All of a sudden I can't access my Thunderbird emails (since Sept 6). I dont remember my password and there is no message allowing me to change it. How would I access my email?

Urgent! I have just upgraded from Ubuntu 22.04 to 24.04. Now I can no longer start Thunderbird (there is no error message about this). I have read in various user forums that many other users are experiencing the same or similar problems. The problem is probably with Snap. As email is essential for me, please help me/us quickly. Thank you!

Current version 128.2.1 on Windows 11 and having and having a problem where all current emails with attachments are previewing to an much older email attachment. Tried re installing. This just started recently

Jeg har i adskillige år brugt Mozilla Thunderbird. Har ikke haft problemer før nu. Nu kan jeg pludselig slet ikke åbne den på min pc.( Windows). Fungerer fint på min mobil. (android). Får beskeden: Programmet kunne ikke starte, fordi side om side konfigurationen er forkert. Flere oplysninger i programmets hændelseslogfil eller ved at bruge kommandolinjeværktøjet sxstrace.exe.

Kan ikke se hændelseslogfil når jeg ikke kan åbne den. Kommandopromt siger: sxestrace.exe. ukendt

Hi there,

   In Thunderbird Nebula, version 128.2.1esr (64-bit). there is an orange "plus"sign icon when new mail comes in. Is there any way to modify it's behavior to show that I have read them? Currently as soon as I leave the Inbox to read something in another folder, when I return to the Inbox, the icon is gone. So, it's basically useless. Is it possible to change it's operation?

Thank You, Anthony Nethersole nethersole@mindspring.com

I need to talk or chat with someone who can walk me thru a solution. Your online helps are beyond my comprehension. When I try to send, or reply to, a message, I get a screen saying "Password required for outgoing (SMTP) server.twc.com." HELP!

I have been using TB (under Ubuntu) for years without problems. I am now on version 115.15.0. Suddenly today the performance of the UI is abysmal. Even selecting a different folder to view in the navigation pane can take over a minute to complete. The activity monitor is no help. It often shows that nothing is happening when I am waiting for the view to change from one folder to another. When it does show something, it is usually indexing an inbox, but I have 5 accounts with inboxes, so this is no help. How can I see which inbox is being indexed? Some posts say that there should be a pause button in the Activity Monitor for the indexing activity, but I don't see any such thing. Some posts recommend changing mailbox format from mbox to mdir, but they don't say how. Searches for "mdir" in Thunderbird's settings and in the support knowledge base support knowledge base came up empty. How can I restore Thunderbird's normal performance?

Thanks for listening: Last week, Thunderbird began returning this message with each attempt to send mail: An error occurred while sending mail. The mail server responded: <tedcomo@chartertn.net> sender rejected. Please verify that your email address is correct in your account settings and try again. I have no problem receiving mail. At the same time, my wife began having the same problem on her laptop, which tells me either Charter, or Mozilla, changed something. I started with Charter. They told me to rename both servers to mobile.charter.net (outgoing mail was formerly smpt.charter.net. No effect. They then had me log into Spectrum and send a test mail directly from my account. It went through OK and they said the problem had to be on Mozilla's end. Any suggestions?

Hello,

I can't receive new emails on my Thunderbird account because every time I try to refresh my inbox, I get this message:

‘An error has occurred while saving your messages. Make sure that the file system gives you write rights and that you have enough free disk space to copy the inbox’.

No problem with webmail.

We have another computer in the office connected to Thunderbird that receives all our emails. All the settings are the same, except that we haven't updated Thundebird.

We use a POP system.

Thank you for your feedback!

Hello, I used the Export command on my main Thunderbird installation. The file Thunderbird_profile_backup.zip is 449,5 Mb. When I try to import it on another computer running the same Linux Mint OS the Thunderbird package does not see the file.

My mistake, apologies, all good now.

Can you help please.

Thank you.

Hi. so microsoft has been SPAMMING and THREATENING me for months now that soon i won't be able to use microsoft accounts with "old" login. i guess they refer to app passwords. i just now updated thunderbird and it automatically changed all microsoft accounts to oauth2 and then it pops up a new window asking me to login.

so first time i logged into all of my microsoft accounts via thunderbird's pop-up window, it asked on every account if i want to allow thunderbird to do this and that, i clicked ALLOW. all seemed good, but then i restarted thunderbird and then it asked me to login AGAIN for all microsoft accounts. i manage over 20 accounts and this is seriously frikking annoying logging into all of them all the time. i have 2-way auth enabled with codes, so i have to keep copy-pasting those codes aswell.

why doesn't thunderbird remember the logins? even now as i'm writing this message, thunderbird popped up the login AGAIN, i didn't even restart it. wtf? why is it doing that? is there some setting or what is the issue here? why doesn't it remember the logins?

