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.

How to Export the Simple Way

For quick and easy email conversions that don't sacrifice quality, there's only one tool you should consider: Aid4Mail. It costs a bit (not much though), but the time it saves you over the free method is really worth it. Here's why…

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 only need Office Outlook installed. Mozilla Thunderbird is not required.
  • And, if necessary, you can also export your messages directly to Office 365—or to Microsoft Exchange—using our Aid4Mail Professional edition.

Here's how it works…

  1. Open the user-friendly wizard interface.
  2. Select Mozilla Thunderbird as your source and Office Outlook PST file as your target.
  3. Click Next until you reach the last screen and then press Start.

That's it!

We've made the entire process as streamlined as possible. Aid4Mail provides context-sensitive help on each wizard screen (in addition to a well-documented user manual), so it's easy to learn—even for first-time users.

Aid4Mail is very competitively priced—as low as $29.95 US per license. But if that's too much for you—and time and accuracy are not so important to you—consider using the free method explained in the next section.

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. Read more >

No doubt, like our clients, you'll prefer the simple solution over this free method.

NOTE: Aid4Mail supports all versions of Mozilla Thunderbird and the 32-bit version of Outlook 2010/2013, as well as Outlook 2007, 2003, 2002, and 2000.

Please check if your computer meets the System Requirements before buying!

  • Operating System : Aid4Mail runs under Windows 8, 7, Vista, XP, 2000, Server 2012, 2008 and 2003 or Linux in conjunction with Wine. Both Windows 32-bit and 64-bit are supported.
    Windows NT4 / ME / 98 / 95 should work but are not officially supported.
  • Internet : Online license activation, validation, and re-activation require an internet connection (offline activation option available with Aid4Mail eDiscovery editions).
  • Hardware Requirements : 64 MB of RAM, 12 MB disk space. Pentium (or compatible) processor.


  • Aid4Mail currently does not support the 64-bit versions of Office Outlook 2010 or 2013. But Windows 64-bit with Outlook 32-bit is fine.
  • Office Outlook (32-bit version) must be installed to process mail to or from Outlook/Exchange profiles, *.msg and *.pst files.
    If you don't have Outlook, you can use Microsoft's free 60 day trial of Office Outlook for Windows. Alternatively you can use their free standalone version of MAPI but note that it doesn't support Unicode PST files (which may be used in Outlook 2003 and later versions).
  • Aid4Mail may not be compatible with Click-to-Run installations of Outlook 2010; you will need to re-install Outlook 2010 using another method following Microsoft's instructions. This is not the case for Outlook 2013 which works fine with Aid4Mail 3.
  • If you have Outlook 98/2000 then it should be installed in Corporate/WorkGroup mode in order to process PST and MSG files. If it is installed in Internet Mail Only (IMO) mode, then only the default MAPI profile can be processed.
  • There may be compatibility issues with Outlook 97.
  • PST files from Outlook 2001 for Mac are supported, but not those from Outlook 8.x for Mac. Outlook 2011 for Mac can import PST files created by Aid4Mail.
  • Microsoft Exchange can either be processed through an Outlook/MAPI mail profile, or through the IMAP protocol in which case the Exchange server needs to be set up for IMAP access (see instructions).

Text in gray font indicates email formats that are unavailable based on your current selection.

A Two-Week license is intended for a one-time email migration or conversion. It's valid for 2 weeks from first activation. This should give you enough time to experiment and then carry out your migration/conversion.

But consider this. If you spend just a little more, you get a One-Year license that you can use for other useful tasks – like email archiving, email data searching and extraction, and more… And it's renewable in future years with a 50% discount!
PayPal and all major credit cards are accepted. You can also use a purchase order if you're a registered business and your order exceeds 100 USD.

Your personal license details and a printable invoice will be delivered to you by email immediately after your order is accepted.
Yes. Your order will be processed by cleverbridge via the secure SSL protocol, so your private data remains safe and confidential.
We offer big quantity discounts, but they can't be spread over multiple orders. So make sure you buy all the licenses you need now to get the best price.

You can set the quantity on the next screen after you click on the green button.
First, you get to try before you buy. There's no better guarantee than putting Aid4Mail to work on your own system before making up your mind. If Aid4Mail works for you during the trial, you can be sure it'll work when you get your license.

Second, our complete Quality Assurance Guarantee. After your purchase, if you're unhappy with Aid4Mail's performance for any reason, contact us immediately for a quick and easy resolution.
No. Like many other programs, Aid4Mail currently only works with the 32-bit edition of Outlook. Most users, even those with Windows 64-bit, have Outlook 32-bit installed.

Note that Aid4Mail is fully compatible with Windows 64-bit. See the System Requirements for more details.
