Olminator is a conversion utility to convert "Microsoft Outlook for Mac" archives – so-called ".olm" files – into open file formats for emails (.mbox/.eml), calendar (.ics), contact information (.vcf/vCard, .csv) and notes (.html) – or even PDF or HTML.  This guarantees maximum interoperability and allows to smoothly import your data into Apple Mail, Apple Calendar, Apple Contacts, Apple Notes or other popular productivity applications.

The application has been specifically tuned to be interoperable with Apple Mail, Apple Calendar, Apple Contacts and Apple Notes applications.  

Arbitrary sized ".olm" archive files containing hundreds of thousands of emails, calendar events or contacts can be quickly converted "on the fly" due to the "streaming" approach of Olminator. No size restrictions apply so that even extremely large .olm archives (e.g. 100GB or above) can be converted reliably: hundreds of thousands of emails, thousands of calendar events and any number of contacts. As long as "Microsoft Outlook for Mac" can export your data into into an .olm archive, Olminator can convert it.  

Olminator gets the conversion job done fast: 
  - A 110GB .olm file containing 450.000 emails with 120.000 attachments gets converted in just 5 minutes on my MacBook Pro i7
  - Another 20GB .olm file takes 2 minutes on that same hardware
  - On the Apple M1 processor Olminator shows even smoother performance: that 20GB .olm file gets converted in just 1 minute

Olminator can of course handle internationalized content, e.g. Japanese or Chinese emails, or calendar events with start and end times in any timezone. 

Works with .olm archives exported from “Microsoft Outlook for Mac 2011” and “Microsoft Outlook for Mac 2016” / Office 365.

Everyone should be able to move their own data freely.
