To view your address book, select Tools then Address Book.
Note: In some cases, the address book data will not import into Thunderbird. A workaround has been found:
- Import the Eudora csv file into the Windows address book.
- Import this address book into Thunderbird.
The built-in utility of the Windows address book works much better at adjusting the information to agree with the labelling within the address book. This process required no editing afterwards within Thunderbird
