TB will import but does not display either legible emails nor attachments. I suspect GM at is fault. The takeouts seem incomplete at Zip 11GB. There are 2407 emails in my simple GM account a few with always Adobe PDF legal document attachments. I am new to Thunderbird so that may be a contributor but it looks very straight forward. Perhaps I am a moronic 82? I represent 11,000 disabled Firefighters pro bono in UK and Ireland. Grateful for any help please...Paul

Hello,

I hope everyone here is doing well.

I am trying to change from Gmail to Yahoo.

I am using Thunderbird to migrate my Gmail account's emails to my new Yahoo account.

My Gmail account has thousands of messages, including numerous photos and other attachments.

My laptop doesn't have space for the app and everything necessary for the migration.

How can I use the Android app on my phone to accomplish this instead?

Please let me know as soon as possible.

Thank you so much!

Mac's Tahoe 26.5.2 is the last OS that will run my SeaMonkey 2.53.23. Is there a version of this or Thunderbird that is compatible with Apple's new chips? My main concern here is email, and the folders in which I have stored years' worth of messages. If I have to use the latest Thunderbird instead that's okay, as long as there is a version of Firefox that is compatible as above -- but I would need the Thunderbird to be able to access my old SeaMonkey mail files. Is this possible? I'm delaying the update while I figure this out., Thanks for any help you can provide. -- E. Brad Meyer, [redacted email from community support forum]

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.

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

I have an email address and I want to migrate those emails to a gmail address. The problem is that I have around 2300 emails. I'm copying about 200 emails to the gmail address. The problem is that is taking too long and it's not copying all of them.

What if I copy all of emails wait to sycronize it and then copy it again? It will work? Or is there another way to do that?

My computer crashed and I cannot retrieve my e-mail and I don't remember how to get to it. Had it for many years and just had an icon on the computer so I don't remember anything about it except Thunderbird. The e-mail address is [redacted from public] @metrocast.net Can you please help me find it?

Good morning . . . I have recently switched from an old Windows 10 machine to a new macmini, and have switched my Office 365 account over to it. Simply stated, Outlook is not working, and I have no desire to continue with it. Will Thunderbird suit my needs? Will it allow me to import my old contacts and emails, both from my Windows machine and the new MacOutlook?

After Windows 11 crash and re-install and Thunderbird re-install, where can I find my old address file and old email file location in saved backed up data, and filename format to import in new Thunderbird installation? I have done this once a long time ago and forgot.

Hello Smart People:

I have literally decades of emails from a prior job that I want to detach from T-bird without deleting them. I hope to drastically reduce the size of "Local Folders" so I can more easily transport my email from machine to machine.

Archiving won't work in this case because it retains the mail, when I really want it removed, but accessible again later.

How can I do this?

Sincerely, Bob

Back when W110 went to w11 I got a new computer and was given great directions here to back up my TB profile by searching %appdata% and copy the thunderbird folder to external source. That file is 198 MB. I do this every month now ..It is my understanding it saves my profile and all emails including local ones. Now in Aug 2026 when i copy this file, I am getting an error a file is too long and have no choice but to skip that file..I will attach a pic of the error. Is this back up ok to use or is it corrupt because of the error?

I also found in TB help there is an export feature in TB to a zip file but that .zip is huge..I did one just in case. I think you just open TB>select hamburger menu three lines on top right>tools>export. I did that back up/export also today and that is a .zip file folder that is less properties like 175 MB.

So now which way is the correct way to keep a safe copy of my TB in case my computer crashes or i have to put on another pc?

Is it possible to import to, or display email messages, in Thunderbird, which are stored in a Becky Internet Mail program folder (https://www.rimarts.co.jp/becky.htm), please?

Thanks

Hi everyone,

I ran into a major accidental data loss issue in Thunderbird and I'm hoping someone can guide me on how to safely recover the messages.

What happened:

I attempted to copy a large batch of old emails from my Yahoo IMAP account into local folders.

Thunderbird initially moved them because I accidentally pressed "Move-to" Realizing they were moved instead of copied, I pressed Ctrl + Z to undo that action after all those emails were moved from my inbox to my local folder. That undo command synced back through IMAP and wiped those messages from both the local view and the server.

Those emails just disappeared and I want to get them back. It's been 6 days. How to recover them?

I am trying to migrate from Microsoft Outlook 2021 to Mozilla Thunderbird. I have successfully imported the email from a number of different email accounts. I would now like to import the archived emails held in a number of PST files. The import tool would seem to be what is required, but it does not seem to allow me to select the PST files that I wish to import. I am concerned that it will try to import all email messages from my Outlook 2021. Is there a way of restricting it to just individual PST files?

I was attempting to use Thunderbird Restore Tool to merge multiple Thunderbird profiles. Before I started, I copied the existing Thunderbird profile to a safe location where it has remained undisturbed. The Thunderbird Restore Tool did not produce the desired results, but that is a story for another day. I tried copying the saved profile back to C:\User\Tom Hayden\AppData\Roaming\Thunderbird\Profiles. I then started Thunderbird. It returned something very close to "Your profile file is inaccessible or corrupted". After some research, I edited the profiles.ini to point to the old profile file. Thunderbird would not start. I tried multiple iterations of thunderbird - p to run the profile manager. I was, eventually, able to get thunderbird to start and read the most recent e-mails from the server. However, it would not load any of the old e-mails from the old profile. I went to the profile thunderbird is currently using. Under ...\thunderbird\profile\pd785tbj.Default_User\Mail I found Local Folders-1 and pop3.airmail.net. Under pop3.airmail.net I can see the directory structure I used for my old e-mail. Everything appears to be present and in place. No matter what I do, Thunderbird will not read/load those e-mails. There is also an ImapMail directory with mail.airmail.net. Under it is a directory structure that appears to be what is actually showing up in Thunderbird. How do I restore/reload/recover/whatever the old e-mails in pop3.airmail.net? Please make your answer as explicit as possible.
