Hi. I love Thunderbird! But I cannot use a Gmail account.

It all started when I changed the underlying password for my Gmail account (for routine security). I changed the password too on my Thunderbird client for SMTP and IMAP.

But then it popped up with: https://accounts.google.com/v3/signin/identifier?app_domain=http://localhost& [etc]

it keeps giving me this message:

"400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

I've tried to read online what's going on. I've deleted the account and tried to set up again, and closed Thunderbird. It keeps doing this. I've checked Google settings ... nothing untoward. It doesn't have a link to Thunderbird still.

What can I do?

Thanks, Dan

I am moving my email hosting from one hosting account to another. I have both accounts configured in Thunderbird. The original account has many many folders and sub-folders. How can I copy the structure and all the contained emails to the new account?

Hi folks. I got a popup today advising me to upgrade Thunderbird to the newest version. I thought, "hey why not, I've been using Thunderbird for YEARS, I like it it's great"....so I did I can no longer connect either of my gmail accounts or my icloud account. Is this a known problem with the upgrade? If I wait a bit will "it fix itself"?

Any ideas?

Thanks!

When I try using the box to align fields (First Name, Last Name, etc.) I get a couple of lines to match up and then after that as I continue they all start to float around. What is the method for setting the left side with the right side of the box? I'm importing my address box from Gmail.

Hello,

So, my company want to trash their Exchange server for Gmail accounts. Welp, OK... but Thunderbird (last version) doesn't cooperate.

I tried to add a new account with the correct information. I set the IMAP/SMTP of Google as this is an other domain, SSL connection and OAUTH2 on both servers as needed. The Google window appeared, login and password is fine, I clicked on Authorize.

But Thunderbird doesn't want to create the account because of a sudden login/password issue.

The login/password is fine, I tried it on the browser and I did succeed the OAUTH2 process so this is not the issue. The Google account states that Thunderbird is indeed authorized.

Cookies are authorized.

I tried to change the password for something more stupid.

Heck, I even recreated a new profile without changing anything. In desperation, I even tried using the standard password method after activating the Less Secure Application in the Google account.

Thunderbird still refuses to connect to this account, with the same login/password error.

I don't get it.

Does someone have a solution before I shoot this retarded bird ?

Cordialy,

I guess this could be considered "migration"... How can I sync the email between different machines, as & when I switch to use of a different installation of Thunderbird?

Here's my current setup: I have 2 laptops, and each is set up as a dual-boot with both Windows 10 Pro, and AntiX Linux. That makes a total of 4 operating systems, and I have Thunderbird installed on all 4.

I'm not sure how useful this is, for framing an answer to my question re. syncing, but here's extra info: I keep all my personal data on encrypted external hard drives, which I access using VeraCrypt. External is so I never lose my data if a given machine dies. Encrypted is so, even if the physical external hard drive is stolen, they can't steal the personal data. (I maintain a cloned backup external drive.) Today, I chose a location on the primary external hard drive, and created a folder named "Thunderbird email". I'm using the AntiX v19.4 OS right now, so I've set that new folder as the Local Folders location within this installation of Thunderbird.

I got this far, and then realized I need some guidance from more experienced users. So, I located this support page, and signed up for asking my questions about Thunderbird. Thanks in advance, for any help you can give me.

Hi,

I've recently upgraded to the 91 version and the order of the account folders have changed. i.e. the email folders and the off-line personal folders are no longer in their previous order. How would I change the order.

I tried moving them, but they return to their original position after every reboot of thunderbird 91.

Additionally, is there any good docs about folder paths to learn more about archiving or default settings.

Thanks,

I'm trying to help an elderly friend move from Eudora OSE to Thunderbird. I found this closed thread on the forum - and I want to know 'how to back up the Eudora OSE Profile' - or any other help you can give re migrating from Eudora OSE to Thunderbird. (She has thousands of old emails.)

The tech person said,

"May I suggest, back up your OSE Profile, and give it a try.

And the other replied: "I took the tech's suggestion Backed up Euroda files and simply installed Thunderbird VOILA ! When I launched Thunderbird it simply accessed the same files and file structure (and settinge/etc) as Eudora and I didn't have to do anything ... awesome !"

I have re-installed Windows 10, and Thunderbird. My address book information and messages are missing. Can these be found somewhere and saved.

thanks

Every morning when I open Thunderbird I receive the notice that "Thunderbird can't update to the latest version." but I am already running the latest version (91.9.0 as of this writing, screen capture attached).

None of the following have worked to resolve this issue yet:

• Download and install from "Download Thunderbird" link in notice.
• Uninstall and re-install from fresh download.

Any thoughts what I'm doing wrong, or what else I can try?

Thank you.

Mbox upload to thunderbird went smooth. Setting on 14,000 emails in Local folders... However when I drag and drop that folder into the inbox of my gmail account so I can view remotely on any device, It caps out at 2500. I searched this on the web and it looks like google caps imap exchanges to 2,500/day but it says that it allows you to migrate entire inboxes up to 3 a month...

