Wenn ich Thunderbird öffne erscheint immer folgende Frage:

Geben Sie ihr Passwort für "pemuehle@bluewin.ch" auf imaps.bluewin.ch ein.

Wo finde ich dieses Passwort? Sonst kann ich Thunderbird nicht benutzen.

Hi, my Thunderbird calendar reminders are coming up 4 hours after the meeting.

Running Kubuntu. System locale/timezone OK, TBird set to use system time (though manually making it the same didn't help). HW Clock matches system time. Pacific/Auckland.

Tried exporting all my appointments and re-importing them - no change.

Sehr geehrte Damen und Herren, bei mir ist plötzlich folgendes Problem aufgetaucht: Nach dem Löschen einer mail wird diese nicht im Papierkorb abgelegt, sondern ist komplett verschwunden. Vielen Dank für Ihre Hilfe im Voraus. Walter Schott

Dear Sir or Madam, I've suddenly encountered the following problem: After deleting an email, it isn't moved to the trash folder, but has completely disappeared. Thank you in advance for your help. Walter Schott

Thunderbird says this "the certificate for imap.supanet.com does not come from a trusted source". however I have used this email for some time and am happy with it . can I continue with this certificate as I do trust this source

Suddenly TB stopped checking mail on time intervals set in the server settings. It does check mail at startup and when manually triggered. MacOs 15.7.3 MacBook pro M1

My ISP, Plusnet, has recently migrated stored email to a new organisation called Greenby. From the day that Greenby confirmed that the migration was complete, no new email has appeared in Thunderbird.

They said that there was nothing to do, although I had to confirm some credentials such as username and password.

Clearly, there was something to do! How can I restart the download of email from my new Greenby webmail account to Thunderbird?

So far I used MS Outlook for Calendar and Contacts as well beside to mail. How can I import Those data from Outlook and synchronise with my Samsung A53 mobile (Samsung calendar and contacts) without using MS cloud?

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

Since the most recent update, Thunderbird doesn't load the email when clicking on the entry in the inbox, and then when double clicking to open in a new tab, the main window is blank with a Loading... text on the top left, and the URL shown above starts with chrome://

Running Thunderbird 146.0

Since the last update to version 146.00, under the folder Archives, both the sub folders for 2024 and 2025 have changed to Drafts and I cannot change them back to show the year folder (2024 & 2025). None of my other yearly Archived sub-folders are affected from 2016 - 2023.

Under Properties, both show their respective year correctly - i.e. imap://wbriggs1%40sky.com@imap.mail.yahoo.com/Archive/2024 and; imap://wbriggs1%40sky.com@imap.mail.yahoo.com/Archive/2025

I attach screenshots showing the issue and any help would be appreciated.

In essence, after trying various ways of trying to sort the above out, it would be helpfull Mozilla if under the Folder Properties box, I could just change the name back from Drafts to the appropriate year. However, in the folder box when selecting the Name line, it won't allow you to alter the folder name. This would seem the simple solution to any alteration of Folders by being allowed to rename them back to the original name.

Is a problem about the last release updated or other? Please, write soon. Thanks Andrea

I had two emails on my Thunderbird. I deleted one by mistake. The G Mail account still works. I tried to reenter my Spectrum Account and I keep getting that my configuration user name or password are wrong. I checked all settings and they appear to be correct. I also deleted the account and tried reinstalling it and got the same result. I also tried to enter a new email account that I just got. I had the same result. Keeps asking me to reenter the password. (would be helpful if it would say why it is wrong (password, setting, etc.) I spent hours on this today. I worked with the Spectrum agent and we couldn't fix it. Bur it seems to be a general problem because I get the same result with both accounts.

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp-mail.outlook.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

Seem to get this (or similar) error frequently. It's like the things I set randomly revert or change. Have sent images of settings. I certainly don't know what to do.

I am using Version 146.0, released December 9, 2025, on a Win 11 Pro, v. 25H2 pc. No problems until today. Messages won't download from two AT&T (ameritech.net) accounts. T-bird is not asking for mail key. No change after restarting T-bird; same result after rebooting pc. How do I restore email access? Thanks.

I had a scammer in my email. I've since taken the computer to a 'fixer' guy --and they got the intruder out. BUT my read emails are disappearing after a short time. Is there some setting that automatically deletes them? how can I find it and change it??
