This is a very strange issue. Some of the messages in my inbox, when selected do not display the message itself. Blank box. I looked at the message source and there is nothing displayed but white space in the box. The messages that are not displaying are before 3 August 24 and back in time to the year 2018. Those messages received in 2018 appear correctly.

Messages received after midnight (12:01 AM) 3 August display fine. Message source view displays the contents.

On that computer, I have other email accounts that display the messages correctly. Nothing missing. So whatever happened, only one email address account was affected. It is like something deleted that data.

Running Windows 10 Pro and latest version of Thunderbird. No extensions

Anyone that can inform me as to what might have caused this and tell me if it can be fixed, I would be greatly appreciative.

Thank you

After updating to Thunderbird version 115.12.2(32 bit) two days ago, I can no longer send emails. I get an error message "Authentification error (VM401)" I use Virgin Media. I can receive emails OK. I have not changed any server settings for a long time. I have been in touch with Virgin Media, they say the problem is with Thunderbird as I can send emails from on their one line system. I can also send emails from my Android phone. Any help would be appreciated.

I've setup Thunderbird as my new email client but I'm getting the following error message on both mailboxes. Went through manual confi and it said all was good. Can't figure out what I'm doing wrong. Any help greatly appreciated tks - patrick replies to: prpa1440@gmail.com

Hello,

I am running Thunderbird 115.13.0 and cannot get e-mail from my bellsouth.net account on my MacBook Pro #6 computer. I get the error messages below. I have another MacBook Pro #5 running Thunderbird 102.15.1 that is receiving e-mails just fine. As far as I can see the server settings on the two computers are the same. Any advice about how to proceed? Thanks for any ideas.

'Have enabled and disabled. restarted, both times. Tried troubleshooting mode, and cleared the cache. Could not find the setting in the config screen. Not sure I was looking for the right thing, anyway. Your help will be greatly appreciated. John Looze

1. Looking for settings to show/unshow folder counts in the folder list. My TB shows the counts. The example on TB web page does not show counts. 2. I am unable to get Unified Folders to "stick". I click it in View > Folders but it then unselects. Help appreciated, Chris Sackett Using new Nebula, which looks great!

I suppose the best place to start is when/where I think this problem started. Approx three to four weeks ago my thunderbird program stopped downloading emails from my server (Spectrum/RR). I say Approx because the problem sort of sneaked up on me without me realizing it was there.

I was using W7 and my hard drive was pretty much full and I was constantly getting messages that my email could not be downloaded due to lack of space. I started deleting stored emails and emptying the trash, which sort of kept me up and running for the past couple weeks. All this time my Gmail account continued to work as it should, downloading every email that was sent to me, but the Spectrum/RR account was spotty at best.

So today I fired up a new W11 computer for the first time. One of the first programs I installed was Thunderbird. When I attempted to set up an account using Spectrum/RR the process failed. I typed in all of the correct information, Name, Email, and Password but the account will not finalize. Instead, I continue to get the same message that the Configuration, Username or Password is incorrect.

I have since successfully logged into my Spectrum/RR web mail, so I know the username and password I am using is correct. I have also talked with Spectrum Technical support, and they have verified that what I am using to log in is correct.

I hope I didn't ramble on to much and someone can help me !

Hello. Through sfhowes' generous advice, my Thunderbird is now connecting to my hotmail/outlook accounts. However, something strange is happening. When I launch Thunderbird, I get the password prompt that I show in the images. The message seems to be coming from Microsoft. This happens for every account I have in Thunderbird. It's rather a nuisance. Then, after I enter the password, the pane disappears but I get the error/warning message from Thunderbird (I suppose) that I show in the second image. Does anyone, please, know what's going on and how I could fix it? Thanks, Barry.

Background: I've been using Thunderbird for desktop for a couple of years now, and had no trouble with it. I use it to connect to email inboxes from a hosting provider. In the past, one of them was going through Google Workspace email (linked to my own domain), but I decided to go with Thunderbird instead. I did connect to Gmail once (if I recall correctly), to download emails from there. Then, all the mail server settings were set to those of my hosting company/my domain and worked well.

Today, after starting it up, I received a notification of a Thunderbird update (new looks, new nesting of connected emails, card-like look of emails), and I received a prompt to log in to the long-defunct Gmail account. I closed the window and went searching for the reason. All my mailing server settings seem to be fine. In the Thunderbird settings, in the Privacy&Security tab, Passwords section, I found several saved passwords relating to said defunct account. I deleted them all in hopes of solving the issue. Unfortunately, this only changed the prompt: from asking me to sign in to the specifically-named defunct account, it's now asking me to sign into Google account in general while the popup's header still refers to the defunct account. I also went ahead and downloaded the newest update. My Thunderbird seemed already updated judging by the version number, though none of the new features seem to be enabled, and some note mentioned that it's not an automatic update but one that had to be downloaded. Unfortunately, it didn't help either. The PC had been restarted. The pop up appears shortly (~1 min) after the startup, and then at random points of Thunderbird being open.

I'm out of options and at a loss of how to get rid of that constant pop up, and I feel like I'm missing something obvious. I hope someone here might help.

