Switching from Apple Mail to Thunderbird

Thunderbird can import your messages and OS X address book, but it cannot import your account settings. (Currently, message and address book import is only functional with Apple Mail 5.0 or earlier.)

Importing Apple Mail messages

  1. On the menu bar, open the Tools menu and click on Import. The import wizard will open.


  2. Select Mail then click Next.


  3. Select Apple Mail then click Next.


  4. You will see a log of successfully imported folders, then click Finish to close the import wizard.


Your imported messages will appear in the Local Folders account, in a folder called "Apple Mail Import".

Importing the OS X address book

Thunderbird will read your OS X address book and display it in the Thunderbird address book window! From the menu bar, open the Window menu and click on Address Book. Your OS X address book will appear in the left pane.

If you want to import it to the Thunderbird address book, just drag and drop entries from the Mac OS X address book folder to the Personal Address Book.

Note: You can select all entries at once by holding down the command key and pressing A.

Switching from Windows Mail or Windows Live Mail to Thunderbird

Windows Mail is the default mail client included with Windows Vista. Windows Live Mail is the email client bundled with Windows Live Essentials. Both client programs store emails in the .eml file format. In order to export messages from Windows Mail or Windows Live Mail to Thunderbird, you must export messages from the Windows application and import them into Thunderbird. A similar method is needed to export contacts from Windows Mail or Windows Live Mail to Thunderbird.

To find the location of the email files in Windows Mail or Windows Live Mail, go to Tools | Options | Advanced | Maintenance | Store Folder.

Importing Windows Mail Messages

Importing Windows Mail (.eml files) into Thunderbird is enabled by the third-party add-on ImportExport Tools. Download and install this add-on to transfer messages from Windows Live Mail to Thunderbird.

  1. Export your messages from Windows Mail in .eml format.
  2. In Thunderbird, go to Tools | ImportExport | Import all messages from a directory | Also from its subdirectories.
  3. Navigate to the .eml files folder. The default location for Windows Live mail is C:\Users\<username>\AppData\Local\Microsoft\Windows Live Mail (or \Windows Mail).NOTE: To be able to see the folder "App Data" you must first change Folder Options to "Show hidden files, folders, and drives"
  4. Click Open. Your data will be imported.

Importing Windows Mail Contacts

In order to import Windows contacts into Thunderbird, you must export the contacts to a text file (.csv format) and import the file into Thunderbird. See the Import, export, or change the format for contacts article at Microsoft.com for instructions on how to export contacts in Windows 7.

After creating the required file, you can import your contacts using the instructions for importing Outlook 2007 contacts below. However, instead of choosing Outlook in step 3, choose Text file (LDIF, .tab, .csv, .txt) and click Next. In the Select address book file window that appears, select Comma Separated (or All files) in the drop-down list at the bottom right, browse to the .csv file you just created, select it and click Open.

In the Import Address Book window that appears, use the Move Up and Move Down buttons to match the address book fields on the left to the correct data for import on the right, and uncheck items you do not want to import. When you are done, click OK. Your contacts should now be imported and ready for use in Thunderbird.

Note that if you are having problems importing the fields properly (like when all record data to import shows up inside the first field row when inside the Import Address Book window), this is probably a result of an exported .csv file containing semicolons instead of commas, or the other way around. This usually happens because the separator in Windows Regional settings does not match the one for the Thunderbird locale, for instance when you exported a .csv file using an English Windows version and try to import it into a non-English version of Thunderbird. In this case, you should make the list separator match in your Regional settings before exporting the .csv file, or you could edit the already exported .csv file using a text editor and replace all semicolons by commas (or vice versa), and retry the import step.

Switching from Outlook 2007 to Thunderbird

The following instructions describe how to import messages and contacts from Outlook 2007.

Importing Outlook 2007 Messages

In order to import messages from Outlook to Thunderbird, Outlook must be the default mail client.

1. In Thunderbird, go to Tools | Import….
2. Choose Mail and click Next.


3. Choose Outlook and click Next to start the import process.


4. The Import Wizard will process the emails and display the results. Click Finish.


The emails will now be stored in a folder called Outlook Import under the Local Folders directory.


Importing Outlook 2007 Contacts/Address Book

1. In Thunderbird, go to Tools | Import…. 2. Choose Address Books and click Next.


3. Choose Outlook and click Next.


4. Wait for the import to finish and click Finish.


Importing PST files

Thunderbird cannot import a standalone PST file. Mail import from Outlook works by using the Outlook program to source the emails, not the underlying PST file. If you are switching to Thunderbird and will no longer have a copy of Outlook then it will be necessary to convert all of your existing PST backup files to Thunderbird while you still have access to Outlook on the same computer as Thunderbird.

Switching from Evolution to Thunderbird

The following instructions describe how to import messages and contacts from Evolution.

Importing Evolution Messages

Thunderbird and Evolution use the same file format (called mbox) to store your mails, so its not difficult to import them manually.

  1. Open Nautilus.
  2. Open ~/.local/share/evolution/mail/local which is where Evolution store your mails.
  3. Copy all the file without extension (such as Inbox, Outbox,..) into the emplacement used by Thunderbird to store its mail (something like ~/.thunderbird/uk41lql0.default/Mail/Local Folders,where you need to adapt uk41lql0.default to your own installation).
  4. Launch Thunderbird to check that all your mail have been correctly imported.

Importing Evolution Contacts

  1. Open your address book in Evolution, right-click on it and choose: Save as vcard... to export it into vCard file format.
  2. Import this file into Thunderbird:
    1. In Thunderbird 3 and 3.1, you need to install the MoreFunctionForAddressBook extension in order to be able to import vCard file. Once this is done, open the Address book window, right click on the entry area and select Import vCard/vcf. Select the .vcf file that you have just saved.
    2. In Thunderbird 5 or above, open the Tools | Import... menu, select Address Books and then vCard file ( *.vcf) and select your contact file.

Switching from Web-based Email Applications to Thunderbird

If you are using a web-based application provided by your Internet Service Provider (ISP) to access your email, you probably only need to configure your account information to switch to Thunderbird. See Manual Account Configuration for instructions. Also, see ISP Configuration Settings for instructions on specific ISPs.

Once you have configured your account in Thunderbird, you should be able to access all your messages (both incoming and sent). However, your address book (contacts), mail filters and other settings will not be automatically transferred to Thunderbird.

Some web-base email applications allow you to export contacts in text or comma-separated formats. Check your ISP's documentation for more information. To import contacts into Thunderbird, select Tools | Import… and follow the instructions on the screen.
