TB has been working for years with 2 gmail IMAP accounts and Google calendar. TB has just updated to 91.8 and the gmails and calendar stopped working. I deleted the stored passwords, started TB in troubleshooter mode and re-entered the google passwords.

Google calendar is now working but the 2 gmail accounts still don't work.

I deleted one of the accounts from TB and re created from scratch. Account creation fails with

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

The other gmail account which I haven't deleted comes up with an authorisation error after entering the google password and allowing access.

I have checked that TB cookies are allowed and javascript is enabled.

I have run out of things to try.

What I don't understand is the calendar is working but gmail isn't even though they use the same Google account and password (and Oauth2).

I am using the latest Thunderbird 91.8.0.8126 and latest Firefox 99.0.1.8136. I am having the same issue as reported in these posts:

https://support.mozilla.org/en-US/questions/1343530 https://support.mozilla.org/en-US/questions/1344530 https://support.mozilla.org/en-US/questions/1350244.

I have 5 Gmail accounts that I manage for different family members. All accounts in Thunderbird access Gmail via IMAP, and are configured to login with OAuth2.

This week, Google removed Thunderbird access from 2 of the accounts, I do not know why. When I login to the accounts via the web in Firefox, Thunderbird was no longer listed under their 3rd party access. The other 3 accounts are fine.

1 of the accounts does not have 2FA enabled. I was able to re-login with Thunderbird when prompted, and I was presented with a window to grant Thunderbird access, which worked, no problem. So Thunderbird's browser was clearly recognized.

But the other account does have 2FA enabled, and that is where the problem lies. Thunderbird prompts for login, and the username and password are accepted, but when I enter the 2FA verification code, Thunderbird presents a window saying "Your browser is not supported anymore. Please update to a more recent one." (https://bugzilla.mozilla.org/show_bug.cgi?id=1677845). There is no option presented to grant access to Thunderbird. Yet, the verification did work, because my primary email receives notification that the account was logged in from a new device.

For the record, the failing 2FA account is managed by Family Link (the other non-2FA account is not). According to https://support.google.com/mail/thread/127545584/, such accounts cannot login to email clients. But that has never been a problem before, and 1 of the other still-working accounts in Thunderbird is also managed by Family Link and works just fine, so that can't be the culprit.

Also, I do have AVG installed with Email Shield enabled, but disabling that makes no difference.

Thunderbird's UserAgent is "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:91.0) Gecko/20100101 Thunderbird/91.8.0". And yes, cookies are enabled in both Thunderbird and Firefox.

Is there a way to get Thunderbird to use Firefox properly for Gmail login, instead of its own integrated browser?

I have 2 installs of Thunderbird on 2 different desktops accessing the same IMAP account.

On one machine I have:

  Automatically delete junk mail older than 3 days

On the other it is:

  Automatically delete junk mail is unselected.

Which has priority?

I am seeing junk mail from over 30 days in there so I'm guessing that if one installation does not automatically delete junk mail, then none of them do. Does the longest duration take precedence?

Thanks

I keep getting a prompt from Windows Defender regarding a security threat from my email : C:\Users\MYUSERNAME\AppData\Roaming\Thunderbird\Profiles\3a9dgcsq.default-release\ImapMail\MYDOMAIN\INBOX->(part0131:Shipping_Documents.docx)

I chose Windows Defender to remove this threat, but nothing happens. I have tried to search for the file name, and also tried to look into my inbox, even deleting mail in the inbox with attachments. I then cleared the log of Windows Defender, but this threat still shows up.

I am unable to locate this file. Please advise as I am desperate.

Thanks!

New issue after Thunderbird update 91.8.1., running MAC OS-X 10.13.6 High Sierra. My IMAP inbox stopped getting messages and just hangs. When I click Get Messages I get the spinning blue wheel. Down at the bottom of the window it says that it's connected to the imap server but nothing happens except the spinning wheel. The POP accounts are working fine. I checked with the domain host and nothing has changed on their end. I've had to resort to webmail for this account which is problematic. Any suggestions and solutions are appreciated. Please help! Thanks

Hello, I have a GMail account, from which I download my email in Thunderbird (in Linux), and keep it ordered locally.

I noticed that my backups are very slow, because Thunderbird keeps two big directories that get updated often:

11G /username/.thunderbird/k0aa999s.default/ImapMail 7.0G /username/.thunderbird/k0aa999s.default/Mail

under /username/.thunderbird/k0aa999s.default/Mail I see I have my local folder structure and that's good, but what is under ImapMail ? I guess it is the corresponding email structure I have on the gmail server, (although gmail reports that I'm using 5.67GB, not 11GB). The 11GB are created by just 4 files: 1.6G Apr 22 09:55 Sent Mail 3.0G Apr 22 14:16 Trash 2.6G Apr 22 14:16 Important 4.3G Apr 22 14:20 All Mail

I saw it suggested to rebuild the folders in Thunderbird - I did it but nothing changed

What can I do? I dont need / want to replicate Gmail structure locally, I just want (and use) only what I have under /username/.thunderbird/k0aa999s.default/Mail

My problem is not a serious kind of stopping me work problem, just an annoying one. Almost every time I start Thunderbird from scratch at start up I get the message "Thunderbird has stopped working". But the annoying thing is that it has NOT stopped working and never does, I can simply delete the message and carry on just fine. I have never had any further problem!!! So, my question is how to stop the message pop up? I am working on a reasonably powerful quad core PC with adequate RAM running Windows 7 Pro. The only problem I have had lately is Firefox! After lots of quirky problems and trying lots to fix it I finally gave up and changed to Chrome!!!

