Thunderbird Community Forum

Emails that arrive while my PC is shut down do not appear even after I start the PC and launch the app. There are no error messages. The server is configured to use POP.

Last week my Inbox started showing TWO (2) unread messages, but I cannot find any unread messages in my Inbox. My SPAM folder is also showing two (2) spam messages, but there is only one spam message in the folder.

With the latest update, this very annoying THREADS appeared, and I cannot go back to the original format for individual emails in their correct chronological order. I do not like this format, and if I can't go back to the original, then I will be finding an alternative email program - that is how annoying this change has been to me.

Hello. How to display categories in messages (applied in Thunderbird for Windows) ? On Thunderbird for windows messages are displayed withe the color of the category. Best regards.

Since the latest update, the uploading of new emails from the server can take minutes to hours. I know the emails are on the server, because I can see them by logging onto my email client on my iPad. Why has Thunderbird suddenly become very frustrating to use? An example which just happened - I was required to enter a 6 digit code to be able to confirm my account before I could submit this question. I waited, and waited and waited to see this code in my Inbox. Finally I went to my iPad to get the code, so I could submit this question. It was there as I expected, but not in my Thunderbird Inbox for another 10 minutes. This is happening far too often, so I am contemplating finding another email program which is not so frustrating.

Hello!

I am using Thunderbird 140.9.1esr (64-bit) on a Ubuntu 24.04 system. Every time I restart Thunderbird, it reverts to a little used Gmail account as the default account. I have several accounts, but my main email account is a MS365 account. I reset the setting, but every time it is restarted, the default goes back to Gmail. I have tried everything that I've found online, but cannot correct this behaviour.

Do you have any suggestions or assistance?

Many thanks!

All of a sudden my comcast.net email is no longer accessible through Thunderbird,it claims I'm not using the correct password, even though none of the settings have changed. I can still access my email through webmail, using the same password. What's happened? and how can it be corrected thank you

I installed Thunderbird on a new computer running Windows 11. I use Thunderbird for 14 email accounts. I have set the folder view to "Unified Folders." In the Inbox, emails from different accounts appear twice—sometimes they do, sometimes they don't. These emails are not duplicates; in the folders for each individual account, the emails are all displayed only once. I don't have this problem on my old computer—same Windows, same Thunderbird, looks exactly the same. Does anyone have any idea what might be causing this?

I have the latest Thunderbird update. Since yesterday, using imap.comcast.net, I have been getting the error "Login to server imap.comcast.net with username [removed] failed." It wants me to retry or enter a new password. I cannot get emails. I can, however, log into my Comcast email account online and see emails delivered. Thunderbird, of course, will not receive these emails.

For imap.comcast.net, port is 993, connection security is SSL/TLS, and authentication method is normal password. I have not changed any of these settings. I have not changed my password. I have done nothing to cause the problem.

I cannot find a solution online. Could someone help? Thank you!

Good day, thank you in advance for your help.

I have two questions: 1. Do you find Thunderbird release [version number missing] better than ESR? Could you share your opinion?

It seems faster and applies all changes more quickly.

I will test it sometime if 32-bit and 64-bit versions are available simultaneously. I have no idea what kind of channel that would be.

Problem/Question:

In Thunderbird release 64-bit POP3, the font changes to blue for every second email (receipts). Can you tell me how to display every email in black? It's only the second email in the inbox that's displayed in blue (receiving emails). When composing, everything looks black. What do I need to change?

Question 2: Regardless of whether it's 32-bit or 64-bit, and whatever channel, I see updates to the latest version. The program itself has an option to view older updates, but everything is white. I only see white and nothing else. Is this intentional? I can't see the update, even though it's current?

``` thanks for the information

All emails in my trash folder disappeared. I do not know if this is due to something I did, or some other reason. Is there any way to restore the deleted emails?

As so many have experienced, but I have yet to find the actual solution, I will bring up the issue.

I recently purchased a new computer. Installed Thunderbird, created all the mail accounts I have and... no problems. All the accounts, once created, populated with emails. For 3-4 days, there were no issues.

Important to note: I let TB use all the default settings. And once everything was up and running >>>>I did not change anything<<<<<.

Then a few days later, I started getting the following messages for two accounts that had migrated from q.com to myctl.net. Entering the 100% proven-correct password results in the know endless-loop of entering the password and the same pop-up error message. The PW is 100% correct as I can go to Centurylinks' website and login using that same, exact password and read my emails.

I've spent enough time trying all the suggestions here, reddit, facebook etc so I'd thought I'd see if anyone has actually found a solution.

Bonjour,

Depuis plusieurs semaine ce problème survient.

"Le certificat pour imap.gmail.com:993 ne provient pas d’une source sûre".

Ce problème, uniquement sur l'ordinateur avec windows 11. Sur le GSM pas de problèmes.

D'avance merci pour votre réponse. Cl. BERNARD

I didn't knowingly make any changes in Thunderbird, but my Sent folder says there are 2,669 messages in the folder, but displays an envelope and No message found. I upgraded to the latest version. How do I fix this?

(I haven't had time to move all functions to another drive.)
