Thunderbird Community Forum

Dear Community I have had an gmail account on thunderbird for years. In/outbox etc details were still on thunderbird but when checking account details in Thunderbird all info was there as normal.... but.. in "View password"..there was no details at all for this gmail account - but were there for other accounts.

Went to the gmail app and tried login...my email and password are correct...login was ok. I deleted the gmail account from thunderbird and tried to to do "New, Email Account." and entered my gmail account details correctly and hit Done when green gmail 'configuration" is "found".

Then I get a google window to sign into my gmail email account - it has correct email address shown.. I enter correct password and get this message.

"400 Thats an error... The server cannot process the request because its malformed. It should not be retried. Thats all we know"

Thunderbird email setup then shows a yellow box that says "wrong configuration... etc"

Checked in gmail settings and imap is ticked - pop is not. Also checked Gmail "Connections to third party apps and services" and Thunderbird was enabled in April 2021.

Does someone have a fix for this?? or... where have I gone wrong?? Cheers M.

Already a voluntary donor and satisfied Thunderbird user then I suddenly lost many of my folders and could not recover them, asked for support but got none; nobody interested! As a non-techy older person I expect help when necessary so this has been a sobering event, making me question my continued presence here; very disappointed. John

Thunderbird is so slow, especially when deleting emails. This has been happening for a month or so. It got better last week, it seemed normal, but it's back to being infuriatingly slow to delete messages. My workflow is very disrupted. Any solutions? I need my time back!

Dear Sir or Madam,

I'm using Thunderbird already for a long time and I'm very happy about it. Until now!

Since 1-2 weeks the programme does not download my emails anymore. I have to go to my hosting company and download my emails from my various domains, which is a pain. I read your "solution" in the help section, but it does not help as yet. I don't know what I might have done to change the settings, but when clicking on "Get Messages" no text at the bottom bar apears that it is looking for mail, but only a blue coloured bar at the right bottom on my screen apears and when completed disappears again. When I then go to my host company (Dot5Hosting) I can find my new emails.

What do I need to do to solve this problem? Thank you very much in advance for your solution(s). Kind regards, Ronald Verwer.

Hello, about maybe 2 months ago I noticed that TB display random subfolders without any clicking on main folder. I have plenty of folders and subfolders and on left side in window with folders and subfolders sometimes but very often are displayed subfolders of - sometimes one and sometimes more folders. This happen without any click on main folder. Because my folder tree is pretty long this cause that folder that I need for my work is suddenly out of my desktop and I need to scroll to see it. Or I have to click on each displayed folder to hide subfolders. Is there any chance to avoid this kind of behavior. Thanks. Peter

Hi.

Why every time i run thunderbird and if i leave it open too often it bring me the error message for all hotmail/outlook mail accounts i have???

What the heck is happening and how i can solve this?

I just sent a message in community forum (I think it was) about how some of my messages were loaded as raw html code, tonight. Well, I just found an interesting temporary fix: I send the offending message to "junk", then say it isn't junk, and send it back to my inbox: then it displays as it should. I tried to edit my original message here on Thunderbird with this new "fix", but was unable to. And it still doesn't solve why messages in my inbox load this way to begin with; but I thought it was interesting as a diagnostic feature.

I am still wondering whether to reinstall Thunderbird...

This has nothing to do with virus scans, because I don't have any going 24/7, that I'm aware of. Maybe Windows, though-- I'm never quite sure what it is doing. But no other 3rd party virus scans. Thanks.

Some of my emails tonight are displaying as raw html code. That is, I just get code-- no message. Really annoying! I saw another comment on here that suggested one needed to repair folder; it seems to me I'm always repairing my inbox (because I thought perhaps I wasn't receiving all my messages, but the problem may have been from the sender). I don't have any paid virus scan regularly scanning my PC-- except maybe Windows Defender, or whatever it's called these days? I am using Win 11. But I don't think I have any viruses, either. I often run Win Defender or free Malwarebytes-- but not whilst receiving email. I have never had a virus that I'm aware of. The problem just started. Should I re-install Thunderbird? Thx,

I'm getting these notifications multiple times a day. It serves no useful purpose, there is no way to stop them, that I can see and no way to universally shut off this type of notification. Please help!

Why is my program stuck on "send later"? I see no way to change it to "send". How do I get thunderbird to send a message, not "send later" with no indication of how or when to send it?

