SysInfo Mac OLM Converter offers a dedicated OLM to PST conversion feature that addresses a common challenge faced by users switching from Mac Outlook to Windows Outlook. Since Mac Outlook stores data in OLM format while Windows Outlook relies on PST, moving between the two platforms without a proper tool can be quite frustrating. The software handles this by converting OLM mailbox data — including emails, contacts, calendars, tasks, and notes — into a PST file that Outlook for Windows can readily open. A notably useful addition is the Split PST feature, which allows users to break the resulting PST file into smaller chunks, reducing the risk of file corruption that often comes with oversized PST files. The tool also preserves the original folder hierarchy during conversion, so users don’t have to reorganize their mailbox afterward. While the free version restricts output to 50 emails per folder, the full version removes that limitation and handles files of any size without restrictions.
