My one iCloud email account has been working fine in TB for months. Today sometime TB (115.8.0) began unsubscribing all but a few of my iCloud email folders, including "Sent", "Trash" &c. All other email accounts in the client are unaffected. I resubscribed all of the folders, but they keep unsubscribing - that is, the subscribe process isn't holding and the folders it retains seem random. All the mail and folders on iCloud.com are intact, but TB will show them (some or most of them) briefly, then unsubscribe all but a few. I've tried deleting the account entirely (including data in Thunderbird folder) and re-adding - the problem persists. I've been bale to solve this one. Anybody?

bold text All of a sudden today Saturday the 11th Thunderbird stopped sending email on COX but it can receive them. It was working fine then all of a sudden the sending of email stopped. At first I thought that is was Cox being down again, (I've had connection problems this week). But while I was trying to figure it out I received a number of emails. I tried sending a test email to myself usually they go right away but it did not go.

I called Cox. They tech connected to my computer, made some checks, (updated Thunderbird) and after about 20 minutes it started to send messages. 10 minutes later it stopped working AGAIN. This started a four hour telephone marathon with just about every level of service that Cox has. I ended up with Complete Care and while I was on the phone with him and he was connected to my computer the service tech from Cox who was here to check my signal and modem showed up. He tried to look at the problem and could not figure it out. Note I can send and receive mail from the COX email website but and only receive email in Thunderbird.

Cox tells me it is a Mozilla or Thunderbird problem I'm telling them it is not that it is a Cox problem because the server is SENDING me email to Thunderbird but the Cox INCOMING mail server it not connecting to Thunderbird to receive emails. They claim that because I can send and receive on the web page but can not send with Thunderbird. I'm telling them it is a Cox problem.

Anyone else have this issue? Anyone have a solution? I'm shutdown here with over a 25 year history of emails sitting in Thunderbird.

I have established a group in Thunderbird. I want to send a group email to all the individuals in my group. I believe that in the past I could click on the group name in the address book and have all the emails within the group come up in the To line of the email. Now I have to click on the group and then on each individual, which sends their email to the To line, but then when I click on the second person, the email is sent to the individual in the To line of a new email. How can I choose at one time all the emails of individuals in the group?

I'm running Thunderbird 115.6.0. I used to have a little icon of a cloud, and a button marked New Message (to compose), both just above the listing of mail and local folders in Thunderbird's left-hand pane. Then I clicked on something (that I thought was for something else) and those two icons are gone. I have looked until I'm blue in the face but can't identify whatever it is that will bring these back. Can someone clue me in? Many thanks!

I've been noticing apparent duplicate messages within my unified folders inbox on my desktop recently.

Looking further I notice that one of my accounts has 'INBOX' as one of its subfolders which is where the problem appears to stem from. When I look at that account in isolation (ie not in unified folders) I can still see the inbox as a subfolder.

The subfolder 'INBOX' appears to be a duplicate of the account's main inbox (it contains the same number of emails), which may account for the appearance of duplicates.

At a guess this is probably related to inadvertent moving of folders. I find that when trying to use the scroll bar (to scroll down the subfolder list), if the mouse strays slightly to the left it will pick up a subfolder and move it unintentionally. This can cause all sorts of problems with disappearing emails and the folder structures showing differently on different computers.

In this case the duplicate email problem only happens on my desktop. On my laptop I can still see a subfolder named 'INBOX' but it shows as empty and I don't see the duplicate emails in unified folders.

It would be really useful if Mozilla could introduce a 'confirm folder move' feature as that would eradicate inadvertent moves.

How do I resolve the apparent duplicate emails on my desktop? I am somewhat reticent to delete the subfolder 'INBOX' for fear of the potential consequences. . .

I can receive emails but cannot send. The error message I get when sending emails. This began as of the most recent Thunderbird update:

Sending of the message failed. An error occurred while sending mail. The mail server responded: <mjndoug22@me.com>... Relaying denied. IP name possibly forged [70.109.132.97]. Please check the message recipient "mjndoug22@me.com" and try again.

I tried to attach/imbed a screenshot of my SMTP server settings but your Browse button below won't allow the paste.

How do I disable automatic translation of Thunderbird messages by Deep-L (or any other machine translator)? This morning I received an email from a family member, written in German. Underneath the original message was an automated translation into English by Deep-L. I didn´t ask for this translation. I speak German as a second language, as well as other languages, and I enjoy using my linguistic abilities. Furthermore, I don´t like my private messages being passed to a database without my permission. If I want a translation of a message, I´ll ask for it.

This is evidently a new, annoying feature. I had an email exchange in German with someone just a few weeks ago without this intervention. I have tried searching the settings tab on Thunderbird, but have not discovered anything about Translation settings (not under Language settings, as far as I can see).

How do I disable Thunderbird sending emails for unwanted translation? Thank you for your assistance.

I've been a Firefox fan for years. I thought I'd try Thunderbird. I'm in need of some help please as I'm going round in circles.

I am trying to link my btinternet email account to Thunderbird. Thunderbird cannot do it automatically so I have to enter the details manually.

I have all the right settings according to BT: Incoming POP 995, SSL enabled but not StartTLS. Outgoing Port 465, SSL enabled not StartTLS. mail.btinternet.com is used.

The User Name and Password are correct but Thunderbird cannot connect to the account. There are no Firewall issues.

