If you’re searching for the best OLM to MBOX converter, the most important factors to consider are data accuracy, speed, batch conversion, and ease of use. OLM files (Outlook for Mac) are not directly supported by many email clients, so converting them into MBOX format is essential for platforms like Thunderbird or Apple Mail.
From user discussions and software comparisons, professional converter tools are the most reliable option. Manual methods (like IMAP sync) are time-consuming and may risk data loss, especially for large mailboxes.
One of the best solutions is ATS OLM to MBOX Converter, which offers:
- Bulk conversion of multiple OLM files
- Complete data transfer (emails, attachments, contacts, calendars)
- Preservation of folder hierarchy and metadata
- No need for Outlook installation
- Fast and secure offline conversion
Other tools like SysTools or BitRecover also perform well, offering features like preview, filters, and batch processing
