Advik OLM to ICS Converter is a standalone software tool for Windows and Mac that extracts and converts calendar data from Outlook for Mac (OLM) files into the universal ICS (iCalendar) format. The application supports both single and batch conversion, allowing users to process multiple OLM files or entire calendar folders at once. It preserves all calendar details, including events, subjects, start/end times, and metadata, while maintaining the original folder hierarchy. The software offers selective conversion with options to filter by date range or specific folders, and provides a preview of calendar items before export. It is compatible with all major OLM file versions, supports large files without size limitations, and features a user-friendly interface suitable for both technical and non-technical users. The tool is cross-platform, supports multiple languages, and generates detailed log reports after conversion. No Outlook installation or internet connection is required, and the converted ICS files can be imported into various calendar applications, including iCloud, Google Calendar, and others.
