why is everything going to trash in thunderer but not in Comcast.net email what do i do o i eed to reinstall it and uninstall it

can not  do restore point

I am using MacOS 10.13, Thunderbird 115.15.16ESR: my Hotmail worked until 15 May 2025 and then it would not download new emails. Screenshots are available if you want me to post them. I got an error message: "authentication failure while connecting to server outlook.office365.com". I updated Thunderbird to the latest for my OS: 115.18.0ESR. Still no new emails. I deleted my email account on Thunderbird and tried to reinstate it. Now I get an error message when trying to set up the account: "Unable to log in at server. Probably wrong configuration, username or password." I tested my password by logging into my Microsoft account with it on my browser. I can also login to my email using Firefox, but I want my Thunderbird email client to work again.

The configuration I am using is: I use my normal hotmail password in the password field. I also set up a new App Password with Microsoft and tried that without success. With the 115.18 update there is a new field: Your login. I just put my hotmail email address in here. incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 
outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2 (I have also tried: smtp-mail.outlook.com)

I enabled 2-step authentication with Microsoft in my Microsoft account more than a year ago. Interestingly, I don't get a prompt on my iPhone Microsoft Authentication App when I select Done when trying to set up the hotmail account on Thunderbird.

Please help. I am desperate, and I have wasted a lot of time on this without success. Cheers

Hello,

Recently I have started to have emails fail to deliver to a certain domain and the message that comes back is

550 DKIM Sender Invalid - envelope rejected.

I am using Thunderbird v128.8.1 esr (64-bit). Extensions installed are: 1. Attachment Saver (Deimios, v.0.2.2) 2. FileLink provider for Send (Teal Dulcet v2.1.1) 3. Remove Duplicate Messages (Eyal Rozenberg v0.6.1)

I have been in communication with this client for several years and not had this problem before. When I send email to the same recipients using WebMail there is no problem, it is only when I send from Thunderbird.

I am not using any encryption type of setup.

Has anyone come across this before? Does anyone know of a solution?

Thanks, Franc.

Hi,

I'm experiencing issues with threaded view in Thunderbird (version 139.0.2 on Windows). Some threads do not display all messages -only a few emails are shown (e.g. 2 out of 8), and others are missing from the thread view even though they are present on the server. Rightclicking a message and selecting "Open message in new tab" sometimes works (but still doesn't show all messages), and sometimes it doesn't open a new tab at all. the missing messages do exist on the server, and I can find them using Ctrl + Shift + F , but they do not show up in the thread, nor do they appear via Global Search, even though the global index has finished building.

I have tried the following: -Right-click folder > Properties > Repair folder -Deleted and rebuilt global-messages-db.sqlite (global search database) -Reduced IMAP mailbox size from 140GB to 110GB -Waited for reindexing to complete

But the problem persists. It seems that Thunderbird either doesn’t associate all related messages with the same thread, or skips them entirely in display and search.

What can i do to fix it? Thanks in advance

How do I restore emails from an email backup (that is NOT a backed-up profile zip file) that has been saved using ImportExportToolsNG? I used ImportExportTools NG to create an email backup. The backup is in the forms of files in a set of folders (calendar-data, crashes, datareporting, extensions etc.). It is not in the form of a zip file.

How can I stop Thunderbird from displaying its own advertising/donation page on my browser when I open Thunderbird? It opens this page on my default browser, no matter which is chosen: https://www.thunderbird.net/en-US/thunderbird/128.0/whatsnew/?locale=en-US&version=128.6.1&channel=esr&oldversion=102.8.0 If the browser is not open, it will open it.

This is the result of trying to keep Thunderbird from automatically upgrading. In newer versions, the option to choose not to upgrade has digressed from difficult to not available. It did such an upgrade, so I de-installed and reinstalled my original version, only to have this issue.

I was very satisfied with my old version AND see no need for new any of the "features" or look. And, especially, once such a setting is made, don't want Thunderbird, or any other application or app, changing it back. This is a violation of privacy at best.

Worse yet, Thunderbird is attempting to penalize the customer for making a choice on their own computer by infecting the machine with nuisanceware.

Hello!

I'm in the process of migrating from Evolution to Thunderbird, but I seem to have hit a snag. In Evolution, there is an "Archive" folder, which any archived messages go into (attachment 1). This same folder also appears in K9 Mail (my mobile email client), and similarly is treated as special. In that first attachment, you can also see the "Archives" folder created by Thunderbird, which Evolution does not give any special treatment to.

However, in Thunderbird, the "Archive" folder is completely absent, both in the folder listing on the main page and in the "Copies & Folders" settings where an Archive folder would normally be selected (figure 2). Notice that the "Archives" folder is still present, and is now given special treatment, but the "Archive" folder is absent. Checking the contents of the "Archives" folder confirms that it doesn't contain the emails which K9 Mail and Evolution have been archiving.

