If you need to process 20 user accounts or more, please visit our “Large-Scale Migration” page.

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.

Thank you for choosing Aid4Mail. With one license, you can process all your mail accounts on a single PC and Windows login account. It’s also fine to run Aid4Mail on a second PC to transfer your mail to it. But if you must migrate mail stored on 3 different PCs, or belonging to 3 different people, then you’ll need 3 Aid4Mail licenses. You can set the number of licenses on the next screen.

Double-check the system requirements here…

  • 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.

IF YOU’LL BE PROCESSING OUTLOOK/EXCHANGE:

  • 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).

Aid4Mail can read mail from:

  • Microsoft Exchange through Outlook/MAPI (1) (except Aid4Mail Home) or IMAP (2),
  • Outlook Personal Storage files (1) (*.pst),

  • Adobe Acrobat PDF files (not available in Aid4Mail Home),
  • Aid4Mail ZIP archives (*.zip).

Notes:

  1. To process (from/to) Outlook MSG files, PST files, and Outlook/MAPI mail profiles, Aid4Mail requires either a 32-bit version of Office Outlook or a standalone version of MAPI. For details, free options, and limitations, see the System Requirements.
    Only Aid4Mail Console can export a source MAPI profile or PST file to a target MAPI profile or PST file. With Aid4Mail Home, Aid4Mail Professional, and Aid4Mail eDiscovery, the workaround is to first export your emails to the Outlook MSG format, and then re-export those files to your target format.
  2. Microsoft Exchange can either be processed through an Outlook/MAPI mail profile (1), or through the IMAP protocol in which case the Exchange server needs to be set up for IMAP access (see instructions).
  3. Aid4Mail cannot process encrypted The Bat! mail files. In this case, you will first have to export your messages with The Bat! to a Generic mailbox format, which Aid4Mail can then process to any of the supported formats.
  4. Aid4Mail currently does not offer tools to convert address books, filters, or account settings from one format to another.
This low-cost option is for home users and students to use on email that is NOT work-related.

If you’ll be processing mail for your business, nonprofit or other organization, then you need Aid4Mail Professional.
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!
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.
To transfer your own mail from an old computer to a new one, a single license is sufficient. However, you can’t use an Aid4Mail license on multiple computers at the same time, as stated in the EULA.
To do this you must have a license for every person whose mail is converted, in accordance with the EULA. If not, your license will be locked automatically. Note that purchasing additional licenses later is more expensive than buying all the licenses you need together in one order.
Yes, as long as you have purchased the correct number of licenses for your clients, in accordance with the EULA. For example, to process 3 people’s mail or mailboxes stored on 3 different PCs, you’ll need 3 licenses. If your client is a company, you’ll need the appropriate license(s) to cover their needs. Once you’ve used a license for one client, you cannot transfer it to another client.
Your license will be sent by email immediately after your order is accepted. If you haven’t received it within a few minutes, please check your spam folder before contacting us.
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.