Something is happening because BT have notified me of potential unauthorised access and I have to reset my BT password. Even when I enter the new BT Password Thunderbird cannot link to the account.

Any suggestions as to what might be causing the problem? Thanks.

So running thunderbird 115.10.1 (64-bit) and more and more issues:

• the app keeps getting non-responsive for long period of time, to fix this I have to force quit the app.
• at times when composing an email the app freezes where no typing occurs for seconds or typing is very slow or after typing awhile the text suddenly appears.

Seems to be happening more and more trying to figure out how it can return back to it's rockstar state when it was <99 version.

any help would be appreciated.

I have been using three email accounts on Thunderbird, all for a long period of time, and all without any issue. Recently the one listed below has not been backing up, and I receive this message. I am not techie at all, so any response needs to be dummy down to a 5th grader level. Thanks!

"Non-overridable TLS error occurred. Handshake error probably the TLS version or certificate used by server mail.q.com is incompatible."

Running 115.5.0 and want to export my contact list to be able to use it in a spreadsheet. The export function in the Tools dropdown only allows for export of "accounts, messages, address books and settings to a ZIP file." What happened to the ability to export just the address book separately to a csv file? Please help. Thank you.

Thunderbird runs slow...ie when I type an email I can easily type faster than thunderbird will accept characters....(this does not happen in other applications)...this happened about a month ago, and then stopped ( I have no idea why)...but the problem is back. I am running Ver 115.10.0 build 2024012173147. Rebooting windows 11 makes no difference.... I just tried to enter Troubleshoot mode and thunderbird stopped responding....Top line says Mozilla Thunderbird (Not Responding). Thunderbird is connected to my gmail account. ...and I run IMAP....with 'store all messages on the computer', but thunderbird wants to load every email from the server'

Any advice would be appreciated Rick

I can't receive emails at any address from those in Thunderbird. I have several addresses, some in Gmail but not all. And in each of them I get this message: The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: [AUTH] Invalid credentials. I am using version 115.5.2

I've provided all of the other data, no problem. But the <Your login> field has only "YOURDOMAIN\yourusername" in it as a format hint. The field carries an Info symbol, but it's greyed out.

There are many possible domains, e.g. microsoft.com, office365.com, outlook.com, each with possible 3LDs, and the domain-name of the organisation that provides my account.

The most obvious (MYORGDOMAIN\Roger.Clarke) gets the error-message: > Authentication failed. Please check the username and password. (I checked, and they're the same as I use for a webmail login there).

Leaving it empty gets this error-message: > Unable to log in at server. Probably wrong configuration, username or password. (That about covers the possibilities then ...).

Hyperlinks in Thunderbird (115.9.0 64 bit) running on Ubuntu 22.04.4-LTS have quit working overnight. Too my knowledge nothing changed. I have followed all the steps in the document "Hyperlinks in messages not working" with no luck. 1) My default browser was Chrome. Changed to FireFox. No Luck. Changed back no luck. 2) Check that no application is specified for HTTP content can not be followed No Preferences option exists under the menu in my version of Thunderbird. Checked in settings found nothing matching the description. 3) Checked for incorrect preferences. Used config editor. Their is no Reset option for the settings. Found the referenced setting. Switched from True to False and then back again, hoping the might reset it. No Luck 4) Switched to Safe mode from the Help menu. No luck.

New to Linux, just set this system up 2 months ago. Migrated my Windows Thunderbird database without issue and it was working fine until this morning.

In need of suggestions. If uninstalling is going to be required, I need to be able to do it a way that does not lose my historical email records or my cardbook address book of 1000 names.

Thanks

I initially had a problem with deleting empty folders from the Local Folders Trash. I found another post, followed the directions and they were gone. I moved a folder to a different folder as a subfolder and the same files reappeared in the Trash again. These will not delete from the Trash. Thanks for your help.

I recently archived locally about 10 years worth of emails successfully (the emails were removed from the my ISP's servers and I opted for a yearly format). I can easily find these in Thunderbird but of course they are not on the mail server anymore.

Settings info: I have Message Archives set to "Archives on Local Folder" followed by my email address (I set it up with this name so that I can find the archives specifically for backup by my Sinology server).

However, my Sent folder (shows a paper airplane icon) is missing, although I also downloaded it and thought it would be saving locally.

When I verified my Archive options in TB, I noticed that while I had selected "Yearly archived folders" I did not select "Keep existing folder structure of archived messages". I assume that this is a mistake on my part?

My questions are: Q1. Where are my Sent emails - would they be mixed in with received messages in each yearly archive? Q2. How do I access these sent emails within the TB search window?

Any advice and suggestions would be most appreciated and thank you. C.

Hello. I need help getting Thunderbird to stop marking and sorting certain emails as threads. Seems to be completely spontaneous and for no apparent reason, even in the inbox. I have never actively marked emails as threads. I've tried to remove the "threads" function in the folder settings, but it doesn't seem to have helped in some cases. I also need help with getting the email "unstuck" from the thread structure, I have tried "Ignore threads" and "Ignore subthreads" with the result that the email disappeared. The documents I have seen have not been of any help. Reply preferably to my usual e-mail address, have a bit of ours with mail in the G-mail account.

  Please Bosse

Hello, Most received emails word wrap in Thunderbird, but a small proportion overflow the right side of the viewport. Is there anything I can do to make them wrap? Is there anything I can ask the senders to do to eliminate the horizontal scroll bar? Alan.
