Importing from Eudora - Thunderbird

From MozillaZine Knowledge Base

Thunderbird must be able to find the Eudora data. So either Eudora must be installed, or you must create a registry entry that points to the Eudora data.

Thunderbird data import is not always successful; there are many variables such that you may get bad messages, crashes, etc. So it is recommended that you backup Thunderbird and Eudora data prior to doing imports, so that if a problem does occur then you have the data needed to troubleshoot the issue, and rerun the process at a future date. Keep your original data for an extended period of time so that if a problem is found then you have the data needed to reproduce the problem such that someone can fix it.

Automatic importing

To migrate from Eudora to Thunderbird:

  • When starting Thunderbird for the very first time, migration is invoked and the Import Wizard will pop up, and you can then select the "Eudora" option to import your mail, address books, and settings.
  • Subsequent to launching Thunderbird for the first time, you can use "Tools" menu, select "Import...", and then individually import your mail, address books, or settings from Eudora.

Importing Attachments

The two programs store attachments differently: Eudora detaches them from the e-mail and stores them separately as files, usually in a folder named "Attachments" or "Attach". Thunderbird keeps the attachment together with the e-mail.

When importing from Eudora, Thunderbird attempts to join the attachment back to the e-mail it came with. This can take quite a long time if there are a large number of attachments. Also, because they include the attachments, Thunderbird's mailbox files are larger than Eudora's, though that is usually harmless.

If you want to prevent Thunderbird from re-attaching the attachments, you can try to move the folder containing Eudora's attachments to a place where Thunderbird will not find it. IMPORTANT: Do not delete Eudora's attachments folder or you will lose all your attachments. Also, please note that this solution is untested; use it at your own risk.

Importing Eudora Mail with Eudora Rescue

The following issue is fixed in Thunderbird v3 by bug 368347. Note, Eudora Rescue has not been updated since 2005.

Thunderbird 1.0 and onwards has improved importing of the Eudora e-mail, but it still cannot maintain the messages' status. Until this is fixed, perhaps the best method of conversion is with the use of the Eudora Rescue utility by Qwerky. See the README for instructions for using Eudora Rescue. After you have used Eudora Rescue, you can import the mbox into Thunderbird or Mozilla Suite using the ImportExportTools extension.

Importing Eudora Mail with Eudora Mailbox Cleaner

Although it only runs on Mac OS X, you can use Eudora Mailbox Cleaner to import your Eudora messages from either the Mac or the Windows version of Eudora instead of using the import function built into Thunderbird. Eudora Mailbox Cleaner should be able to

  • preserve all formatting of rich text and HTML messages
  • correctly import non-ASCII (8-bit) characters
  • preserve message status flags (such as read, replied, and forwarded)
  • and re-attach attachments for received messages, unless they have been moved or deleted from the Eudora attachment folder.

Windows users who have had no luck with Windows native tools, might experience better results transferring to a Mac, converting and then transferring it back.

Address books

The easiest solution is to use the automated import of the address books. However, you could also

  • Select Tools -> Address Books in the Eudora menu .
  • Chose File -> Save As .
  • Select CSV Files (*.csv) under File Type .
  • Type Contacts under File name .
  • Click Save .
  • Import it in Thunderbird using Tools -> Import -> Address Books -> Text Files.

This will not import the mailing lists , which are stored separately.

Outgoing Attachments Fixer

If Thunderbird didn't migrate attachments for sent messages use the Outgoing Attachments Fixer program to modify the *.mbx files and then import them again using the Tools menu. The program is run from a console window. For example:

java -jar EudAttachFixer.jar "C:\Eudora" "C:\Eudora\FixedMailboxes"

Filters

Thunderbird 2 doesn't support importing filters so there is no support for importing .pce files. Thunderbird 3.0 does support importing filters but its not clear yet exactly what functionality it provides
