Thunderbird Community Forum

Hi your all,

I have used Thurderbird more than 6 years and it was really good for me without any complaints. However, I updated the email from Supernova to Nebular (128.2.3esr (64-bit) yesterday and I got the following message and I cannot receive any emails now. Fortunately, sending is no problem.

"Sending of username did not succeed. Mail server pop3.mailplug.co.kr responded: invalid command"

I searched the previous similar issues in the forum and I checked my status. However my own was the right one that people recommend.

Receiving Server: pop3.mailplug.co.kr / Port: 995 / SSL/TLS / Normal password Sending Server: smtp.mailplug.co.kr / Port: 465 / SSL/TLS / Normal password

Actually, I am using several pop email apps but I have no any issues on those apps except for the Thunderbird. The problem is Thunderbird is my main app. I am alternatively using outlook but really want to return to Thunderbird. Could you anyone help me out?

Thank you for your kindness in advance!

Most of the time Thunderbird is very slow, taking minutes to log in, minutes to download tiny messages, but sometimes is quick. Sometimes Thunderbird complains the password is wrong, but after three retries it accepts the password. Only occasionally it is quick as I'd expect. This has been happening for several months. I had hopes Thunderbird would find and fix the issue without challenge, but as the issue continues I am now raising it formally.

Hey There,

Hope everyone is doing great!

The body search feature is missing in my Thunderbird. Searching for any text that I know appears in a body also returns no results. How do I enable this?

Please let me know if it's a setting that prevents this option from showing up. ( Just a thought, if it is some setting, could it be grayed out instead with a tool tip text to show why it's grayed out instead of removing the option completely? )

Cheers, Tom

In Windows 11, the Address Book is accessed via an icon on top left of the TB main page or Alt+2. In Windows 11 is there a similar key combination to view the folders below Local Folders?

Hi I'm running version 128.4.3esr.

To prevent my inbox becoming very large I have created a folder called Archive and several subfolders such as 2021, 2022, 2023 etc.

Every few months I move old files from an earlier year into its appropriate subfolders.

I've been doing this for at least 10 years. When a folder is about 5 years old it is deleted.

My problem is that today I'm unable to move emails from my inbox to an appropriate subfolder. I get no response. It simply doesn't work as it used to.

Any suggestions gratefully accepted

I already tried putting Thunderbird as a shortcut into the C:\Users\<myAccountName>\AppData\Roaming\Microsoft\Windows\SendTo (aka. shell:SendTo) folder. But when I use the "Sent to" menu and select Thunderbird, the file to be attached just gets openned by Windows as if I had double-clicked on it. Thunderbird does not even open a new message.

I also tried changing the call of the Thunderbird shortcut in the SendTo folder to: "C:\Program Files\Mozilla Thunderbird\thunderbird.exe" -compose attachment= At least, then Thunderbird opens a new message. But it just writes the path\filename of the file to attach into the attachment section. When I then try to send the message, Thunderbird says it cannot access it under this path.

How are you doing this? Thanks!

I have an email account on Thunderbird (jetmayor@gmail.com). I can get to this account on one laptop but not on my other newer laptop. The screen asks me to sign in and shows my email address as above. Underneath the shown email address it says 'Forgot email?' Underneath this it says: Before using this app, you can review Mozilla Thunderbird Email’s privacy policy and terms of service. Create Account NEXT

Whatever I press it goes to another screen and says: 400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

The email address did work OK for months and I just don't know how to get it back. I've tried to delete the account and then reinstall it but that hasn't worked. My other email addresses are still working fine. I can still access the faulty address directly on Google Mail so I know it still should work. It's possible I have changed the password in the google account. I have tried this password in Thunderbird but to no effect. Is there a way to reinstall the faulty address? Help! Any help would be greatly appreciated.

Regular emails go fine. When I add attachment it says it goes but doesn't even though in sent folder. I go into sent folder and send as a forward and it goes fine. Using webmail works fine but I prefer thunderbird. Have been using it for at least 10 years. At the present time I have to send w/attachment twice and then ask the recipients if they got it. Lot of extra work. Help!

3 Days ago Thunderbird, Firefox and Windows 11 all updated at the same time. Now, every time I close and reopen Thunderbird, it takes me back to the "Setup your existing email" page, and I have to create a new profile and start over. I then restore my email and settings, etc. via a backup, only to have the same thing happen the next time I open Thunderbird. Firefox is being similarly affected, but not quite to the same degree. I don't lose my bookmarks, but all my settings have to be restored. I'm using Bitdefender Total Security, and have turned everything off, and the same thing happens. I've been using all these programs for years, and Windows 11 for over a year with no problems. Please help.

Hello ; I planed 3 days ago to empty my spams and by mistake I deleted all the content (all the e-mails) of the file Deleted (the dust-bin, or Trash, I don't know the word in English) as I clicked "empty Deleted" ; is there a way to restore those e-mails of the Deleted file that I emptied by mystake ? Thank you !

The print screen has only one option to 'Save to PDF' and I want to replace that to 'Print' I've checked the settings and everything for email in there except 'Print'. How do I get to a setting screen where I can make this change. I am old and not computer savvy so please give me every step so I can finally print attachments. Thank You

I get this message when I attempt to send an email

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-a2p-646770.sys.comcast.net resomta-a2p-646770.sys.comcast.net Excessive failed authentication, ESMTP server temporarily not available.

Whenever I reply to a message, the reply as well as the original appears in my inbox. I thought it might be related to Threaded Replies, but that is set in Sort>View to "Unthreaded."

How do I stop this? I'd like to keep the original message I rec'd. And if I need to see my reply I can go to 'Sent' folder. I don't need each and every message in a back-and-forth filling my inbox.

I'm using a X13 ThinkPad with 1920x1080 resolution on a 13'3 display with Linux (Arch) and XFCE desktop. For the best results I've increased the XFCE's DPI to 134 and fonts sizes to 10. It looks like the fonts of the size ~13 without DPI change. It's fine, and applications like Firefox like those settings.

In Thunderbird I've set the font size (interface) to 12 and in Settings the default font sizes for Latin and Other Writing Systems to 12 (both) and finally the interface font as well as plain text email and HTML e-mails without font sizes specified explicitly look natively and perfectly.

But there are some senders using clients that generate HTML e-mails and specify the font explicitly as 'font-size=12pt' in their body by default. The same as my 12 so everything should be fine. Unfortunately font in those e-mails is really HUUUUGE! I'm wondering if there is some setting that allows custom scaling but only the HTML messages. Or some pt to px custom scaling for HTML? Or some maximal size allowed in HTML?
