Migrate Eudora Data (Thunderbird-Win)

Follow the steps below to migrate your Eudora messages into Thunderbird for Windows. Instructions below only cover the latest version of Thunderbird we support; instructions for previous versions may be similar, but not exact.

Note: Migrating your Eudora messages may not migrate attachments that are included with those messages. Your attachments will still be accessible though Eudora in the Attachments Folder. If you wish to delete Eudora from your hard drive, you should first archive attachments that you want to save.
