SetuFlow OLM Converter
Your Mac Outlook archive, readable on Windows
Outlook for Mac exports to .olm — a file Windows Outlook cannot open. SetuFlow OLM Converter opens it on any Windows PC and turns your mail, contacts and calendars into the formats Windows and every other mail client understand.

Contacts and calendars too
Export Mac Outlook contacts to vCard or CSV and calendars to ICS, so they import cleanly into Windows Outlook, Google or a phone.
Precise filters
Filter by date, sender, recipient, attachments and type, size and read state, with presets and a live count.
Fast on big archives
A 35 GB archive indexes in about 9 seconds; 250,000 emails convert to MBOX in under two minutes on a modern PC.
Queue, resume, history
Run several archives in a queue, cancel and resume without duplicates, and keep a history with HTML, CSV and JSON reports.
Read-only
The OLM archive is opened read-only and is never changed, so you can always go back to the original.

OLM Converter, answered
What people want to know before they buy. Anything else — the assistant or a human will answer it.
Windows Outlook cannot open OLM files. Install SetuFlow OLM Converter, add the .olm file, and you can read it immediately in the free viewer or convert it to MBOX, EML, MSG, PDF and other formats.
Archives exported from Outlook 2016 for Mac and later. Older Outlook 2011 archives and password-protected archives are not supported.
PST output is not offered yet; it will appear on this page when it has passed validation. Today you can move OLM mail to Windows through MSG files, or to other mail clients through MBOX and EML.
Yes. Contacts export to vCard and CSV, and calendar events to ICS, alongside the mail.
The Free edition is free forever, with a limit of 25 items per conversion job. Professional removes the limit. Your licence key is checked offline on your own PC, so the converter keeps working without an internet connection and nothing about your mail is ever sent to us.
No. The converter is desktop software: it reads the file on your disk and writes the result to a folder you choose. Your source file is opened read-only and never changed. The only time data leaves the PC is if you choose to upload to your own mail server in the Business edition.
