I've just returned from a couple of months away, and want to access my emails on Thunderbird on my desktop. This is the message i get:

Login to server [...] with username [...] failed.

I've contacted my provider who say the issue is not with them but with Thunderbird. As I can access webmail ok I presume this is correct.

I have tried Troubleshoot mode, but that hasn't helped. And I've tried restarting the computer.

Any suggestions would be most gratefully received.

Thank you!

Is it possible to Move the email messages list to bottom right and have a preview of those messages in theupper right section? Thanks in advance for any advice. I have tried all layout options and can't seem to achieve that.

140.4.0esr (64-bit)

I have successfully moved over several email addresses and then the last one stumped me! I am receiving emails on that account but only 1 of the 9 folders came over. I have tried manually adding the folders but I get error messages from TB indicating that the outlook server cannot find the folders. There are old emails in those folders that I will eventually need migrated over. What am I missing?

Also, I am required to enter my password each time I open emails from the SmarterASP email server. That is going to get old. How can I stop this?

I was trying to delete many hundreds of old emails and highlighted many that were unread at a time. (Shift, select emails and shift on the last one). They highlighted in blue. When I clicked on "delete," the blue highlight turned gray and nothing happened. Now I can't even go back in and delete them one at a time.

Is there a limit to the number of emails I can delete in one group? How can I delete the ones that are now gray (instead of bold black showing unread)?

I hope this makes sense. Thank you for any assistance you can provide!

When I reinstalled Thunderbird, I got my account back, but the Local Folders were missing. I found where they're hiding on my computer, but I can't figure out how/where to copy and paste that folder so they show up in Thunderbird. Can someone walk me through those last steps, please?

Thanks

I can't access an MSN.com account, but I managed to do so with two other accounts. I've already deleted it twice and tried again, and the password is correct. Can you help me?

je n'arrive pas a accéder a un compte msn.com pourtant j'ai réussie avec 2 autre compte.j'ai deja supprimer 2 fois et réessayer et le mot de passe est correcte. pouvez vous m'aider ?

The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: [AUTH] Username and password not accepted.

This actually tells me nothing I can work with. Is this for the senders account (gmail).

I sporadically get messages through, but have to check in the gmail account as some do not go through.

How can this be fixed?

Hello everyone I'm running TB 128 on Linux Mint 21 and TB 140.3 on Windows 11 24H2. My email provider is Strato.de with IMAP. The problem is that TB doesn't allow unsubscribes from folders on either installation. So, if you select a server folder, the folder is displayed and the emails are included. I can unsubscribe from the subscription, and the folders are not gone. All folders and Mails are on TB.

With TB, all folders are loaded and all emails synchronized during installation and the first contact with the server. I can deselect folders in the "Subscribe" menu, but they are immediately available again. I can see in the TB status display that the unsubscriptions are being sent. Strato reports that their server is OK. It also works with Outlook 2013 in Windows 11 and two other email programs in Linux. It works well with other clients (Evolution, Balsa) under Linux. I can uncheck the folders from Server (Dialog in TB) and they're gone.

Today I also tested: 1. Live version Mint 22 TB 128 - same problem 2. Mint 21 TB version 115 - same problem 3. New mailbox/address created on Strato's server - same problem Can anyone explain this? Thanks. Holger

Sinds 15 of 16 oktober (nieuwe update?): Thunderbird programma werkt (bijna) goed. Mail opstellen werkt goed. Maar ..... er wordt geen mogelijkheid meer geboden om de opgestelde mail te verzenden!! Kan nergens op verzenden of iets dergelijks drukken. Wel werkt: vet-cursief, vergroten en verkleinen letter, smiley en meer zaken worden wel weergegeven maar spelling bijvoorbeeld weer niet. Hoe kan dit worden opgelost. Ik ben een echte digibeet! Thunderbird opnieuw downloaden en installeren durfde ik niet aan, bang om alle mail kwijt te raken.

Ik zit er goed mee om het hand. Ik hoop op spoedig oplossing.

Met vriendelijke groet;

With a recent update to Thunderbird I get repeated reminders for events (in a Gmail/Google calendar) that can't be dismissed.

The error states: "An error occurred when writing to the calendar d.......@gmail.com! Please see below for more information."

Details read as follows: "MODIFICATION_FAILED Status Code: 2,147,500,037, null Server Replied with 400 If you’re seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view."

They're thrown the next time I start Thunderbird, as well. What gives?

Please don't ask if I have permissions to my own Google calendar. I do. If I log into the same account on the Web, I can edit calendar events to my heart's content. I can change them, create them, delete them, etc. all I want.