NOTE: i have custom windows 10, there MIGHT be some permission issues somewhere, but i have no idea where. thunderbird saves data just fine for other emails, such as gmail and yahoo for example. it's just microsoft accounts that no longer work. ALSO THEY USED TO WORK with app password, but on 16th this month microshit stops supporting "old" login methods, so they require oauth2 and thunderbird doesn't seem to be able to remember the logins.

can someone help? what is the issue? how to fix it? thanks.

I have an email contact who uses alias emails to include team members as CC. Such an alias can have the form

  !wawProdAIProjects@domainsample.com

However, the "!" in the local part seems to cause Thunderbird to modify the email address by adding double quotes around the local part:

  "!wawProdAIProjects"@domainsample.com

While both versions seem to be legitimate, my contact's incoming mail server considers the "modified" version with the double quotes as "undeliverable".

So now I am wondering if and how I can stop Thunderbird from adding those double quotes? Any ideas?

Thanks a lot!

Hello, I recently bought a MacBook Air 2024 with G3 chip (Sonoma 14.6.1) and used Time Machine to transfer all the data from my previous Apple MacBook Air from 2015 (Mojave 10.14.6) to the new computer. This also transferred my Thunderbird profile folder. It has the extension .default and an 8-digit combination of letters and numbers in front of it. Since the old version of Thunderbird no longer ran on Sonoma, I installed Thunderbird 115.15.0 and then opened Thunderbird on the new MacBook Air. Since then, Thunderbird has been taking an extremely long time to open (much longer than on the old MacBook Air with Mojave. Yesterday I updated to 128.2.0esr, which didn't help either. I deleted a deactivated extension in the add-ons, so that there are now no extensions, only a few dictionaries that I deleted as a test, which also did not bring any improvement. Switching off the hardware acceleration, clearing the cache and changing the themes did not improve the situation either. With the themes, I can only switch between dark, light and system theme - automatically. I checked and made sure that Thunderbird actually loads the .default profile folder from my old computer as the active profile. However, Thunderbird has also automatically set up a second profile with the extension .default-release. Could this be causing the problem? My active profile folder has a size of 15.21 GB and the new .deault-release profile folder has 18.6 MB. Both profile folders are located in Library/Thunderbird/Profiles I am quite desperate and hope that someone can help me. Thank you very much!

The global search in TB is completely defective. I am now running 128.2.0esr and hoped that update might fix it. It hasn't. I just wonder, are there any older or non ESR versions I can downgrade/move to, where the search is fully functional?

Have just had an issue with an email coming in from a support person at the Uni helpdesk. The inbox (see below left) shows the correct name and email address, but the content is quite different.

When I checked the mail using Outlook, the correct file content was shown (see below right).

I have tried compacting the Inbox folder within TB [128.2.0esr (64-bit)], but no change. I am running Win 11 (64-bit) 23H2 with the latest cumulative update (KB5043076) installed 5 days ago.

Any suggestions gratefully received!

Hello,

Even though [replied in another similar thread] that I have the same issue, I'm making another one 'cause it seems pretty dead.

Since ver 128 Nebula, some mails (sorted in a labeled folder) appear totally white / blank and I don't know why. They appear perfectly fine when viewed from my provider's webmail service (Gandi SOGo), but not in Thunderbird. But here's the thing: they appear fine from the sent folder after I replied to them (via the webmail).

I've already tried restarting in safe mode with all modules disabled, to no success.

Hi,

Mozilla Thunderbird graciously provides online calendars for holidays in different countries.

However, since last check (possible since a few days), there seems to be a configuration error:

https://www.thunderbird.net/media/caldata/DutchHolidays.ics redirects to: https://www.thunderbird.net/media/caldata/autogen/DutchHolidays.ics which redirects to: https://www.thunderbird.net/media/caldata/autogen/autogen/autogen/DutchHolidays.ics which redirects to: https://www.thunderbird.net/media/caldata/autogen/autogen/autogen/autogen/DutchHolidays.ics which redirects to: https://www.thunderbird.net/media/caldata/autogen/autogen/autogen/autogen/autogen/DutchHolidays.ics which redirects to: https://www.thunderbird.net/media/caldata/autogen/autogen/autogen/autogen/autogen/autogen/DutchHolidays.ics which redirects to ....

Well, you get the drift :)

Firefox is giving me a warning "The page isn’t redirecting properly. An error occurred during a connection to www.thunderbird.net. "

Please test yourself in Firefox. If the error is still there, please kindly forward it to the thunderbird.net webmaster. If the error is no longer there, it was fixed, and you can close this ticket.

Thanks again for providing this service, I'll look forward to continued use!
