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

If you’ve tried converting your emails before, you already know how painful it can be. Thunderbird’s mbox files don’t convert easily to Outlook. When you try workarounds and free downloads, you get:

  • Messed-up folder structures
  • Incorrect message dates
  • Lost data
  • Missing email addresses, status flags and time stamps (due to lost SMTP headers)
  • Broken embedded images
  • And, in many cases, painstaking hours of manual folder reordering

​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 valuable email data.

How to Export the Simple Way

With Aid4Mail you only have to go through three simple steps to get your conversion done. And you’ll love the results:

  • No data is lost in conversion.
  • It automatically restores your mailbox folder tree in Outlook without any manual intervention.
  • It correctly transfers the status information of your emails (like unread, replied, forwarded, and flagged) to Outlook.
  • ​You can export directly to Microsoft Outlook, Office 365 or Exchange.​

Still Want to Convert the Free Way?

This method is a lot more complicated and time consuming. But it’s by far the best free solution on the Internet. It requires four programs: our free MBOX Converter, Windows Explorer, Windows Live Mail (WLM) and Office Outlook.