I am also not going to set this calendar as read-only, as the Thunderbird error message instructs. That is not an option; it won't happen; and it's not even a solution.

Any other ideas are welcome. Thanks!

Can someone explain why the emails I write are still spell-checked, even though I have unchecked "Check spelling before sending message" and "Check spelling continuously" in "Settings" countless times? Even the Thunderbird add-on "Replywithheader" still checks spelling, even though I have unchecked "spell-check" there too. I don't want spell-checking, but I can't get away from it! It really bothers me.

When trying to add my outlook.com email account to Thunderbird 143.0.1, using the instructions at https://support.mozilla.org/en-US/kb/thunderbird-and-exchange, I get an "Exchange auth error." I'm able to add the account manually using imap, but I want to use Exchange so I can access my outlook.com calendar and contact when TB is updated to include them.

I have suddenly lost access to my emails on my desktop, though I can still access them on my tablet. When I open my emails, I get this message: The current operation on 'Inbox' did not succeed. The mail server for account jmquayle@protonmail.com responded: Mailbox INBOX does not

I can't see the rest of the massage.

How do I resolve this problem?

Hi, Just migrated off windows and onto Linux and I'm having a problem printing emails and attachments directly from Thunderbird. Printing from Mozilla itself works find. I have checked the config information and everything looks ok and when I go to print in Thunderbird, the printer is there but the information presented shows that Thunderbird has the printer greyed out. I have an Epson ET-8550 and the correct drivers are present but TB doesn't seem to finding them. I'm running TB v140.03.0esr 64 bit

I have several calendars on thunderbird, which use different colours for their events. This is great for disambiguation. (e.g. one calendar is for deadlines, another for normal events, one is for reminders, one for personal events, etc).

However, some events I want to appear as Free to others, and some I want to appear as Busy. While when creating the event, I am able to choose whether to appear as Free or Busy, there is no visual difference in the created events on the thunderbird calendar.

In other calendars (e.g. outlook), there is a visual difference, e.g. "solid" colour for busy, vs "striped" for free.

Is there a way to achieve this in thunderbird calendar? If not, please consider it as a future feature.

Best, T.

Hi,

Everytime I try to send an email it keeping buffering Copying message to sent folder, but does not do the same, but at the same time the recipient receives the email.

I checked my IMAP settings as well, and its perfect, infact was working perfectly alight all this time, until today.

Please help, its really frustrating seeing all the composed mails windows still open as the mails have not been copied yet to sent folder.

Cheers! Ali

i think pop3 might be the better option for me, its a big account with 4gb of emails and mainly just ones i want to back up and sort into folders. but i have a few questions first please?

1. roughly how long would something this size take to download? and if i deleted some spam in there first, then would it make it a quicker process? any sort of gauge of what to expect would help!

2. my internet connection and power source occasionally just fail without warning. If this happens during installation (likely if it takes many many hours) and before I have had chance to back anything up, what is the scenario? will TB just continue where it left off upon reboot? if it has failed and that process corrupted, would anything it had so far downloaded be lost? Would i need to remove account and start again, would i need to reinstall TB? and would those emails still be retrievable from the servers and a new attempt possible with a new account?

3. if I opt to 'leave on the server' for a few days, in case of the above, would they continue to be deleted after that time, even if the failed account was removed? would it be possible to try again with a new pop3 or imap account within this time? If all was ok, and backed up, then can i uncheck leave on and proceed to get them removed?

3. are subfolders within the inbox included in a pop3 account? or,after installation can i get the folders still on servers downloaded and backed up by adding to the inbox and opening on TB?

4. pop3 is often not recommended and Ive read that its more vulnerable to interception and less secure connection, is this true?

thanks for any help! (I posted all questions in one place to save multiple posts, but if its better to make a new question for each point i can do that!)

Hello,

Is there a way to instruct Thunderbird to ignore the HTTP response header “Last-Modified” when downloading an RSS feed?

Reason: When retrieving the feed https://www.verbrauchergesundheit.gv.at/aktuelle_meldungen/aktuelle_meldungen.html.rss https://www.verbrauchergesundheit.gv.at/aktuelle_meldungen/aktuelle_meldungen.html.rss the server sends “Last-Modified: Mon, 24 Feb 2025 12:38:15 GMT,” which causes Thunderbird to stop reloading the file after the initial retrieval of the feed.

Of course, I will ask the site operator to send a correct header. But if they don't, it would be nice to have an option in Thunderbird.

Thanks, Ulysses
