Export Thunderbird Emails to Outlook PST (Windows, Mac, and Linux Versions)

Both Thunderbird and Outlook client doesn’t provide any direct means to export or import their mailbox data to each other email platforms. Therefore, in order to migrate emails from Thunderbird to Outlook, you have to convert Thunderbird’s MBOX to PST file format.

Note: The default file format supported by Outlook for Windows and Mac machines is PST and OLM, respectively.

Suppose you are using Thunderbird and Outlook both on a Mac system, and you want to migrate Thunderbird emails to Outlook for Mac. What are the steps you need to follow in order to do that?

Well, Thunderbird doesn’t provide any inbuilt feature to export its email messages to Outlook for Mac. Therefore, in order to achieve migration on a Mac platform, first, you need to convert Thunderbird emails to OLM file format.

OLM is the default file format used by Outlook for Mac users. OLM files cannot be accessed directly by Outlook on the Windows environment. Once Thunderbird emails are exported to an OLM file, it can be easily imported via Outlook for a Mac. However, to access the same mailbox data on Windows Outlook, you have to convert OLM to PST.

The first step requires locating the required email messages via the Thunderbird client manually. Once located, Ctrl + select the required emails, right-click and select Save As >> EML files.

The second step enables you to import the converted EML files to Windows Live Mail’s mailbox. You can simply drag-and-drop the required EML files to the desired mailbox folder.

At last, use the Export emails functionality provided by Windows Live Mail to export all the required EML files to MS Outlook.

Thunderbird to Outlook Migration on Linux

Like Thunderbird, Linux is also an open-source platform with support for multiple email client applications. However, Thunderbird is the most preferred email client for Linux-based users.

Thunderbird stores its data in MBOX format, whether you are using it on Windows, Mac, or Linux. Therefore, to migrate Thunderbird emails (Linux) to Outlook (Windows), first, you have to locate Thunderbird mailbox data on Linux. Typically, Thunderbird data is saved at the following location on your Linux machine.

/home/username/.thunderbird

Once you got the source location of Thunderbird mailbox data, all you have to do is: Go to the Home directory, press Ctrl + H to unhide hidden files, copy the entire directory and paste it on an external storage device. The data on the external hard drive is then moved to the Windows platform and convert to PST.
