Export Thunderbird to Outlook

Two Ways to Migrate Thunderbird to Outlook: One Simple, One Free

Converting your email from Thunderbird to Outlook? Unless you’ve found a converter you can trust, you’re faced with a challenge.

  • Outlook won’t import your mail from Thunderbird.
  • There aren’t many free or low-cost email tools that support this conversion.
  • The solutions most often recommended on the Web have significant drawbacks.

And here’s the worst of it: You know if you make the wrong decision, you could end up wasting hours of your precious time and still lose your valuable email data.

But don’t worry! A good solution does exist.

In a moment, we’re going to tell you about a conversion tool that’s perfect for your needs. It’s an affordable tool that was designed specifically for this type of email conversion challenge. Most people agree that it’s a huge time saver, but in the interest of fairness, we’d also like to tell you about a free method for getting your conversion done.

The free method is great if money is tight. The other is better if you value your time and accurate results. Keep reading to know which is best for you.

Export Thunderbird to Outlook – the Free Way

This method requires four programs: our free MBOX Converter, Windows Explorer, Windows Live Mail (WLM) and Office Outlook. However, the Thunderbird program is not required.

Start by installing Aid4Mail MBOX Converter and Windows Live Mail if you haven’t already got them on your computer. You’ll need to download Windows Essentials to install WLM.

First, convert your Thunderbird files to EML with Aid4Mail MBOX Converter.

  1. Open Aid4Mail MBOX Converter.
  2. Click the Choose Source Files tab and select Thunderbird from the list.
  3. Next add the root folder of your mailboxes to the list by clicking on the Add Folder button.
  4. Click the Set Target Options tab or the Next button.
  5. Next select the EML files option near the top of the list.
  6. Confirm or change the target folder name.
  7. Click the Start Conversion tab or the Next button. Then click the Start button.
  8. Close Aid4Mail MBOX Converter once your mailboxes have converted to EML files.

Then follow this 14-step procedure for converting EML files to PST. (This is based on Windows Live Mail 2012. Other versions may differ slightly.)

  1. Open the Windows Live Mail program.
  2. Select the Folders tab and click on the New folder icon to open the Create Folder dialog box.
    Type a folder name, select the folder in which it should be created, then click OK.
  3. If you have multiple folders with EML files, repeat step 2 until you’ve recreated the folder structure of your source EML messages.
  4. Select the target folder for your EML files in Windows Live Mail.
  5. Select your EML files in Windows Explorer and then drag-and-drop them into the email list panel in Windows Live Mail.
  6. Repeat steps 4 and 5 for every matching source folder containing your EML files.
  7. When you’re done, the contents of your target folders will match those of your source folders.
  8. Now click on the dark blue tab with the “down” icon in Windows Live Mail.
  9. Point to Export email in the drop-down menu, and then click Email messages.
  10. In the Windows Live Mail Export wizard, click Microsoft Exchange and then click Next.
  11. Click OK when you see this message:
    This will export messages from Windows Live Mail to Microsoft Outlook or Microsoft Exchange.
  12. Choose your target profile name in the Choose Profile dialog box, and then click OK.
  13. Click All folders to import all your messages, and then click OK. Or, click Selected folders, choose the folders that you want to export, and then click OK.
  14. Click Finish when the Export Complete screen appears.

You should now see your mailbox folders and messages under Imported Folder in Office Outlook.

As you can see, exporting Thunderbird to Outlook without a conversion tool can be a cumbersome process. Sadly, it isn’t always accurate, either. In conversions using this free method, email contents can get lost. Let me explain.

“Free” Often Includes Hidden Costs

When it comes to email conversion tools, you typically get what you pay for. While you may still choose the free method, you need to be aware of your potential risks.

  1. Broken images. After migration with Windows Live Mail, photos, graphics and other images inserted in your messages now show up as broken pictures in Outlook. They aren’t visible in the body of your emails (see screenshot below.)
  2. Loss of SMTP headers. Using the free method, your emails will lose their original email SMTP headers (the top part of the email, where email addresses, subject and time stamps, and encoding marks are located). If you value the integrity of your messages, especially if you work in the field of computer forensics, this is a serious problem.
  3. Time consuming. If you have many accounts to migrate, transferring your emails manually will take a lot of time and energy.

The screenshots below show the result you get using the free solution (left) compared to using Aid4Mail Professional (right):

It’s true. “Free” may initially appear to be a cost savings, but when you factor in the hours it takes to migrate your emails—and the low-quality outcome—you may actually save money using a commercial tool.
