How can I clear the stored auto-complete e-mail addresses in Thunderbird, without clearing everything?

more options

In the auto-complete of e-mail addresses, old invalid addresses keep appearing in this list that are not in any address book (any more). How can I delete one from the list, or perhaps all?

Chosen solution

The only place that Thunderbird gets suggested addresses is from your address books. I have seen some not show up in the books because some key info was never stored when the contact was saved. Sometimes you can start a new message and when the bad contact shows up select it. Create the message and save it to drafts. Then you can go to the Draft folder open the draft message by right clicking and select Open Message in Tab. Then click the star to the right of the contact and it will open the contact edit button. From there you can delete the contact. This does not always work though.
