I have the Latest Thunderbird 115.10.2. I am running windows 11 pro 64-bit, 23H2 - OS build 22631.3447 I have run the latest downloads (KB5036980) My Mail server is run my Virgin Media. My email account Has 5 accounts, I seperately have an account with Fasthosts My wife has a gmail account and a company email for whom she works, So in total I have 8 seperate account from which I have set to download emails from. All my Thunderbird account ave been set up exatly the same with the exception of which servers they go to to down load emails. All accounts are required to automatically download every 4 mins, I have NOT ticked the - Leave meesages on server and both sub boxes - * so many days and - until i dele them all are unticked. The advanced box at the base of the Server Settings tab, is set to include this server (whiche ever of my accounts server it is) when downloading emails. My problem is that my web email for Virgin Media should receive all email for the 5 account I have with Virgin media. I have not set virgin media account to divert any emails. I was under the assumption that if Ive set up Thunderbird to download all my emails every 4 mins then nothing should be left on my web mail account, or so I thought. Due to my wife not receiving emails to her via 2 of her account, 1. Virgin media 2. her company email. So I wnet onto my web account with virgin media and to my horror i had 999+ in my inbox and had 500+ in the spam box. thinking this was the problem I set about deleting all the emails, 1st i emtied the spam folder in bulk delete. I then proceeded to delet one at a time just in cas i saw some that needed to be kept. The deleted email box hit 999+ minbox was still at 999+, cutting a long story shoert - I deleted of 8k emails, talk about sor index finger, and going cross eyed. My web mail inbox was now clear of emails, didnt last long, so by having my thunderbird open on one screen, I had the web maill account opebn on my 2nd screen. when email cam in some wer downloaded to thunderbird - some were not, even the ones that were down loaded stayed on the server and were not deleted. I checked every account in thyunderbird just to make sure i was not setting thing up correctly, I had. all the incomming mail has been for either me or my wife both accounts are with virgin media. Thunderbird downloaded only one of the emails to my inbox, it did not delet it from the webserver, no has the other 2 sent to me, the one for my wife, not her company email, is still stiing on the server and has not been downloaded. What is going on, its driving me crazy try to resolve a problem that I though I didn't have.

I have three different computers that I can use Thunderbird to access my hotmail account. All three computers can have the exact same server settings. One computer refuses to send emails unless I cancel the send and immediately resend.. Thunderbird ver 115.10.1 (64-bit) Windows 10 Home Ver 22H2 IMAP Mail Server outlook.office365.com Port 993 Connection Security SSL/TLS Authentication 0Auth2 Outgoing SMTP Server smtp.office365.com Port 587 Connection Security STARTTLS 0Auth2 Take Note All three machines can have identical settings listed above or various changes like Normal Password instead of 0Auth2 and/or an Outgoing server can be smtp-mail.outlook.com with normal password or 0Auth2... One computer must be cancelled will sending and when resent, it goes... no problem...immediately. If I don't cancel and wait, for it to send on the 1st attempt, it will eventually timeout on the outgoing server. Then I might have to reenter a password. Very annoying. I have been doing this for years. It is my workaround....

My internet provider in Phoenix, Cox, has now handed its email services over to Yahoo. Prior to this, I accessed my Cox email (@cox.net) using Thunderbird. I am a technological dinosaur and am trying to figure out how to migrate my new Yahoo email to Thunderbird. I had a friend set up my Cox mail in Thunderbird but he is not available now. I am clueless how migrate my Yahoo mail to Thunderbird. I appreciate any help that the community can give me.

Hi,

I created a backup of my Thunderbird profile including various email accounts and calendar. I used the build in export function of Thunderbird to create this backup. Unfortunately the file is slightly bigger than 2GB.

I had a severe copmputer crash now and I wanted to import the backup. It turns out that the zip-achive is damaged. I cannot unpack it with any zip-software and also repairing the archive with winrar did not work.

Is there any chance that I can at least restore some of the information?

Best, Robert

Hi, Excuse my poor English (I am French). Linux Mint 21.3 Cinnamon (64), Thunderbird 115.9.0 (64) no added module - Installation from the Mint list of software. My problem : regardless of the provider (Proton, Gmail, Outlook, GMX - in IMAP), the message menu bar (see <https://support.mozilla.org/fr/kb/personnaliser-la-liste-des -messages#thunderbird:linux:tb115>) does not appear. How to make it reappear ? I think I have tried all the configuration menus and possible right clicks within Thunderbird ; I haven't found anything on the Net ; starting in safe mode did not change anything. I come from Windows 10 where I didn't have this problem. Thanks in advance for your help

