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 often have many tabs open (25+) I have made it so tab shrink way more then normal (I like the way chrome handles tabs where they basically just shrink infinitely. Firefox doesn't do it's even with my twerks but ohwell.)

so when i want to click on a tab with audio playing at a small size i often mute the tab instead of clicking on the tab

Where and how can i remove the mute button that appears when hovering over tabs with audio playing?

I have never found that mute button useful so removing it will not impact me

Hi,

I have just setup a new Office 365 account in Thunderbird and when I try to send an Email from the account, I get the attached error message.

When I click on "Enter New Password", the window goes away for a moment and then pops up again. There is no chance for me to put in a new password.

I know that I need to use an app password when not using Outlook which I have generated in my Microsoft account settings.

I have tried to go to "Settings -> Privacy & Security -> Saved Passwords" and have deleted all Microsoft related saved passwords. When I access my Email account again, I get prompted via the web login of Microsoft (i.e. different from the attached error message) and the app password I generated doesn't work, only the general password for my account works.

I have restarted Thunderbird and updated to the latest version, but it made no difference. I have gotten it to work on another computer, but on my mac mini, it doesn't seem to work.

Before I remove the account completely and add it again, is there any way I can fix this as I don't want to download all the messages again?

Is this a known bug in Thunderbird?

If any developer is reading this, In order to reproduce, you would have to follow these steps:

- Setup a Office365 account using the regular password used to login to the O365 website. - When sending the first email, enter the same regular password -> the first time, the dialog to enter the will show up, but it will fail, because the app password wasn't used - Then try to send again, click on "Enter new password" -> no dialog to enter new password is coming up.

I am using Thunderbird 115.10.1 on MacOSX Sonoma 14.1.1

The settings I have used are: server name: outlook.office365.com port: 587 username: my full email address Auth Method: OAuth2 Security: STARTTLS

Thank you for reading this. Looking forward to a reply.

After the last couple of Thunderbird updates, I have been experiencing a really frustrating issue that I can't seem to resolve.

Only when I receive emails from one specific recipient and I go to reply to them, the font size is suddenly really large, and the spacing between new lines is huge.

Even if I set the font options to the same as if I was replying to a different recipient or creating a new message, it still appears really large.

What's worse is even if I make all these adjustments and get the font size and formatting looking okay, the actual sent message is even more out of whack and has all these spacing problems.

Does anyone know what might be going on? No other mail client I use experiences this issue whatsoever, and this issue is only occuring with this recipient.

Microsoft Security Essentials detect multiples times Trojan in Firefox setup. By Uninstalling and reinstalling, the issue was not resolved.

I have just upgraded to 115.9.0(64-bit). Now when I select "Send to email client" I get a message that either there is no default email client or the current client cannot fulfil the request. This did not happen before the upgrade

My e-mail inbox shows a high gigabyte use-age rate, but I only have a few messages in there. I get my messages a couple of times per day and delete emails I don't want to keep. Now it will not get all my new messages as it saying I have run out of disk space. It seems that messages I delete don't really get deleted?? even though they go to trash and I clean the trash folder. I have tried compacting but that didn't work. It seems to be only on my win 10 laptop, as my XP computer is working fine. I have plenty of disk space left on the hard drive. Thanks in advance Bob Parkman

Seems after the latest update Thunderbird will not receive some emails. It has stopped receiving emails coming from some cell phones and some .com emails. Some cell phone emails work and others that previously did do not anymore. I do not understand the random situation. No settings have been changed nor is there any setting to correct this. I even reinstalled Thunderbird.

Any suggestions would be great. Thanks

If you give me an email address I will send you the screenshot of my error message.

Or, call me NOW at [removed from public support forum]

Thank You. Marty Straka

I belong to a number of newsgroups where I save technical data from that is in the form of email. 1. How can I save messages, with header intact, to a text file as I could with Eudora? 2. When I start Thunderbird, what email is loaded into memory?

Hello

I have a bizarre issue with attachments.

