Thunderbird Support Forum

With the latest update 115.11.0 the existing profile was not identified and loaded. All existing configurations, mail and address book are not accessible. The likely problem is the installer program that uses IP address as a factor in finding the correct Thunderbird account. I use VPN and do not have a static IP address. I have been shut down for several days now and any attempt on my part to resolve the issue has failed. The old email is very significant. Unannounced updates can cause serious trauma for Thunderbird users.

I just purchased a Google Pixel 8a, and needed to install the reader for my Yahoo Mail account. When I searched for Thunderbird for Android, I found Edison Mail+. How does that fit, or is this something I don't want?

Is there - yet - a Thunderbird for Android? If not what do you recommend? I had been using K-9 mail on my Pixel 6a (which, I had understood, was the forerunner of Thunderbird for Android), but it just doesn't want to install on the 8a.

Hi!

Trying to use Thunderbird to connect to my hotmail account but get an error message that says I can't log into "server" due to the prefs or login details are wrong. Have tried to search around for answers but can't see that anything is wrong. Any idea what to do? Use windows 10 professional.

Thunderbird is not downloading. Email email or feeds. It is. Not downloaded since May 11th. Also your website is i Inaccessible Through any of the browsers, please help.

I recently un-installed an old version of Thunderbird that was showing a vulnerabilty and would not patch itself to the latest version for some reason (old version was in the 60s). I had all mail stored in a non-standard folder on my D drive so that it would be included with my backups. After uninstalling, my non-standard folder is still there. However, the location where Thunderbird was originally installed was removed and that is not included in my backups.

I installed today the newest version of Thunderbird, but I cannot get it to open my old mail. I'm able to login to my accounts, but I need to access the email stored in my non-standard storage file.

I have downloaded the addon cardbook. Now, how do i find my old address books that existed prior to the addon? Please do not leave a single step out on how to migrate back or forward or what ever i have to do to get my old tb moved to the new cardbook tb supernova. Thank you.

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

Upgraded to Sonoma 14.5 on iMac and when trying to open Thunderbird, I get the message "Thunderbird" is damaged and can't be opened. You should move it to the Trash. What do I do?

I'm moving from win 10 to 11 in new PC. I downloaded Thunderbird. I have hidden files showing in new PC so I found where it should be. When I look for the Thunderbird I downloaded it's not there in roaming...so I can't move my profile into the new computer. I have it on a drive read to install, but it's not showing up.

I am moving Thunderbird to a new PC, old was Win 10, new is Win 11. I installed Thunderbird on the new one, same version 115.10.2 though this is now 64 bit, old was 32 bit. I followed the instructions to move the profile by copying the Thunderbird folder onto aUSB stick then copying it to the new computer. The address book is there, but the local folders I had are not. Looking inFile explorer, I see that the Local Folders folder is there which contains all the folders I had, all populated, but there is also a Local Folders-1 there which does not, and this is the one Thunderbird is using. If I delete this folder, next time I start Thunderbird, it creates this folder again. I have obviously done something wrong, but cannot see what it is.

I have a Thunderbird on my old windows computer. I just installed it on my new computer (and I donated). I could have sworn that I had the import/export tool on the old Thunderbird. I desperately need to move some folders of emails from the old computer to the new one. I can't find a way to do that. I went to a link that said the import/export tool no longer works. I tried archiving the messages in a folder but have no idea where they went. Luckily I could undo that. What is the best way to move these folders of emails to the new computer? It was really easy many years ago.

i have 2 computers running the latest thunderbird 115.10.1 (64-bit) one is in perfect layout exactly the way i want it the other has more layout issues than i have time to fix to make it back the way i want ( a fresh install ) i just want to copy the lay out not the accounts , not anything else is there a file or 2 i can just copy and put on the new computer ? and make thunderbird look normal

I am setting up a new Windows 11 Computer and am trying to install Thunderbird. I have downloaded TB (Thunderbird Setup 115.10.2) to my Download Folder. I double click on that file to run the Setup program, complete the user account information and TB and select Continue. TB completes the search and displays the correct account (att.net) connection information, SMP, POP3, Ports, etc. I select DONE and the Checking Password box displays. It runs for a few minutes and an Error message displays: "Unable to log in at server. Probably wrong configuration, user name or password." If I select Configure Manually, a window displays showing the correct configuration information (I have checked it four times). I will note that "Normal Password" has been selected for Authentication Method in case that is important. I have tried this method several times and get the same Error message. Any help will be greatly appreciated. Thank you.

I have attached a screenshot of the configuration window. Note: My account is with att.net but I am still using my old pacbell.net account that was merged with ATT many years ago.

My wife got a new computer and I'm transferring her folders from her old windows 10 computer to her new Windows 11 computer. I have Thunderbird installed on the new computer with her account. Thunderbird on the Win10 comp is 32 bit and the Win11 comp is 64 bit. Both are the same version (115.10.02). On the old computer, in the MAIL folder there is "inbound.att.net" which has her mail files (Inbox, Sent, Drafts, etc.). Should I just copy all the files inside the "inbound.att.net" folder to the new computer?

Is there anything else I need to copy and paste from the old TB to the new TB folder? I'm guess that I will have to at lease copy and paste the abook.sqlite file from the old to the new. Any other folders or files.

Maybe I'm doing this wrong and there is an easier way to do this? I've read the article about moving data on the TB Support page but it doesn't mention anything about TB data from a Win10 32 bit to a Win11 64 bit computer. Will the difference in Win10 OS and TB 32 bit and the Win11 OS and TB 64 bit, be an issue.

Thank you so much for the help.

Hi:

I'm a longtime ubuntu (lubuntu, actually) user, and upgrading LTS versions every 2 years has been pretty easy til now: all I had to do was copy my .thunderbird folder to the home directory of the new system.

When I do that now for the pre-release version of lubuntu 24.04,, the new Thunderbird requires setting up the new profile from scratch, which is a pain, since I use T-bird for multiple accounts.

Is there an easier way of migrating my emails from my old profile to the new system?

Thanks!

Bill
