We’re learning how to transfer your data from the Thunderbird email client to Outlook. Since the two programs use different file formats, you’ll need to use a converter program. Yesterday, I introduced you to a free program and showed you how to download it. Click here to read that article. 

Once you have your conversion program installed, you’ll need to export the data from the Thunderbird email client. Open the Thunderbird inbox.

Click Browse to select your destination folder. I’ve already created a folder called Thunderbird Exports in my Document library.  Then click on OK.

Go back to your inbox and select the folder you wish to export. Right click on the folder. Choose ImportExport Tools and then Export folder with subfolders.

Now you can convert the files. Open the MBOX to PST converter. Choose your source file and a destination folder and then Run. After the conversion is finished, click on Save.

There are a lot of steps involved, but the process isn’t really complicated by itself.
