Thunderbird コミュニティフォーラム

I have followed the instructions that several people give to transfer my existing Thunderbird installation to a new computer where I have just installed Thunderbird. That is I copied the Thunderbird folder and put it in the Roaming folded found in %appdata%. Both computers are on Windows 11. When I open the new Thunderbird, it does not recognise it. Furthermore, in Help>Troubleshooting information>Profile folder when I click to open the folder, it looks for a folder that is not in my previous Thunderbird installation: qr19mupe.default-release instead of the one that came with my imported Thunderbird folder. Has this happened to anybody and found the solution? Can anybody help please?

Hi, Need help with maps that cannot be removed. Thunderbird downloaded my map configuration, after a new Thunderbird installation, from my online account/my internet provider which was OK. After that I removed all maps on my online account but the maps in Thunderbird is still there but out grayed and I cannot delete them?

I uninstalled Thunderbird and also removed Thunderbird associated maps under %AppData% and %LocalAppData% but when I do a new clean installation same maps shows up in Thunderbird again? I waited some days and did a new installation again, but same issue. I have also deleted everything in W11 cash memory.

Attached picture shows the out grayed "NyMapp and subfolders" I cannot delete. How do I get rid of those folders?

Any help is appreciated.

Bonjour, Je vous promets que je vous fais un don dès que vous aurez mis fin à votre publicité mensongère à propos des Dossier récents : ils ne sont jamais triés par ordre alphabétique, quelque soit le paramétrage demandé.

Thank you for the advice on copying the Thunderbird folder, which I have done. However, what is failing is the adding of further existing email accounts. I enter the Account name, the email address and the password but I still get Authentication error. I have, after some difficulty, succeeded in adding five accounts with three different hosts. The further accounts I wish to add use two of the hosts of the successful additions.

Hello Folks,

We are a team of around 15 users who have been using Mozilla Thunderbird with Google IMAP for the last few years. Until recently, Thunderbird has been working reliably without any major issues.

However, for approximately the last one week, we have been facing a serious performance issue with incoming emails. Around 12 out of 15 users are experiencing the same problem.

The main issues we are facing are:

Newly received emails take a very long time to download. After clicking on a newly received email, it takes a considerable amount of time to open and display the content. Emails appear to be downloading extremely slowly, even though our internet connection is a 100 Mbps ILL (Internet Leased Line). The issue is affecting multiple users simultaneously, so it does not appear to be limited to a particular user's Thunderbird profile or PC. We have already tried Repair Folder / Repair Inbox, but the issue persists. We are using Google's IMAP servers for our email accounts.

We are currently using Mozilla Thunderbird 153.0.3 (64-bit) – Meadow Badge.

Could this be a known issue or bug in the latest Thunderbird 153.0.3 update, particularly with Google IMAP?

We would appreciate any guidance from the Thunderbird community/support team on how to troubleshoot and resolve this issue. If there are any recommended settings, logs, diagnostics, or Thunderbird configuration changes that we should check, please let us know.

Since this issue is affecting 12 out of 15 users, it is becoming a significant operational problem for our team.

Any help or suggestions would be highly appreciated.

Thank you.

メールソフトをアウトルックからサンダーバードへ移行したく、サンダーバードのアプリはダウンロードしましたが、 サインインに失敗なのか？認証できなく困っています。受信サーバーはIMAPですが、サンダーバード ではPOP3とでてきたので、手動でIMAPにかえてもみましたが、とにかく認証しないのです。 どうしたらよいか教えていただきたいです。

I have a new PC. I have added five email accounts, three different hosts, with some difficulty. Thunderbird finds the details for others but then refuses with the message Authentication error. Unable to log in at server. Probably wrong configuration, username or password.

I added Thunderbird by copying from my old PC. The hosts for those not yet added are the same as those added.

Been using Thunderbird for a number of years but recently the SSD on my laptop became corrupted and I had to buy a new one and install TB and restore my profiles from a backup.

I have two accounts and switch between them with Profile Manager.

The new laptop is an ASUS Vivobook with Win 11 Home and although TB runs ok the first time, if I close the current session and try to open the other account, nothing happens when I click on TB icon on the taskbar. IF I wait for around 5 minutes then it will run

Checked in Task Manager and cant see any instances of TB running, so any thoughts on what's wrong. Does not matter which order I open the accounts.

My Mac last night lost thunderbird (and numerous others things) and it's setting itself up again. I get an error that smpt already exists and I can't go any further! What's going on? Using Comcast Mail.

The method I formally used (Ctrl+) to increase text font size is no long working nor is Ctrl with mouse scrolling, nor is any other options I've found in settings. The font size on header and side bars is increasing but not the text of emails.

Hi I tried to google this but as you can guess that was a exercise in futility.

So I installed thunderbird via flatpac as suggested by the main website

I went to account add a account entered my email and password.

Clicked continue twice setup filled in the info and got a error saying

Authentication error.

Unable to log in at server. Probably wrong configuration, username or password.

now i know both are correct as i logged in vai firefox and checked both excepted.

pic below best i can do dam thing wont let me set window size so it got cropped hopefully gives info needed

so I tried to google the settings of incoming and outgoing 4 out of 5 pages i found where set as the pc has set it.

at a loss now guys no clue what to do any help would be appreciated.

ty in advance.

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.

Each time I open TBird, I get a message at the bottom left of the screen telling me that TBird has deleted X number of messages. I do not want TBird to ever delete any messages. How do I turn this automatic delete function off?

When I am on my thunderbird email page and switch to page where I used to find my address book. Now all I see is an option to create a new address book. What happened to my old address book? screen shot.HEIC. screen shot.HEIC.pdf

How do I fix this Sending of message failed. An error occurred while sending mail. Th mail server responded Policy -MFRM53 Relay Denied-unauthoruzed. Please verify that your email address is correct in your account settings and try again What should I do

Your last update included a Yahoo signup splash screen. Please remove it in the next update. It is annoying and does not serve any purpose other than ccnect me to Yahoo web mail. If I wanted to use that service, I sign in for it. I am content with using Thunderbird. Or at least give me the option of removing it myself. Thanks.