Hello, For some reason, over the past couple of months I have been searching for varied emails and they are missing! At one point, I found that some had been put in an archive folder (that I did NOT set up) and they were recent emails. I removed them from the folder, placed them back in the regular inbox and deleted that folder. When I could not find another very important series of emails today, after searching numerous ways, I looked in the server and missing emails are there. I did look at a number of email threads where other people reported similar problems... but couldn't figure out what applied to my situation and how to fix this. To show a specific example, I attached two images ... the first is my Thunderbird email account that shows one Email only on Feb 18, 2024. The Juno server image shows 7 emails on that same date, four which were important contracts that were sent to me. Can you please help me locate and retrieve these and other missing emails? Thank you very much. Ms Randy Rosette

Hello,

I'm using Thunderbird for my private and company e-mails (different companies). I need to pay close attention to selecting the right names as the auto suggest for recipients isn't using the context of the current account. Is there a plugin or setting I've missed that considers the context of composing a mail and priorities collected e-mails from the respective account or recent conversations for example? Good example is the Gmail auto complete, that has a good suggestion ranking.

Best I could find was options to sync with Google Mail contacts, but that would require to maintain a list of contacts in Google Mail, which I don't do.

je n'arrive pas à envoyer des mails avec ma messagerie sur Thunderbird, mais j'en reçois. L'icone en forme de cadenas est barré de rouge, cela m'affiche qu'il y a un problème avec le chiffrement des messages. Puis, que la connexion au serveur sortant SMTP free.fr a expiré ...

Que puis-je faire ?,?

Since applying update 115.10.0, Thunderbird will not close correctly and will not relaunch until task is ended in task Manager. This is true on a windows 7 PC and windows 10.

I have been struggling with this problem for about 6 months now and no-one I've asked has been able to help me. Even my computer guru failed me! I think it was after an update about last June when I started having this problem An nothing I've tried has had any effect. I had a Geek Squad guy on the phone with me for about 45 minutes to no effect. He said he'd never seen the problem before. I have business emails on that account so I don't want to risk losing them. Can anyone help me please? Christine

As a longtime user and a regular subscriber to Mozilla, I can’t get access to Thunderbird. Reason is that I had to repair the hard drive and now I am locked out. I am unable to insert a master password because I never had one. Reason being that I have used Thunderbird for years and years before that was required. To say I am frustrated is an understatement. None of your automated advice has a remedy. Should I install a new version of Thunderbird and begin afresh? John Cotterell ( an Australian supporter of your project)

I can receive emails to my (protonmail.com server) email account on Thunderbird. But I cannot send emails. This is the error message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: Error: no such user. Please check the message and try again."

Thank you for your help!

Hi, I have Windows 11, Intel processor, 64 Gb RAM, TBytes of SD storage. Lately I have been experiencing issues displaying email with attachments. It is intermittent, but occurs when I display an email with one or more attachments such as PDFs. I have a preview window open to the right of my mail list. If I click on the item in the list I see a properly formatted email in the preview window .. for a few seconds. Without me touching anything, the mail converts to HTML and the attachment is gone. Redisplaying the item goes right to HTML. Further, the HTML has nothing to do with the original message. If I go to my mail server the original item might still be there, but it might be gone. I have not seen a pattern to determine why some are gone. I need to solve this. I don't see this problem described in previous posts.

Attachments: tbird_before.jpg - preview email with attachment (personal data obscured) a few seconds later it switches to tbird_after.jpg and I cannot get the email back.

when I try to start Thunderbird, I get a window that says "Your computer must be restarted to complete a previous upgrade Thunderbird. Do you want to reboot now?. I've rebooted several times now, scanned with PC Matic, rebooted again, tried to uninstall in Control Panel, and get the same window. How do I fix this?

Already invested time creating some html code for email signature on thunderbird. Wanted to create something prepared for dark modes on IOS. Everything was fine until I detected on IOS (dark mode)some white rectangles outside my email signature code. It´s a problem that I cannot solve because it´s outside my code, and I´m wondering if you are already aware of this issue.

In case you want to test my code on a Thunderbird HTML email signature and see the result on an iPhone (dar mode), you can get it here: https://codeshare.io/dekBnR

'just added 2nd gmail address to Thunderbird. Suddenly getting verification requests. I go through that process then asked for phone # for verification code only to be told the number already used too many times . Now what?

in my 'podcasts' folder I have ~2 pages of folders of the type feeds.json-xxx.corrupt where xxx is some number, see attached image.

With the intention to re-subscribe to my feeds later, I have deleted all other folders in my podcasts folder. Trying to simply delete the feeds.json-xxx.corrupt folders did not work. How can I get rid of them?

(I am using the portable version of thunderbird)

The latest version of Thunderbird has lost the Advanced Search button. I can still access it from Control/Shift/F so the function is still there, but no obvious way of accessing it
