Thunderbird E-Mail stürzte beim Öffnen ab, es wird lediglich eine graue Box angezeigt, mit einer statischen Internetadresse (in roter Schrift). Kann man auch nicht anklicken oder so. Ich hatte wichtige Kalenderdaten auf meinem Laptop, die ich nun nicht mehr abrufen kann. Kann ich irgendwie wieder an die Daten herankommen? Danke für die Antworten.

Thunderbird 128.3.3esr 1) Hotmail required authentication to be changed to OAuth2. Despite doing this I still get Authentication failures in the same Thunderbird session although closing and reopening the Account Settings shows authentication as OAuth2.

2) Once Thunderbird is closed and re-opened the Account Settings shows authentication has reverted to normal password.

3) I've tried deleting the account. It reappears on next load of Thunderbird even when I've also deleted pop-mail.outlook.com from the profile (There is only one and it is the default). The pop-mail.outlook.com entry also reappears.

I'm considering deleting Thunderbird and attempting to reinstall (I know enough to be able to preserve what mail I want) but if that fails to solve the problem I suppose I'll have to give up on Thunderbird and find another mail client.

I've used Thunderbird for many years and occasionally contributed to Mozilla's requests for a contribution but until this is resolved I shall continue to ignore Mozilla's persistent and annoying request for a contribution. After all - even if I were to contribute could I be sure that request wouldn't continue?

Hi there, I had chatgpt help me write my message because I was big mad about e-mail not working. The below is my actual concern but summarized much more nicely than I could ever write it.

I am writing to seek assistance with an ongoing issue I have been experiencing while using Thunderbird as my email client.

I have a self-signed certificate for my email server, and I frequently encounter problems with Thunderbird not being able to retrieve my emails. It seems that every once in a while, Thunderbird refuses to accept the certificate, prompting me to remove and re-add my email account entirely. I have tried manually removing the certificate and re-adding it; however, Thunderbird consistently reports that it is a valid certificate.

When I remove and re-add my account, I am prompted again to accept a security exception, which I do, and then my email retrieval works correctly. My concern is: why do I have to constantly add exceptions, and why does email not work if Thunderbird reports the certificate is valid?

Additionally, I am having issues with notifications. Specifically, I would like to know how to prevent Thunderbird from showing notifications through my OS notification bar. Recently, I received a notification about being unable to connect, but it was cut off, leaving me unaware of the full message and details. It is quite frustrating, as it shouldn’t be this complicated to manage an email client in 2024.

For your reference, I am using Pop!_OS 22.04, which is based on Ubuntu. My current version of Thunderbird is 128.3.3esr(64-bit).

Thank you for your time and assistance. I look forward to your guidance on these issues.

Best regards,

I have back up the gmail and my gmail account has been suspended. After that i have import my gmail(mbox) into the thunderbird but unable to see my gmail.

Could you please urgently let me me know what is the cause of this issue?

Since migrating Thunderbird to a new computer and updating to version 115.10.1 every word I type into a new email is marked as misspelled.

It says that its using the English (United Kingdom) dictionary but reports words such as "I" "The" "and" as incorrect.

I could always turn spell checking off but I'd like to fix it....

Any solutions?

I am not very tech savvy, so I apologise if I have asked this question before.

Having just downloaded Thunderbird and trying to add email addresses I keep getting a pop-up asking for passsword. I have tried every password I have with no success.

The pop-up says: Password Required - Mozilla Thunderbird.

Having never, to my knowledge, created a password for Thunderbird, I am stumped.

Any suggestions much appreciated.

Hi,

I haven't changed anything within Thunderbirds and sent email just yesterday on it. Today I tried to reply to an email and got the following message:

"The mail server responded: From address must match authenticated address. Please verify that your email address is correct in your account settings and try again."

As I said, nothings been changed and everything looks okay.

I am not very techy, so would appreciate any help on how to fix this issue.

Thanks,

Stuart

Since 2 days I can't send Mails

If I press Send the Menu & Buttons became disabled and the Mails are not sending. I can interrupt and it is asking me if I want to save the Mail I remember that it was an Update of Thunderbird (128.3.3esr 64Bit), since then I've this Problem. I tried to disable Antivirus, but no success. I've an older Version of Thunderbird (115.16.2) installed on an old server, an here everything is ok

Whats could be the Problem ?

Hi, the subject line says it all about my query but for some context, I need to know how many events there are for a specific calendar in a 180 day date range. I can't see any way of making this calculation. Currently I am exporting the calendar to an HTML page and entering the approriate dates into an online tool. Does anyone know Lightning intimately enough to have a more elegant solution?

