When I added my treasurer@mlakes.org email to my Thunderbird account all of my previous contacts were not included. Can they somehow be added ?

I have Version 140.8.0esr | Released February 24, 2026, for Linux Mint (up to date)

I have a CardDAV address book on a Nextcloud instance that i want to sync to Thunderbird.

When i open Address Book and the clikc on " Create a new address book" the Account Hub modal window opens. None of the 4 options (including Add Remote Address Book" do anything, i.e. I can click as much as I like but nothing happens.

I have a backup file from another thunderbird installation. The profile in this backup contains a file named abook.mab. I suppose this is the address book. I would like to copy the addresses from this installation to my current thunderbird 147.0.1 (64-bit). Tools > import > address book does not work. Can you please advise me?

I left outlook and chose tbird with cardbook. I am not happy with it. When I choose "new message" I get a blank form and can choose an individual addressee but do not have the option of addressing I group I created. My contacts are in google with supposed cardbook coordination. I think your contact list is interferring with the cardbook data. This is a kluge. How do I fix it

I deleted an old email address for a friend, but every time I email her, the auto-complete feature includes both the current email address and the one for her old job. I've deleted that one, and it doesn't seem to show up in the Address Book anywhere, so why does it keep coming up in the auto-complete?

It's annoying to me and to the place of employment to have the emails go to the wrong address when I'm not watching very carefully.

How can I make sure this doesn't happen again?

Recently, I exported my Address Books, i.e., Personal and Collected as CSV files. Looking through those files I discovered that not all "Fields" from the Address Book had been included during export. Some of my contacts include three or four email addresses. The CSV Header added to the top of my exports only shows "Primary Email" and "Secondary Email" in the Header. There may also be other Fields of information that are not exported, but I haven't looked and, frankly, didn't expect to have to check my exported files. When editing a Contact if that contact has more than two email address I expected those to be part of the export file. I am running the current version of Thunderbird on my Windows 11 computer and an earlier version on a Windows 7 computer. Both versions of Thunderbird do not export all Field Data from the Address Books.

Trying to set up a mailing list for emails. Not sure how to set up a group that I can use to list names and emails. Went to help. Instructions said to > open address book > select file > new > mailing list. I went to address book ok but cannot find 'File' there.

Am after assistance in getting mailing list set up.

Thanks

I tried importing my Outlook Classic address book. As you can see from the attachment, I really messed it up!. I am not technical at all, I wasn't sure if I needed to import my contacts or my address book. I think, but am not really sure, that I exported my .pst file, address book to a csv vile. Can anyone one straighten me out? If I have to start over, how do I delete the mess I created without loosing all of my other settings? Thank you very much 😊😊😊

Address book import is not working after I import it. It says I have 516 contacts. All I see are big grey dots but no information inside them.

I'm exporting from Classic Outlook (2016) in .CSV format.

Thunderbird still syncs Gmail contacts even though I have no Gmail account in TB. I imported a Vcard into TB and deleted a couple contacts. Went back into Gmail contacts and had to restore them.

Why does this happen?? James

I am using TB 140.9.0esr (64-bit) on Kubuntu 25.10 but this has been true for some years. Mostly when a start a new Email address whether in the To:, cc: or bcc: fields TB does a very good guess after a few letters about the address I want. However, every so often, perhaps 5% of the time it will pick the correct person but I won't notice that it has picked an old address for that person. It seems to happen in bursts, so three times in the last few hours for two different addressees. I realise that I could shift the old addresses for people to the notes section of the address book but I would rather not as I am hoping that one day TB will have the ability to search for all Emails to/from someone across all the addresses they ever had, current or deceased. Is there a way you can stop TB suddenly changing its guesses about the addresses for a person? Or could you add a way to tell TB in the address book that addresses are dead and should never be offered as addresses to send to?

TIA,

Chris

I run TBD 140.8.0 esr (64 bit) under Debian 12 Linux. Until recently I could automatically enter a special address from the pertaining addressbook, this does not work anymore. helpfiles do not show a solution thus I am here.

The addressbook is full of addresses however I have to transfer a special address via past and copy into the addressfield of the mail I want to send.

Thanks for a quick answer Jörg Kampmann

I recently installed Thunderbird on my Android pad where all my email contacts came in fine. However, I just went to my Windows 10 laptop where I've previously used Thunderbird and my contacts are missing. How do I get them back to my laptop?

I would glad donate to TB Mozilla IF it would work the way it is supposed to. I tried for 3 hours to create a MAILING LIST nut to no avail. The instructions make no sense.

Also in my Address book that I imported, phone numbers show up under the heading "email addresses...and I have email showing up at all.

Merci de votre boulot pour cette vertion mais prevenez que le carnet d adresse est ... !!!!!!!!!!!!!!!!!!! Cordialement David

Hallo, die Kontakte im Adressbuch werden mit Carddav zu meinem Mailaccount (IONOS) nur teilweise syncronisiert. Die Syncronisation endet bei 1000 Einträgen, ist das so gewollt oder kann ich dies ändern? Fehlermeldungen gibt es dazu keine. Die betrifft die Thunderbird un Linux Ubuntu. Ich Thunderbird Windows 11 funktioniert alles.

Liebe Grüße Peter
