Olm is a native and a proprietary file format used by Mac Outlook to store data. First introduced by Microsoft with Outlook 2011 for Mac, its a file that can store all kinds of data by Outlook as a client, such as emails, contacts, calendar, etc. However, it does not store any Outlook preferences or the account info.

This file is native to Mac Outlook and can’t be used anywhere else. There are no email clients in Mac or in Windows where you can import the file directly. Therefore, it’s not such a good news if you want to use Thunderbird, and looking to migrate your emails and other stuff to it. You can archive everything to a new Olm file but can’t import it anywhere else other than Outlook itself.

import olm to thunderbirdThe option left for you is to convert the file to a format that Thunderbird recognizes. However, this sort of file conversion doesn’t just happen by itself. It’s a complicated task and needs quiet some attention and proper sets of tools to get it right. Otherwise, the results could be data loss, corruption, and loss of your precious hours.

“Olm Extractor Pro” by USL Software is a program developed to ease this situation. It offers a direct conversion from Olm files to a Thunderbird database with everything preserved safely that you can upload to your Thunderbird client without noticing any difference. The process happens without any loss or modification of information or data element. You get every single part of data mirrored into your newly converted files that’s compatible with Thunderbird.

Here is a short, but important, list of the data and information types, that go amiss by any other tools, but not by “Olm Extractor Pro” –

  • S/MIME defined content
  • Email Attachments
  • Folder Hierarchy
  • Meta-data and Headers
  • Embedded Images and any other graphical objects
  • Nested Messages
  • Non-English and UTF-8 characters

All of these form a very important part of email database. And missing any thing among them can be a big source of pain. With “Olm extractor Pro”, you can be stress-free that that’s never going to happen.

Next thing that is really important to talk about is the interface for using the tool and its features. Since the task is very complicated, it depends a lot on the developers who develop the interface to ease the process and provide abstraction for managing complexity only at the back-end. “Olm Extractor Pro” does it surprisingly well.

When you launch it after installation, you will be presented with a very neat and clean interface with self-explanatory buttons. The instructions are such that even a complete novice would understand them. Much of the manual actions have been either eliminated or automated behind the screens, leaving only few things for an end-user to do – load Olm files, choose folders for conversion, choose output format (Thunderbird, in this case) and click ‘convert’ to start. That’s all. That’s the entire wizard that you need to go through for conversion, with the exception of few additional, but optional, features, such as given below –

  • save read/unread emails in separate folders
  • merge contacts to single Vcf file
  • merge calendar entries to a single Ics file
  • Filter types of items, such as mail, contacts, or calendar
  • ignore empty folders

Thus, making the dreaded job of importing Olm to Thunderbird a breeze.