Cheers

I have been having problems with Thunderbird ever since I updated from Windows 7 to Widows 10 about 6 weeks ago. But these problems have become overwhelming recently. I have latest version of Thunderbird 128.3.2esr (64 bit). An unusual aspect of my setup is that I do not keep my Thunderbird profile on my C Drive but on another drive. I need to keep many of my emails so I have a large Archives with the emails kept by each year. I also have a large number of emails in Local folders from a previous email software I was using. Over the last few days I deleted a large number of emails from these Archive files to try to reduce the size of them. I also deleted a lot of emails from my current Inbox (as well as moving emails from there to Archives). But my Thunderbird has started to play up in ways I cannot understand: 1. Thunderbird has created about 10 new folders with names like Inbox-1, Inbox-2, Inbox.msf-1.compact-backup, etc. There is even a folder called Trash-1 2. Inbox-3 has one message in it which is one line of garbage - but the size of the folder is reported as 3.8GB! Inbox.msf-1.compact-backup has 1 message in it which is full of garbage and is reported as 6.1MB 3. My Deleted box got large in the process of doing the above. So I have emptied it several times. But the size of the Deleted box keep growing and has now reached 102 GB! I have compacted the Deleted Box and it does nothing. 4. Multiple copies of some of my emails are turning up in my Inbox - some as many as 6 or 7 copies. As a result the size of my Inbox keeps growing. I tried using a Thunderbird Extension that removes duplicates but, although it correctly identified all the duplicates, it stopped functioning when I clicked OK to remove the duplicates. 5. Needless to say that Thunderbird also at times excruciatingly slow and frequently freezes (with "(Not responding) showing on the Thunderbird window. 6. At one stage there were 1000s of message which were dated 1/1/1970 and were blank. I think I have deleted most of those. Using Windows Task Manager, I can see that CPU and Memory usage are always blow 50%. The Disk that the Thunderbird profile is on is sometimes at 100% and sometimes at a low %. But this does not seem to correlate with what I am actually doing. For example right now as I am typing this message, it is showing 100% active time and disk transfer rate of 450kb/sec but I am not doing anything with Thunderbird and the Thunderbird Activity Manager is showing no activity. But another time I could be trying to delete or move emails and it shows a low % of active time on that disk. I have looked through this support site and tried the following suggestion: I have put the Thunderbird profile in the exceptions section of my Antivirus software I have deleted global-messages-db.sqlite and allowed Thunderbird to rebuild indexes I have disabled all extensions as well as the extension I mention above for removing duplicates. I tried opening Thunderbird in Troubleshoot Mode and Windows in Safe Mode. Thunderbird operated more quickly but the problems did not resolve. Bewildering? I have been using Thunderbird for 10 years but after 6 weeks or so of problems and many frustrating hours, I am looking around for alternative email software but I don't want to go to Outlook. Does anyone have any suggestions for email software that can deal with large Archives?

I can't send e-mail to anyone. When i send out, it won't work and it appear like gray screen (normally, it appear send , copy e-mail and successfully sent)

Please help me to resolve this problem. I have tried every way that I can do.

I've managed to set things up where I can receive email, but I don't seem to be able to send it. None of the help files seem to be pointing me in the right direction and it's getting to be a bit frustrating. Any ideas what I can do - it's only the outgoing server settings that seem to be the problem.

Hello Dear Thunderbird and Lightning Community!

Microsoft is removing their local Outlook calendar from Windows OS at the end of this year, and have already started to remove the direct to accessing it through their regular updates.

As I am looking for a local, reliable Calendar that would be on top of that open source, I found out Lightning as a further add-on/extension to Thunderbird.

Given the general context I have mentioned in the beginning, this is an historical opportunity for the open source community to raise Lightning as a major alternative to Outlook Calendar (and not only Thunderbird globally).

Why not offering Ligthning also, as a pure STANDALONE, local (with online calendar for people who wish it), but at east as a local possibility without NEEDING to instal Thunderbird as a whole?

That would make a lot of sense.

Thank you very much and great Kudos for all your great work!!!

Cheers :)

Hello, I am replacing the Outlook integrated local calendar on Windows 10 with Lightning, given the fact that Microsoft has decided to remove it from their OS.

I just came across two webinars invites that only propose VCS files (and not ics files) for adding the event in my local Lightning calendar.

