I need to import my mail messages, exported from Mac OSX Mail, into Thunderbird on Windows 11. I have 2 versions of the Mail exports: i) i backed up the Mail folder from the System folder These are [ .emlx ] files in [ .mbox ] folders ii) I exported direct from the Mail app These are [ .mbox ] folders

Thanks for any advice I can get, Steve

How can I transfer total messages including date and addresses to a word document for layout and summarising. I used to do this perfectly well in Windows Live Mail for many years!!!!

I followed the recommended procedure to transfer the TB profile from an older W10 computer to a new W11 computer (both using POP accounts ), via a USB Flash Drive. The folders are all listed on the USB profile copy and observed during the scrolling detailed view while being copied to the new computer. Nevertheless, they are NOT listed in Local Folders on the new profile. Instead, ALL the messages (approx 700 of them!) are presented as UNREAD in the inbox folder. How can I restore the original folder sorting?

‘I have a series of mails 19 plus attachments that I wish to send to my bank i need to copy them and convert to PDF format. I can find no way to copy them out of my inbox’ for ‘Thunderbird’

Bonjour, je pratique THUNDERBIRD depuis de très nombreuses années et j'en suis très satisfait. D'ailleurs j'ai contribué à des donations au cours de l'année précédente. Je viens de constater tout récemment plusieurs choses qui me gênent : 1) je ne vois plus apparaître la commande "insérer" pour insérer une image dans un texte 2) quand j'enregistre un message pour le sauvegarder je ne vois que le texte du message, mais plus les entêtes (adresses e-mail, date, etc.). Pouvez-vous me donner des explications s'il vous plaît ? Merci par avance. Guy ROBIN guyrobinggl@gmail.com

Hello, I have been using THUNDERBIRD for many years and I am very satisfied with it. In fact, I contributed to donations during the previous year. I have just recently noticed several things that bother me: 1) I no longer see the "insert" command appear to insert an image into a text 2) when I save a message to save it I only see the text of the message, but no longer the headers (e-mail addresses, date, etc.). Can you give me an explanation please? Thank you in advance. Guy ROBIN guyrobinggl@gmail.com

Hi! I am trying to use the Thunderbird application to help me view a huge '.mbox' file from an email account that is no longer active. I have the entire file saved to my computer as I downloaded it before the account was closed. Can you help me access those files? I am working on a huge project and really need to look for date sand times of emails sent in the mailbox so that i can piece together the timeline of the project. I would greatly appreciate this!!!

Hello everyone,

I am using Thunderbird with a work email account that is based on Gmail (IMAP).

My question is: How can I make sure that I will still have access to my emails in Thunderbird if my company deletes the Gmail account in the future?

Specifically: 1. Which Thunderbird settings ensure that emails are fully stored locally? 2. Is “offline use” of folders sufficient, or are there additional steps I should take? 3. Are there any caveats with Gmail/IMAP I should be aware of?

Thanks a lot for your help!

Have asked this question before and last time it finally work, now nothing works

Have tried so many times to transfer from old laptop to new laptop, nothing works. Have watch the youtube videos and followed this. Can not get it to work.

and what does this mean three levels up to the AppData\Roaming folder

Just want the emails from the old to the new laptop Thank you

hello,

i am trying a second time to submit my question:

how can i migrate 3 months of prior thunderbird emails from a docked ssd to the ssd installed in my computer. please see attached photo.

the migration must be done without creating duplicate emails for the months of January 2025 through August 2025. more importantly, i don't want to disturb or lose the emails of December 2025 and January 2026 that are now on my computer. so my simplistic analysis is that i have to be able to move hand-selected emails from the docked SSD to the SSD installed in my computer. otherwise if i move an entire profile, it will erase my current profile that includes December and January emails.

thank you

I have an email account with Eclipse which is closing down. How do I transfer emails from eclipse to a gmail account? How can I make sure anyone trying to use my old eclipse account will have those emails automatically sent to my new gmail account?

Dear Thunderbird Support and users I have encountered a problem when changing email provider - the inbox folders that holds most of the messages are no longer visible in Thunderbird. The messages can be found when searching for them - i.e. by searching for a specific email address or message header.

The procedures followed were:

1) connect Thunderbird to email provider 1 2) configure Thunderbird, so all messages are preserved/saved locally, so no messages would be deleted from server or from the client 3) Test if messages are saved, by disconnecting from Internet - All messages in their folders were there 4) Change email server settings and DNS settings to enable Thunderbird to connect to the new email provider (email provider 2) 5) Start Thunderbird and enter password.

- That is where it went wrong, all the inbox folders disappeared

I have checked, and the names of all the folders are preserved in the folderTree.json file, but it doesn't seem to want to synchronise with the new email provider 2.

Do you have any suggestions as to what should be done to recover the inbox folders with all the messages?

With kind regards, Jesper Tae Jensen

My old laptop crashed and burned, but I had a profile backup. I used the transfer tool to install the profiles on my new computer, but had a couple problems: 1- the calendar didn't transfer over. I fixed this by copy/paste Calendar-Data and calendar-data.sbd from the default-release folder . 2- No sent records were copied over. I tried copying over a sent.file (375 mb) and sent.msf from a different default-release folder (there were two default-release folders in the older profile backup, I'm not sure why). This did not update the new installation with the sent records. So my question is, how to I update the sent folder in the new build from a older backup, so that all the records are included. Win11 up to date with latest Thunderbird and Firefox versions. Thank you.