I've had this problem for about a month now. The last few thunderbird updates have been performing very slow on my system. I frequently get the 'wait or force quit' dialog popups when trying to use thunderbird. When viewing emails with HTML content, it often has long pauses where nothing happens and the UI is unresponsible.

I do have multiple email accounts, a lot of email (multiple folders with 20K+), and irc open. CPU and memory utilization are fairly low on the PC. It's a desktop with a 11900k + 32GB RAM + nvme m.2 pcie gen 3 ssd + intel arc a750.

I'm noticing issues on wired (via powerline) or wireless (802.11ax)

I have a client that has three laptops running Windows 11 and the latest build of Thunderbird. She has the same three email addresses (MSN.com, outlook.com and gmail.com) added to TB on all three computers. When sending a test message to one of the email addresses they arrive in the inbox on just two of the computers and not on the third one. All three email accounts have identical POP/SMTP settings and "Leave mail on server" is checked. Any ideas as to why just one of the computers would not receive inbound email messages? When I added the account to the computer in question, there were no error messages, and the account addition was successful. Any thoughts as to what might cause this?

I have a folder that indicates there are 13 messages in the folder, but only displays 4 of them. How can I recover the other 9 e-mails in the folder to be able to view them?

My message filters do not run. They appear to be properly set up. They don't work, even when I select "Run Filters on Folder", under the Tools Menu.

Here are my Filter Rules for one of them:

• Apply filter when: Manually Run (checked) Getting New Mail: Filter before Junk Classification (also checked)
• Match "Any of the following"
• From Is (sender's email address)
• Perform these actions: Move Message To (Junk on my email address)

I am using Thunderbird version 128.1esr (64 bit), Thunderbird Windows MSIX package, Thunderbird-MSIX-10 My system is Windows 11 Home version 23H2

Thank you!

Hi, I've tried searching for this but there seems to be alot of misunderstanding as to what is being asked, so please forgive the length of this post. Running Windows 7, Thunderbird 115.15.0 (64-bit). On opening Thunderbird or when a reminder point for a calendar or event is due a Reminders Window Pops Up showing all reminders/events. I can dismiss individulally or All or snooze indivulally or All. There is also an option [X] to close the window. Q, As to my actual question, if that window is closed, for what ever reason, I can not find away of re-opening the window, any help on how to do this? Please note I am not referring to the "Today Pain" which I can show or hide as needed. As an example I may have an appointment due on the 12th of the month, but need to prepare for it so I set a reminder for 3 days before, ie 9th. So on the 9th a reminder for the appointment appears allowing me to dismiss or snooze. I would commonly start to prepare and as such leave the reminder as is, not clicking dismiss or snooze but closing the window. Later on in the day I wish to open the window so I can clear the reminder. That's the window I wish to open and do not know how. Snoozing will not help as I may not be able to predict how long it takes me to prepare and therefore can snoze for too long or too short. I've included a screen shot of the actual window in question with a dummy reminder. Hope this was too long and thanks for any help offered.

Ubuntu 24.04, Thunderbird 128.1.0esr (64-bit)

I have a mix of POP and IMAP accounts. All are read when starting Thunderbird, I receive the messages. But then, only the IMAP accounts get the messages, whatever the configuration of the Server Settings. I.e. no messages for the POP accounts from "Check for new messages every X minutes", nor from "Get Messages". I have to restart Thunderbird to get the new messages for the POP accounts.

Everything worked well before, this problem happens since I have upgraded Xubuntu from 22.04 to 24.04, where the Thunderbird package switched to a mandatory Snap, where it upgraded to 128.1.0.

I am unable to add a subfolder in Thunderbird, delete a folder, or rename them. I am able to copy a folder to another account.

I right-click on a folder, select "add subfolder" and nothing happens, the same when I right-click "rename" or "delete". I just started using the dark mode theme and relaxed density. When I switch back to defaults settings, I still have the same issue.

Thank you!

I have multiple email accounts configured in Thunderbird, all of them are IMAP and hosted through Google/gmail.

Occasionally emails that I delete or move to folders will return to my inbox. This happens very irregularly. Sometimes it happens daily, sometimes it can go many days without an occurrence.

If emails are sorted within the gmail browser interface, the problem never happens.

I've tried a complete deletion of Thunderbird and all app data, and resetting all email accounts but the problem persists.

Thanks in advance!

Any way to insert a dividing line in list of messages like was in Seamonkey (or Netscape?) so can separate batch(s) of emails downloaded til I can look through them so they can be easily grouped/found?