As this was not working when I clicked on the invite to directly add it to Lightning I made some research and found out that there is the following Add-on for Thunderbird Lightning: https://addons.thunderbird.net/en-us/thunderbird/addon/vcs-support/

However the last update for this add-on is dating back 2011 and the last comment is from 2015...

In terms of security I am not sure that I want to install this add-on and I am not even sure that it is working.

Could the Thunderbird Lightning Developers maybe add the native functionality of accepting these files for setting events in the Lightning calendar?

Thank you very much and great work this community is doing!

I use Thunderbird 128.2.0esr (64-bit) to read mail from the Outlook server; these are the folder mappings:

imap://<email>@outlook.office365.com/INBOX imap://<email>@outlook.office365.com/Sent imap://<email>@outlook.office365.com/Drafts imap://<email>@outlook.office365.com/Trash

I used to also be able to read the Junk Email folder from the Ourlook server the same way, but the folder disappeared from my Thunderbird a couple of months ago. I tried re-adding it as a sub-folder, which is how I created it in the first place, but it won't appear on the list.

I'm not sure what else to do here. I don't know where the Thunderbird directories are stored locally any more, I'm using Ubintu 24.04.

Hi, A few weeks ago, my desktop PC had to be returned to the manufacturer for repair, so I had to move my email to my laptop. I have 9 email accounts (3x yahoo, 3 x Microsoft, 2 x GMX and a Gmail). I used to train adults how to use a computer or laptop (basic training) so had addresses for different providers, so I was familiar with anything they could throw at me! Some don't get a lot of use now, but I like to keep them, for the odd occasion. All the accounts loaded sweetly at the time, some requiring 2FA, but none needing any App Passwords. A week ago My laptop had a catastrophic problem requiring me to restore to factory defaults. Since then, I have been reinstalling all the programs/apps to get it something like it was before the disaster occurred. Obviously, as part of the process, I had to reinstall Thunderbird. However, I have not been able to get any of the accounts to get set up on Thunderbird. The settings are found in the database and passed as okay, but I've been getting messages like: "Unable to login at server. Probably wrong configuration, username or password." I know the settings are correct because I have double-checked them very carefully, and I also use Bitwarden to ensure the Username and Password are correct. Initially I had wondered whether it was just one account that was a problem, and had tried other (alternative and approved) port and security settings but got a "Thunderbird failed to find the settings for your email account" message. I am puzzled, because about 3 weeks ago everything went in so easily, and I completed all nine accounts one after the other in probably less than half an hour, and now I can't complete any. I'm obviously playing with the idea of trying another email program, but also liked the calendar in Thunderbird. I'll attach some screen prints below. I also use Nord VPN, but for a fortnight it didn't matter whether Nord VPN was on or off, Thunderbird was brilliant. Today I was wondering whether that was having an effect, so I switched on Split Tunnelling, and applied Thunderbird, but it made no difference. So my next thought was whether as part of the Factory reset of the Laptop, not all the registry entries for Thunderbird had been cleared, or that there was some files somewhere that had escaped the purge and Thunderbird was still pointing to them. However, that didn't make sense, because I had Uninstalled Thunderbird with BC Uninstaller and deleted entries found after uninstallation, before I reinstalled it. So what can I do other than find some other email product, which seems unlikely at present! Kind regards.

Since about two weeks the perfomance of Thunderbird is much slowed by regular appearing of the words "Does not react". This can occur at any time - when writing, when opening an attachment... If I wait long enough (sometimes minutes) it functions normal again, but can fall back in the same error at any time. Is this due to the continuous updates of Microsoft? An overworking of an anti-virusprogram? When I check "help" I use the latest and updated version of Thunderbird. Any suggestions?

On MacOS using the OS dark theme selection, and the Mozilla TB neutral (default) System theme, Thunderbird forces all reply message backgrounds to be black. Emails are sent with black text over black background This can only be corrected by turning off the OS theme. (An app theme is supposed to theme the app, not the content.)

So TB is forcing Mac users to use an OS theme not of their choosing or to send unreadable emails.

• MacOS Sonoma 14.1
• Thunderbird 128.2.3esr
• System theme — auto v1.3 (latest)

Text and Background Settings:

• Text: [black]
• Background: [white]

Extensions (all latest versions):

• No Message Pane Sort
• quickFilters
• Restart Button
• uBlock Origin
• Xpunge

A very experienced and qualified computer technician has already experimented with all conceivable combinations of authentication options, port numbers and server names, as well as different email clients. The problem still has not been resolved. Michael Hobbs