How do I get more than 2500 or set a schedule of uploading in the right order for exactly 2,500/day?

OR is there a better way altogether to get this to happen? I tried to connect my gsuite email account to pull in all old files but it could never gain access which led me down this google takeout mbox down load and upload into thunderbird

I have a Windows 11 original OS on my PC computer. I can install Thunderbird and it recognises my MS Hotmail Account and sets it up as normal. When I attempt to set up my gmail account I get the following error message: "Unable to log in at server. Probable wrong configuration, username or password." As far as I can tell all the details are correct. Anyone able to give me an idea how to get this working.

Hi,

I had to update from an older version of TB to the latest due to the gmail security changes. I had an security/authentication issue that was brilliantly solved by a contributor here.

I have now realised that the update caused another problem ... my address book is empty. I have been doing much searching and reading about this and it seems that the problem is that there was a failure to convert the old .mab address file to the new .sqlite address file that the newer TB version uses. What I could not really find is the definitive answer.

I do not have any .mab.bak files in my profile folder. I have:

• abook.mab(44KB and filled with addresses)
• abook.sqlite (256KB and filled with zeros)
• history.mab (77KB and filled with addresses)
• history.sqlite (256KB and filled with zeros)

From what I read, the option open to me is to downgrade TB (all the others appear to rely on the .mab.bak files), export the address book, upgrade TB again and then import the exported address book. What I'm hoping is that someone here know a simpler way in which I can get the new TB to convert or "see" the old .mab file.

Many thanks.

I have used Eudora for years, about 20 or more. Now I find myself with a dilemma. A secure email program I signed up for must have ports assigned to incoming and outgoing servers. Alas, not possible with Eudora, but possible with Thunderbird.

However, after reading several of the threads of migrating to Thunderbird from Eudora, it appears to be problematic--new addons, missing mailboxes, etc. It's hard to tell whether that's the norm or the exception. One of the threads I read was https://support.mozilla.org/en-US/questions/1228297 "Migrate Eudora mail to Thunderbird mail", which suggests starting with Thunderbird 17.0. That thread is from 3-1/2 years ago. Is this still the best way to migrate? Or is one of the Thunderbird migration tools a better and safer option.

I have literally thousands of saved emails and dozens of separate mailboxes and I don't want to lose them.

I bought a new laptop because the old one died. Now I tried to transfer my TB data into the new computer. I managed to do it BUT... only one of my two MAIN folder data is there.

Last time I needed to do that when my laptop died it worked. Now despite me using the EXACT profile path/name (eg, C:\Users\XXX\AppData\Roaming\Thunderbird\Profiles\XXX) in TB's local directory at my new computer only one MAIN folder's data is present.

Does anyone know how to solve this issue?

Thank you!

I have set up a new server for all my web sites, including the domain I use for e-mails. I have changed the nameservers and e-mails are going to the mailbox on the new server. The e-mail address remains unchanged. I now want to set up an account on TB to access these e-mails. I've gone through the 'Add Mail Account' procedure, to the point where TB tells me 'incoming server already exists' and I can get no further. Do I need to delete the old account in TB and start again? I can do this, of course, but it means setting up a whole lot of preferences over again, which I'm hoping ot avoid.

I have been using Outlook for my email accounts, including Gmail, but would like to install Thunderbird as Gmail soon will no longer work with my version of Outlook. In the Mozilla support article "How to add your Gmail account to Thunderbird", it says that after configuring the account, "Thunderbird will download your existing messages and your Gmail will be ready to use." Will Thunderbird at that stage download every message in Gmail's inbox? My problem is that I have thousands of old messages in Gmail as have never accessed Gmail from my browser but from my email programs (Outlook Express, Win Liive Mail, Outlook) where I store messages in folders and delete whatever is not needed. If Thunderbird is, by default, going to download everything in Gmail, are there any options to limit this by date or any other criteria. Thank you for any help. Scotch

Copying the .thunderbird directory from old computer onto new computer no longer works.

Following instruction here: https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer is not possible because nothing happens when I click at this point: "On your destination computer Locate the "Profile Folder" entry, then click Open Directory."

Thunderbird is a Flatpak 91.9.1 (64-bit) Thunderbird-flatpak - 1.0 on Fedora-36.

Many years ago, I had two computers receiving email. Both received a copy of each email.

I am attempting a move from my old Thunderbird (38.5.0 in Windows XP) to a new 98.9.1 in Linux Cinnamon Mint. I sent an email to the mailbox. It was received only by the new Tb. I shut down Tb and restarted it. I sent a second email. It was received only by my old Tb.

The server settings are: Check at startup, Check every 10 minutes, Automatically download, Leave messages on server, Until I delete them."

I can find no option to allow the email to be downloaded by two Linux versions of Thunderbird, though surely that must be routine for those who receive their email both on a computer and phone. I need a POP solution, since I can be away from either version of Tb for some time.

Help, please!
