Hi Guys, please help to fix a very strange problem, that more and more Emails don't match up with the Sender and show different Message content (see attached Screen Shots) Never happened before ... why now ?? Thanks in advance, Werner P.S. my Thunderbird Version is 128.9.1est (64-bit) and my iMac is on Sequoia 15.5

Looking at the screen, which identity does everybody think this message is going out as?

We observe those three possibilities. See the first image. Apparently the first possibility is the one that is chosen. I'm talking about just an email address with no name.

Okay, in the second image it turns out it was not the first possibility that was chosen it was the second possibility.

However at the bottom of the screen again we see it seems to be saying it was the first possibility.

No I'm not saying I ever expected it to be the first possibility. I'm just saying that this needs all to be 150% more clearer.

I'm not asking any questions I'm actually reporting of bug, yes.

Recently I have noticed some changes in the way my Thunderbird downloads POP3 messages. Previously, it would be common to ask for new messages once a day and receive upwards of one hundred of them. But in the last month, this number has been limited to about 35 at a time. If I ask immediately again, I get about 35 more, and this pattern continues as long as there are messages in queue waiting to be downloaded. I am not sure if this is due to changes in gmail, where most of my received messages originate, or to changes in Thunderbird itself, or to some sort of third-party hack. Now that I have trained myself to keep on asking until there are no more messages coming down, this change does not cause me much difficulty, although initially it sometimes caused me to overlook messages because I failed to keep asking as long as I should have. Apart from that, it does not seem to be harmful as far as I can tell. I'd just like to know if other people have noticed anything similar, and if anyone knows what is causing it, and whether it has some hidden advantages over the way things used to work.

large tranches of emails disappeaed from Thunderbird folders but are on the server. How do I force a download to restore them? Using windows 10 and latest Thunderbird

So starting this morning, new email shows up on the server, but not in Thunderbird. Clicking on the get e-mail link shows it checking, but it doesn't load new mail into Thunderbird. It appears to be on the server, but not putting it into Thunderbird. Spectrum was in the process of changing the website where we get mail, but it appeared to be okay yesterday. Any ideas? Thanks

the startup message at lower left always says "no new messages", while the icon in the taskbar indicates a number of new messages, i'm sending and receiving msgs fine

cleared Tbird inbox, closed Tbird sent a test message from outside email upon Tbird startup, the initial msg at lower left says: contacting host...then "no new messages" Tbird icon in the taskbar shows a red dot with a "1" click Get Messages icon at upper left, and you see at the lower left "downloading message 1 of 1"

since installing Tbird on Win11 this behavior has been consistent, the initial message at lower left always says there are "no new messages"

When I try to send, or receive emails the following notice pops up: 'Log in to server imap.comcast.net with username [edited from public] @comcast.net failed'.

I just downloaded Thunderbird to my new computer. It worked fine for a short while. Then it started deleting new emails as soon as they were imported. How can I stop this from happening?

I use Thunderbird for my WOW email. Today it stopped working (incoming) I even changed my password on WOW and have logged into my email at WOW with the new password. Thunderbird says Login to server smtp.mail.wowway.com has failed. Then asked me to enter a password. I did all that and it still has the error.

I just went through hell trying to figure out why I could not send emails on my comcast.net account when I had to reinstall TB.

Here's what worked for me:

Been using thunderbird for years, stopped getting new messages. Removed/deleted the accounts and tried to setup again and get error unable to login at server, probably wrong configuration, username or password. username and password are entered correctly, changed them just to verify, using default settings and appear to match what their supposed to be as documented. Gmail accounts... Any help appreciated...

I am getting the following message using Thunderbird "login to server imap.comcast.net with user id pspringer11@comcast.net failed" it worked until yesterday afternoon please help

My Android (Samsung S22) Thunderbird acct. sends some emails to Outbox where they become stuck and clicking "send messages" does nothing. Indiscriminate whether email has attachments or not. Sending it back to Drafts and resending ends up back in Outbox. Have tried all posted "fixes", short of uninstalling tbird and reinstalling. I am on home 5G wifi. WTH?

Hello,

My Thunderbird 128.12.0esr (64-bit) was working fine. It no longer displays any messages except the latest ones. They are filtered, they disappear into their folders, I can only see them directly on the email server. I also have version 140.3.0esr (64-bit), but it asks me to create my accounts from scratch. (Mozilla Thunderbird Flatpak en-USthunderbird-flatpak - 1.0 release notes).

Thanks for your help!

Xubuntu (Ubuntu 22.04.5 LTS) Thunderbird 128.12.0esr (64 bits) Firefox 128.12.0esr (64 bits) Zotero version 7.0.11 (64-bit) LibreOffice 24.2.5.2 (X86_64)

I have been using Thunderbird to access my comcast emails. I never had a problem with it. However, this afternoon, just out of the blue Thunderbird cannot download my emails, the following message popped up: "Login to server mail.comcast.net with username xxxxxxx failed." Then Thunderbird asks for a new password. When I enter the still correct password, it displays the same error message. I did not change anything in the settings before this error message popped up. I tried ChatGPT to get some answers, but whatever I changed it had no effect. I am attaching a screenshot of the server settings (I have of course removed my username). I would be grateful for any advice as to how to fix the issue. Thanking you.

Hi there,

I need to export my thunderbird account over to outlook.com. I'm hoping to just sign into outlook.com and add my current thunderbird email details for j.childs@mhslimited.net.

When trying to add this as a POP or IMAP I get an authentication error once applying the incoming/outgoing server and port details.

Can you please help with what details I need to do the above.

Thanks

Everything was working fine then one of the email addresses stopped working. I tried everything and finally deleted that mail box but still can’t access the emails via thunderird. Help
