What is the best way to import OLM files into iCloud Mail?

The best way to import OLM files into iCloud Mail is by using a professional OLM conversion and migration tool, as iCloud Mail does not support OLM files directly. Aryson OLM file Converter offers a secure and efficient solution for this task. The software allows users to open and preview Mac Outlook OLM files and then migrate emails to iCloud Mail through IMAP authentication. It ensures complete preservation of folder hierarchy, email metadata, and attachments during the migration process. Aryson OLM Converter also supports bulk migration, selective data transfer using date filters, and duplicate removal to maintain mailbox accuracy. With its standalone architecture and user-friendly interface, the tool enables seamless OLM to iCloud Mail migration without requiring Outlook installation, ensuring data integrity and zero data loss.
