Thunderbird to Outlook Mac Migration is now free from all complications. Here is how you can do it.
Change is hard to accept. And this includes changing your email clients. When you switch over from Thunderbird to Outlook 365 (Mac & Windows), you are faced with few challenges, one of which is to get acclimatized with the new interface. While both clients offer an intuitive and efficient interface, getting comfortable with the “new” style can take time. But more serious than that is getting all your data migrated, which is not merely about acclimatization.
Thunderbird to Outlook Mac Migration
Thunderbird to Outlook Mac migration is a strange process, which can sometimes look straightforward from a distance but when you come down to doing it, many complications arise.
Challenges
The most obvious issue is the lack of compatible data files that can be shared with both clients. Unlike email clients like Apple Mail, Thunderbird, and more, that support data import through MBOX, Outlook Mac uses its own proprietary file format called OLM, or through Windows Outlook format called PST. If you try to feed it MBOX files, it won’t read anything back.
This stops a user right on the tracks. Thunderbird can archive emails to MBOX but the same file cannot be imported to Outlook Mac.
To go around this, a converter is needed. Lack of any official channel for migration from both Thunderbird and Outlook can be disappointing, leaving users to find their own means. And to rummage through the depths of internet only to find a converter that can convert the files as needed can take endless hours.
Even when a converter is eventually found, most traditional software is too weak and limited to actually prove to be effective in Thunderbird to Outlook Mac migration.
The Solution is here-
However, when USL Software released ‘Mail Extractor Pro‘, all the previous means of migration were abandoned for more powerful, safe, and proficient approach. This tool does not contain any of the outdated mode of processing and extraction that were responsible for issues like folder hierarchy loss, broken images, broken attachments, and so on.

‘Mail Extractor Pro‘ is an entirely new way of Thunderbird to Outlook Mac migration that leaves no chance for data error, time loss, or other complications.
The way it works is briefly explained below:
- You have two options to load the Thunderbird data you need to migrate:
- Either archive everything to MBOX and then convert MBOX files, Or
- Choose the ‘auto-load’ feature to let the software pick up the primary Thunderbird database automatically
- Once you have made your selection, you are free to select or de-select the folders inside the database.
- Finally, click ‘Start’ to start the process of data migration from your selected source into PST format.

‘Mail Extractor Pro’ converts Thunderbird to PST files, which has an added benefit of being able to use the same file with Windows version of Outlook, as well as Mac’s.
By following these three steps and finally importing the converted PST back to Outlook Mac, you would have successfully migrated everything. A task of dozens of convoluted steps and inputs is now possible in mere few clicks. You also find all your contents safely converted without any gaps in the integrity. The folder hierarchy, email attachments, images, and other parts of the database are picked up and processed by the tool safely.
