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

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?

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,

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!

i cannot import vcards created in outlook 10 into tb address book. cant import single, group or all in single file. cant import windows or outlook contacts file either. using tb 115.15.

help please.

Good day

I hope you are well. I'm not sure if it's a bug or a problem but here is my problem. My settings are configured such that my sent emails are moved to the folder from where I'm replaying. Now and then the email I just send does not show the content of the email and also does not show anything in the subject or from who it is. The content of the email is random letters and symbols, maybe it shows only the encrypted email for some reason. This problem can not be a device problem because my college ran into the same problem. If I go on my phone (Gmail app) the email in question appears as normal there but not on my Thunderbird app on my laptop. The same problem also appeared from an email received from someone but only happened once or twice.

Please can you assist in solving this problem?

I am unable to attach/send files through other programs or windows - instead of Thunderbird the program will try to use Outlook.

Thunderbird is set as the default map in MAILTO in Windows settings.

This worked fine until recently - I think a windows or Office 365 update may have overriden something, but I cannot find any settings to change to attach and send through Thunderbird.

Any help or advice would be much appreciated

I have a problem with opening messages in the thunderbil program, I keep getting the same error, I downloaded updates, but it didn't help

I have just raise a question here - missing folders after xubuntu upgrade, but I accidentally put "xubuntu 22.04" in the headline instead of 24.4. Can't find my way back to edit the question. Profuse apologies.

I tried changing the authentication method to OAUTH2 for my Outlook live mail account (POP). For that, I had to change the server name to office365.com. After restarting Thunderbird, I was able to download new messages but all the old messages already stored in Thunderbird disappeared, even though Thunderbird still shows the same old Local Directory as being used.

How do I change the authentication to OAUTH2 & get my old messages back?

If I delete & again create the Outlook live account, would it effect my old mails/filters ?

My default browser (Edge) starts when Thunderbird opens requesting a donation. VERY time I start my TBird, the ad pops up again, completely taking over my computer. What needs to be done to prevent Edge opening when TBird opens?

I am makinmg some changes to the accounts on Thunderbird.

When I add an account all goes well until I close Thunderbird. When re-opening the account is not there.

When I delete an account all goes well until I close Thunderbird. When re-opening the account is still there.

Other than that all is working well.

Thunderbird keeps demanding re-enter password after password has been entered and then checked and re-entered multiple times. won't respond to most in put. The problem showed up before my computer was up-graded from windows 10 to Windows 11 a day or so ago.

I'm receiving e-mail at infinity's web-sight but not on my computer.

Hi, We do have some problem upon mail synchronization between CPanale mail ( my mail server) with Thunder bird ( on my laptop). We have found that when we access my mail server ( CPanal ) directly and   delete some mail, that mail ( In my Thunder Bird mail box - upon my Laptop) will be automatically removed from my Thunder Bird mail on my Laptop. I want to delete file from mail server without any automatically synchronize delete file in my Thunder bird. How can i set up Thunder bird?

For five months now I have received 50-70 spam emails a day. I have no password to change in Thunderbird, but should I encrypt or something to get out from under this? They do go to Junk, but still . .

I was sorry to see that the 128 Nebula release did not fix the longstanding problem that Thunderbird is very slow to load in Sonoma, and has been since the Sonoma release. This is with 128.0.1esr (64-bit) on an Apple M1 Mac Mini with Sonoma 14.6. I have the same problem on a 2018 Mac Book Pro running Sonoma with an Intel chip. The problem is NOT manifest on a 2013 Mac Book Pro running the last release of Big Sur. In all 3 cases the same email accounts are loaded, so it is some interaction with the OS. (I previously reported this for Tbird 115 under Sonoma, with no resolution.)

Specifically, when I start Tbird 128 on the Sonoma M1 the window comes up in about 2 seconds but contents are blank. The contents don't fill until about 30 seconds. This makes it painful to quickly hop into email to do something, so I am resorting to Apple Mail when in a hurry. If I do the same on my 2013 Big Sur machine, it's 2 seconds for the window to come up and 8 seconds for the content to fill. Upgrading from 115 to 128 did not change this on any of the machines.

None of the enhancements of recent releases are of sufficient value to compensate for this, so I wish the team would focus on ensuring speed on all platforms. Is there any clue what is going on?