I have just bought a new PC and installed Windows 11. I have imported all the IMAP setting and all folders and emails have downloaded to Tunderbird but when I try to send an email, I press Send, the send button greys out the email remains on screen and does not send.

Mail Provider: Fastmail Firewall: Windows Defender Anitvirus: None OS: Windows 11 Thunderbird version: 91.7.0 (64-bit)

Server name: smtp.fastmail.com Port 465 Authentication method: Normal password Connection Security: SSL/TLS

in Thunderbird I have several email accounts like [edited] @cox.com and [edited] @yahoo.net. on only one of these accounts all of the information is in frames. The other accounts work fine. BUT in one of the accounts all information appears in windows frames. How can I remove these red frames from all of my e mails in this one account?

/edited emails from public forum.

I saw someone else who also had Windows 7 like I do ask about this error message, and the only answer was "Update Thunderbird." Just like me, he had Thunderbird 3.1.4. There was no follow up saying it worked.

Will the current version of Thunderbird *run* under Win 7? Or not? Updating my OS on my primary PC is not an option. 98% of Thunderbird works just fine, the only issue I have is that I can't download images in emails. I'm afraid to upgrade, and break Thunderbird.

"If it ain't broke, don't fix it."

Yes, I have a Win 10 laptop, but it's too inconvenient to use it most of the time, so it stays in the box until I have something I *have* to use it for. That does not include daily email.

I receive messages from the Guardian newspaper and LinkedIn and the hyperlinks do not work. I went to safe mode and still the same.

The bar at the top is green, when I click on a hyperlink it changes to a light grey. Firefox is set as my preferred browser.

Help or a solution would be very welcome.

Regards

I have setup my business office mail address with the owl extension. When I try to send an e-mail a error message pops up that Thunderbird couldn't put a copy into the sent folder. So I wanted to place the copy only in the local sent folder, but the settings is grayed out and I can't change anything.

When I look at my personal microsoft mail with @outlook.de I can change everything and the setting is picked correctly out of the box

Thunderbird v. 91.8.1 MacOSX Monterey 12.3.1 I keep getting this error message. "Unable to connect to your IMAP server. You may have exceeded the maximum number of connections to this server. If so use the Advanced IMAP Server Settings dialog to reduce the number of cached connections" I have reduce the connections in 'Advanced' Server settings' to 1 but the problem persists. Can you advise please? Regards, Philip Bergman

thunderbird 91.9.1 in Win 10 Uninstall & reinstall I have a issue with in-coming emails, as they load they go from BOLD to marked as read. I have tried everything I can think of. If I delete Thunderbird (using windows "Uninstall") and install a fresh copy will my setting stay? Barry

When switching on Thunderbird 91.8.1 (64bit) today, it immediately downloaded mail from my IMAP account followed by the message "Server not found - start.thunderbird.net could not be found. Please check the name and try again. Check typing errors / network connection / firewall / proxy etc." Selecting 'Try again' simply opened the 'Welcome' overlay leaving the client operating as before.

This is a first as far as I can remember. But in the midst of the other more problematical events that have been occurring, (see my previous question, recently updated discussing possible Settings errors retained in the Profile): 'Exporting folders with ImportExportTools NG' https://support.mozilla.org/en-US/questions/1373167

Can anyone suggest if there is any link between these events - and confirm a solution that would clean or replace the profile but leave (or restore) the messages and folders unchanged ?

Hello,

I use Thunderbird for all my email addresses, have for years. Never had an issue until today. I've been offline all weekend and have not received an email to any of my addresses since 04/29, 3 days ago. Is Thunderbird down? If not, how can I fix this?

Thank you

I'm setting up a new PC, and am using the same settings that have been on the old PC for three years and are in the Yahoo configuration guide: Pop3 inbound. att.net/outbound. att.net 995/465 SSL/TLS Normal Password

I've been at this for hours, and Tbird just won't connect. The error is "Unable to log in at server. Probably wrong configuration, username or password". I am stumped.

I temporarily logged into customer email account in order to download the mail in it and transfer it to their email at a different webhost.

And in fact subsequent to that the email account was closed at the prior host by its owner. They actually deleted the email account at the old host "Bluehost" which admittedly is a garbage host and hence why they moved.

So I removed it from my email accounts in my Thunderbird.

For some reason since then I have been receiving constant popups from Thunderbird "Authentication Required - Mozilla Thunderbird - https://box2164.bluehost.com:2080 is requesting your username and password. The site says: “Horde DAV Server”"

and the username field has the email address in it. The password field is blank.

And I checked the outgoing mail servers in Thunderbird to confirm I have no connection to the email acct stored in Thunderbird.

Any thoughts on how to alleviate this issue?

Thank you all for your time and attention to this request.

I used to send a group from my address book with 15 addresses in it.

Now I get this message "Sending of the message failed. An error occurred while sending mail. The mail server responded: mL0anej4od7RfmL0bnCIXh internal error. AUP#SMTP. Please check the message recipient "kissrockssoo@shaw.ca" and try again."

I broke the group into two groups one with 8 and one with seven. I can send to each group individually so I do not understand why the larger group won't go.

Were limits put on at your end?
