I-Thunderbird Community Forum

A couple of months ago Thunderbird installed a new version (150.0.2) that made me enter a new identity. After I did that, I tried importing the e-mail folders from the earlier version (139.0), but totally without success. So I tried re-installing an older version, but this also, was no longer able to import the folders stored on my hard drive. What can I do????

I have tried severals methods to import a pst file from outlook to thunderbird but no success.

To be clear, I have a new computer which I don't use outlook with. Then, fomr my old computer I have reduce my pst file less than 2G. I have installed the importexporttools NG extension but i cannot import this pst. If i want to convert the file, i have to pay. I don't want because i need to do it once only.

Who can help ?

I am trying to import some mbox files to help sort scrape and sort my emails for a long ongoing complaint with my housing. However I can’t get past finding the local folder to then import the mbox file? Does anyone know where this is? I am using latest Thunderbird 153.0 and MacOSX Tahoe 26.5.1 Thank you.

I want to make a local back-up not only of my local Thunderbird folders, but also on the on-line folders. I am using IMAP and as far as I get, using the "export options", you only back-up data in the local folder. How do I ensure that I get a local copy of also the on-line inbox (and all of its sub folders)

I;m using the Thunderbird import tool, but do not see the import for outlook. This has probably to do with the fact the my Thunderbird runs on the virtual Mint linux. (via VMWare). Outlook needs to be installed on the same system as Mint I suppose, and that is not the case. Does someone know a solution to this?

Linux Mint 2.3 (Cinnamon), VMWare Player 15, Windows 10, Outlook 2007. (the last 3 are not the latest !)

Changed my Email address and when I opened Thunderbird, my folders (35+) containing hundreds of Email disappeared. Need to find where they are hiding and reinstall. Thunderbird with new Email address is working correctly, except for the lost data.

In reference to the article [[Knowledge Base Article|http://mzl.la/1ApHiU3]], "Move Thunderbird data to a new computer", this misses the transfer of Local Folders.

The instructions only include moving the Thunderbird application data folder with profile information but does not include Local Folders, after completing these instructions the Local Folders will not be present on the new computer.

The path for Local Folders is under Account Settings > Local Folders, this folder needs to be copied to the similar path on the new computer as well.

I have copied emails from a Windows 10 to Windows 11 computer using these instructions and it appears to work.

I had to update my server settings in Thunderbird since I changed my email hosting provider. I had no idea I would lose all my emails and folders I created. Is there any way to get these recovered?

My provider changed from q.com email to myctl.net email. I was using outlook but it wasn't downloading new emails. They are on provider web mail. When I downloaded Thunderbird it asked about importing from Outlook and I did. Now it is trying to download the 36,000 emails on the server site and going very slowly and I can't open the ones it has downloaded, I think because it was sent to q.com. Can i uninstall Thunderbird and then set it up again without importing anything?

I’ve set up a new email service type, IMAP, to take the place of my old POP email. The POP email doesn’t have a synchronization and storage feature, so I’m wondering: First, how can I combine the old POP emails with the new IMAP address; and second, how do I transfer drafts and sent emails from the old to the new one?

Had a double disaster, both OS partially upgraded at same time due to space issues and had to wipe and install.

Ended up with a TB install in Ubuntu where 2025 emails are missing. (see image #1) Found out that my backup should have most of them. (see image #2)

How do I safely identify the 2025 mail content in my backup folder, and how do I safely copy them over to the existing set up?

I see that the 933 profile exists in both so most likely it should be one of the lower number profiles in backup I need.

Attached are images of folder content.

Many thanks in advance!

I lost my windows 11 computer, and need to restore all my missing Local folders in my new computer that I have just installed Thunderbird. I think I need to delete everything under c:\user\myname\appdata\Roaming\Thunderbird\*. Tried this and still no Local stored emails found when I brought up Thunderbird? I have years of data stored there and really need them.

Dear Team, I have to download approximately 9000 emails in the inbox/ sent folders saved in yahoo with attachments. Though I could download after spending a week, unable to see the downloaded messages. Please inform how to proceed. Thanks. p.s: As suggested by chatgpt, I selected all messages in both the folders and downloaded them again. Please suggest best way to download the messages quickly and verify the contents. Thanks for your help. -Mani

Здравствуйте!

Пытаюсь подключить Яндекс.Почту к Thunderbird, чтобы скачать письма с Яндекса на компьютер.

Проблема такая: при добавлении аккаунта Яндекс.Почты в Thunderbird меня почему-то перебрасывает на авторизацию Google. Возможно, это связано с тем, что ранее почта была мигрирована на Google-аккаунт с таким же адресом и доменом, либо ящик Яндекса сейчас неактивен (он не оплачен, там просто старые письма лежат) — точно не понимаю.

Подскажите, пожалуйста:

Почему при подключении Яндекс.Почты Thunderbird может открывать Google-авторизацию? Можно ли принудительно подключить Яндекс.Почту вручную? Если ящик Яндекса был ранее связан/мигрирован с Google, есть ли способ всё равно скачать письма именно с Яндекса?

Моя цель — получить локальный архив писем с Яндекс.Почты на компьютере. Буду благодарна за пошаговую инструкцию, что проверить и как правильно настроить подключение.

I have been trying to archive my 25 years of Yahoo mail before they delete most of it. I thought I had it done. Now I have had to start again. Did you know that setting Thunderbird to ISAM download all your emails will only get the first 10,000 of any folder with more than that in it? Yes indeed, so it seems. We have to set the yahoo download server to the 'export' server. prefix the existing name with 'export'.

)

I am locked out of my yahoo accounts now. And the attempts I made earlier to delete stuff to make room have deleted stuff that never got downloaded/archived because from a folder with more than 10,000. That's how it goes. Just thought I'd warn anyone who might be as unknowing as I was. I took advice to the contrary and believed it.

I backed up my Thunderbird folder on my old pc, and moved it to my new pc. When I started Thunderbird, the appearance of the Inbox, plus my Address Book, was moved to the new pc. I don't see the Local Folders (and all the messages I put into the Local Folders) from my old pc, on the new pc Thunderbird app. I checked that the "Profile Folder" under Troubleshooting / Application Basics, was selected for the profile I moved from the old PC. I can see in the profile folder all the Local Folders. Any idea on how to get Thunderbird to recognize these transferred Local Folders and contents, so I can continue to access them on my new pc running Thunderbird ? Thanks

Hi!

I am trying to upload some backups after moving from one email platform to the other. The mailbox was deleted from the old platform and created on the new one and now I am trying to upload the backups but when the upload finishes, nothing happens, the profile stays the same, I don't see the backups added to the Thunderbird profile so that I may copy them into the new mailbox.

I have Thunderbird installed on a linux o/s running Zorin 18.1 the version of thunderbird is shown in uploaded images. I wish to export everything in my profile to a folder which Evolution can access when asked to import. I then intend to delete Thunderbird and carry on with Evolution as my email app of choice. In anticipation John