Is there a way to access those archived emails from Thunderbird?

Thunderbird Version: 128.12.0esr via Flatpak OS: NixOS 25.05 Email Host: migadu.com (IMAP)

Happy to provide any more info if needed!

Thanks!

Am getting this message along with a recurring download of a specific email (keeps coming back even after deletion) that does not allow any other new messages to be downloaded. I do see new emails on my phone but will not read into Thunderbird??

Error: "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

Tried: Troubleshooting, closing Thunberbird and reopening, rebooting windows system, compacting, etc. to no avail....

Hi, Win 10 Pro new installation. Dell Optiplex MBR type Bios.

I had saved a recent profile to an external drive in its own name (i.e. not the profiles folder)

After the new Win 10 installation, I downloaded a new copy of Thunderbird.

I then copied the saved profile into the new Profiles folder, selected it in Choose user profile and started Thunderbird.

Thunderbird opened but not with the saved (8+ Gb) profile, just one new email account and asking for passwords to other email accounts I used before, and no folders.

I went back into the profiles folder and renamed all other profiles "OLDxxx999, but still the same one new email account when I opened Thunderbird.

I desperately need the saved email folders - I don't mind loading all the email accounts again, just need my court case history folders.

How can I force Thunderbird to use the saved profile, or can I identify and individually load in the saved local folders?

Thank you for any guidance towards a solution.

Hi all. Is it possible to send 400 mails and attach different .pdf files.? I have the e-mail list in a cvs file, and 400 *.pdf files placed in a folder. I know that it might be done i Google mass mail, but I would prefer to use Thunderbird the same way. Does anyone know if this is possible?

I got a new PC with Windows 11. I installed Thunderbird 136.0.1 , activated the private calendar, and entered events there. For events with a reminder that have a specific duration (e.g., Wednesday from 10 AM to 11 AM), I receive notifications. However, when I create a full-day event and want to be reminded, for example, 1 day before, I don't receive any notification. Additionally, events with a reminder are not shown in bold in the calendar overview (whether they have a specific duration or are all-day events). Can you please help me?

I just updated to version 140.0 and now my subfolders are out of order. Is there a fix for this, short of fixing it manually? I miss how they were automatically alphabetized. That went away when manual reordering was implemented. I can't grab a bunch at the same time and move them, since the order is so messed up.

Hi, My Thunderbird email has stopped downloading emails from my server. I click to download emails, get a message saying "downloading 1 of 25" but no progression from here onwards. No messages are downloaded. I have made no changes to the settings and it has been working well for many years. wifi is connected.

Thank you for help to restore this.

The Local Folders Account has a setting to set the Message Store Type. By default it's set to "File per folder (mbox)". How can I switch to Maildir?

Note that in global Settings, I have already set up the Message Store Type for New accounts to "File per message (maildir)". But I can't create a new local folder account.

Hello,

My Thunderbird is on 140.0ESR - just updated yesterday. This morning I am noticing that when I open an email to read, and then close it, my inbox automatically scrolls from the top of the box to the place where that just read email is located. It used to just close and I could open the next one - now it goes through this momentary, fast scroll and then stops at the most recently read. It doesn't seem to matter if there are unread messages in the mailbox - it does the same thing when all messages have been read.

Very strange behavior - and just started with 140.0ESR.

Any ideas appreciated. Thanks!

I've been using Thunderbird for decades. I have Thunderbird set to automatically download messages every 5 minutes. Platform: Computer Win11 Home, Thunderbird 128.10.0esr (64-bit), POP3 connection (also with IMAP connection on a MacOS computer.

But a new issue is now occurring. Every so often now, I realize I haven't received any new email downloads in some time. I click on the Get Messages button (or right-click and select items individually), but nothing happens - no "Host Contacted..." message in the Status Bar. It's like the Get Messages function is completely disabled. It is only when I quit then restart Thunderbird does it successfully establish a connection and download the many queued emails.

Please let me know if this is a known bug, or if there is a way to submit this as a bug. Also let me know of any other information you would need in order to help debug this issue. Thanks!

• After the update launching thunderbird daily, from anywhere, main `.exe` or shortcut links
• It opens a cmd prompt, I am using Windows 10 build=19041, I also use `windows terminal canary`
• I had no issues before the recent update, is there a way to roll back the version? to the previous commit?

I keep getting the error "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox." when I try to get my messages, or delete them.

I have tried: Restarting TB Shutting off my anitvirus and restarting TB Rebooting the computer

This started sometime yesterday (7/6) morning, at a time when I was not doing anything on my computer. Or at least that is the last mail that downloaded successfully I am using release 140esr (64 bit) supposedly released this morning.
