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 the three-line menu icon at the top right.
Choose add-ons from the drop-down menu.
The add-ons manager will open. Click Extensions in the left pane.
Search for Export-Import Tools in the search box.
Click on Add to Thunderbird. You’ll need to restart Thunderbird.
Once it’s restarted, click the three line-menu bar followed by add-ons. Then click the Import-Export Tool.
When the tool opens, click the Export Directories tab.
Tick the box next to Export folders as mbox files.
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.
Then open your Outlook inbox and choose File at the top.
Then Open & Export. Choose Import and Export from the center pane.
Chose Import from another program or file.
Select .pst file. Follow the instructions of the import wizard to finish the process.
There are a lot of steps involved, but the process isn’t really complicated by itself.