Environment: Windows 10 22H2, Thunderbird 128.0.1esr 64-bit on two different PC's, "A" and "B".

Scenario and steps to reproduce:

(1) On "A", installed extension "remove duplicate messages" (version compatible with Tbird 128). Works fine. Profile on this PC is D:\Alice\Thunderbird\Main.

(2) Completely get out of Thunderbird on "A".

(3) On "B", launch Thunderbird accessing the same profile residing on "A" as mounted drive, "Q:\Alice\Thunderbird\Main". Mail, calendar, etc work fine. However, the extension is not available (No "Remove Duplicates" on context menu or Tools menu). On Tools :: Extensions and Themes, extension shows up with a blank (empty) icon.

(4) On "B", disable the extension, close the "Extensions and Themes" tab and completely get out of Thunderbird. Re-launch Thunderbird, go to Tools :: Extensions and Themes, and the icon has reappeared. After re-enabling the extension, it is active and works flawlessly.

(5) Then, completely get out of Thunderbird on "B".

(6) On "A", launch Thunderbird. It now exhibits the same behaviour for the extension: it is not available, and the icon is blank. Performing the same steps as in step (4) above restores the extension to its working state. And, you have probably guessed by now, it is no longer working on "B" !

Just to make sure this is not specific to this particular extension ("remove duplicate messages"), I installed another extension ("Quicktext"), and it behaves exactly the same (either singly, or with "remove duplicate messages" still installed).

So, it seems that you cannot use extensions from the same profile accessed via two different paths, one PC accessing it via a local drive and another accessing it via a mounted drive. I want to re-interate, before someone asks, that Thunderbird is completely down on one PC before I try to access the profile on the other PC.

Has anyone seen this behaviour on Tbird 128 ?

Thanks.

Since that last update (128.0) I can hardly tell the difference between read and unread messages. Particularly when there are just a few messages of the same kind with no basis for comparison. I've looked through previous threads and found some solutions that involve modifying scripts. I had ChatGpt help me with the maneuver , but it didn't change anything. I would also be satisfied with another font in the headline or another background color - just something that ensure sure I do not miss an important mail in the stack.

Hi, I'm running into the issue where I have a public certificate issued to security@companyname.tld as they don't issue a separate one for most employees, but Thunderbird won't let me use it for sending (I think it's used when replying?) it to firstnamelastname@companyname.tld

Is there a way around this?

Hi,

I have been using Thunderbird happily for a long time, most recently version 115.13.0 on my Ubuntu 22.04 partition. Recently I installed Ubuntu 24.04 on another partition, including Thunderbird 128.0esr, now installed as a snap package (it's a recent change in Ubuntu; instead of apt package previously).

The new Thunderbird correctly reads my emails (imap) but it cannot send emails, save drafts or mark emails as read on the server. So I have Thunderbird 115 on the old partition working perfectly, but Thunderbird 128 not working on the same GMail account (I also have the same problem with another non-GMail account). I checked the smtp settings carefully, they are identical between the two versions.

It's possible I made a mistake, but I'm at a loss about what is wrong. How can I diagnose and solve this problem?

(I know that I could reinstall Thunderbird with the apt package, but I assume that the snap package should work too and I would like to understand the cause)

I'd be grateful for any advice

after i have suddenly upgrade to newest version my autocount can't send the mail by mapi system integration in software. i use that program is inside autocount called 'send by email (Ms Outlook compatible)'.

thunderbird 115.13.0 how do i see my all folders with ALL of the emails? When i go to unified folders sent/inbox it flips the most recent email to the bottom, how do i flip it back, are there any videos, anywhere, that i could watch and learn from????? i can save us both a lot of tme if i could watch a video on how to do this? thank you...b³

for example: also how do i make a directed screen shot of a page? as opposed to the whole page?

Once again, since my husband suddenly passed 13 December 2024, I cannot send or receive email via my intoknow.com account.

Previously, it was somehow "repaired." Please, i need this account to stay active.

Having downloaded TB version 128, the details for TbSync via add-on manager states that it is not compatible with this version. My questions, as a first timer with TB are:

1. Can I still go ahead and use TbSync with version 128? I need it to get contacts and calendar from Outlook.com

2. Will the planned native support in 128 for Exchange ActiveSync allow for easy switch from TbSync?

3. I thought I would download TB 115 which TbSync works with, but all download buttons seem to point to 128 and I can't for the life of me find the actual download link for TB 115.

Thank you. Sep

After an update a few months ago, all installations of thunderbird always open the calendar tab when the program starts. Previously, calendar tab only opened if I opened it (or maybe if it was left open when last shut down, idr now, sorry). This is only a nuisance, having to close the tab each time I start tbird.

I didn't post about this immediately, as I figured others would experience the same issue (or related) and devs would fix the problem. But it has been several months now and this does get to be annoying. I know that merely clicking a close button shouldn't be that big a deal, but I don't understand why this would become the default; moreover, why there doesn't seem to be any way to disable the calendar or at least modify this new behavior.

I've been using tbird for at least a decade and found it to be reasonably simple to use. I use the calendar function, but only for some installations. I would appreciate being able to change the behavior of the startup or maybe just disable calendar altogether where it isn't needed.

Thanks.
