailConverterTools OLM Converter Software. It allows you to convert OLM files into multiple formats like PST, MBOX, and EML, and even migrate them directly to cloud platforms like Gmail or Office 365, all while preserving data integrity. The software is embedded with a Date Range Filter option that helps users to export data based on the date range(Start Date and End Date) and categories like Email, Contacts, Calendar, Notes, etc. Furthermore, the software offers a Remove Duplicate Emails feature that helps to remove duplicate emails and lets you choose a specific date range to convert only the emails you need.
