OLMExport offers a browser-based way to read an Outlook for Mac archive or convert it into formats including MBOX, EML, PDF, searchable HTML, CSV, contacts, and calendar files.

Landing page captured for the 2026-09-24 issue.

For: Outlook for Mac archive owners
Worth noticing: The page reports testing a 1.7 GB archive of 50,000 messages and advises converting folder by folder for very large files in Safari or Firefox.

Field notes

The workflow reads the archive entry by entry in the browser and hands the locally assembled output to the browser’s download mechanism; the page says no server handles conversion. It offers a viewer as well as exports, with large-file guidance that distinguishes Chrome and Edge disk writing from Safari and Firefox memory use. The site reports testing a 1.7 GB archive containing 50,000 messages; that result is self-reported.