I open all attachments in their respective programs rather than preview within Thunderbird itself (I have also tried opening in preview but I get exactly the same problem).

When I receive an email with attachments, mainly Word, Excel or PDF docs, I click to open the attachment but nothing happens. If I save the attachments to my computer and try to open it says the attachment is empty or corrupt.

But, if I click to forward the email, I can then open the attachments as normal by clicking on them in the draft email and also then save them to the computer and they open as normal.

I am running the latest version - 115.10.1 (64-bit) and I have noticed this issue for about the last week or so. Otherwise everything seems to work as normal.

Any ideas on what is going on or ways to change this.

Thanks in advance

I've been using T-Bird for some time now with no problems. Yesterday Xfinity wanted me to change my account password, which I did. This morning I tried to check email and got an error message stating the incoming mail server didn't accept my password - the new one I'm assuming. After several tries I switched it back to the old password which still didn't work. I'm giving T-Bird the Xfinity login password -- is that correct or is there something else that T-Bird is looking for? As a side note -- I just spent 8 days in the hospital and they've got me on a medication that really messes up the higher functions of my brain. I feel as though I'm in a heavy fog and half asleep. Any help would be appreciated... and THANKS~!

Archiving older messages:

I know how to archiving a years worth of messages -- one message at a time, or by selecting a hundred messages at a time IF they are all in the same folder. A painful way to archive dozens of folders full of a years worth of messages.

Why should I be forced to drop into a folder to select the messages? Why not provide a mechanism to archive FOLDER?

I'd really like to select Local Folders (recursive) and hit A to archive -- and be allowed to select Messages older than.

This allows mail to be stored/archived easily by year - and keeps the active Local Folders small and resilient (keeps Thunderbird from being overwhelmed with large folders that seem to bring the app to its knees.

Created several email mailing lists. Stored them in the Personal Address Book (PAB). I'm sorry, but Thunderbird doesn't seem to work like any other email client. How do I address an email using one of those mailing lists in the PAB. Tried typing the whole name of the mailing list in the To: field. Didn't work. I'm not entirely stupid but it doesn't make sense to me.

Hi my email address (all services) has been migrated to a new company so I've got a new server name and new imap and smtp port numbers all of which has been duly filled in in the correct boxes (as far as I know). The new server name is mail.mail.coop the old one is smtp.iomartcloud.com. Everything seems to be working ok, ie. there's the new account listed in the left-hand window with all the folders and subfolders and all the emails in the correct places, all working fine inc. send and receive. The old iomartcloud account is still there just above it with all the folders etc. but no send and receive because the service has now been closed by the server company (all my emails have been transferred to the new server. If I go to my webmail page also all is ok inc. send and receive. I have set the new mail.mail.coop as the default and I've been trying to find out how to delete the iomartcloud one.

The problems I have are two: 1. I can't seem to find any way to delete the iomartcloud account from thunderbird. 2. Whenever I close and restart thunderbird it's forgotten the mail.mail.coop account/identity. I have to go to new account > existing email (my email address hasn't changed) and put in name, password etc. It all works fine again but next time I close thunderbird......

I know the server is ok and I know the passwords, port numbers, server addresses, etc. are ok because it all works fine each time I create the new account (for the 50th time!), so there's some other problem I haven't yet identified. I've searched on this forum and elsewhere, and hunted all around the settings menus but to no avail.

I wonder could the two things be connected? If I could delete the old account maybe it would solve the other problem. Note that both the email address, name and password are the same for both accounts, only the server address is different (and the port nubers maybe as well). And could the second problem be to do with the security settings of my browser or os? (brave browser, linux zorin os).

Sorry rather a long post! Hope someone can help me! Justin

I checked with my website/email host who show no problem. I was able to see new messages I missed there, so the site is working. I checked with my internet provider, Centurylink (DTTH) who says I'm paid up and there are no restrictions on my account, which shows active. Settings hadn't seemed to have changed, but I received 2 domain emails since then, nothing else. I noticed that the program updated right around the time of the problem, but it comes up and acts normally. 'tis a brain scratcher, it is.
