My Thunderbird has behaved very well for a decade or more. No issues and still the same. My question relates to the delete function. When I press delete I get a warning of a delete email with a chance to go back. I changed this to see what happens and now I cannot find how to return to second chance as this works best for me. Possibly simple but how? regards Replytree

Hello,

I just switched to Thunderbird from Outlook and so far it seems nice but one problem when I click on the get messages cloud icon on the top left of the screen I receive no incoming messages. Now if I go to one particular email account (I have 8 email accounts) and right click and left click on get messages, new messages come in.

So my questions is, why doesn't all my mail come in when I click on the get messages icon? Am i misinterpreting this?

Thank you!

Thunderbird can receive emails but I cannot send them. I get the error message per the screenshot below concerning SMTP.

I have a MacBook Air with Mac OS Sequoia 15.7.2. The error started yesterday (21 November). Just finished conversing with Optus support and they say that it's not at their end: webmail works okay, can receive email and send it (will note there was a brief hiccough earlier today when could not send from webmail, but okay now). All settings as recommended (port for incoming server actually different from what Optus recommends, but when I changed it from 995 to 110, Thunderbird stopped being able to download emails, so changed it back again. Port for outgoing is as recommended, 25.) I tried lowering security, as suggested by Thunderbird help list, and no change so restored it.

I have the latest version of Thunderbird for Mac, 145.0.

My partner, who also uses Thunderbird, cannot send emails either. He has an older Mac running an older OS.

I have included two images, the second one showing details of selected server. When I clicked 'fetch certificate' it failed. Does that signify anything important?

The error console shows a lot of information, which of course I cannot understand, but can screenshot some of it if that would help.

No firewall, no virus protection, no VPN.

Any ideas as to what might be going on?

I'm using Thunderbird with my GMail account. I've added all the GMail folders and can access them without any problems. However, I'd like to add a new folder. Is it possible to do that in Thunderbird or do I have to log into my GMail and do it there? I'm using Thunderbird 145.0 on Windows 10 Pro 64 bit.

After updating my Thunderbird mail application from version 128 to 140, the shortcut icon for composing a message is no longer responsive and I cannot create a new message from it. I can no longer create a new message without right-clicking on a sent email and using “Edit as New Message (E)”. How can I get back to being able to create a message from the message creation shortcut?

I cannot send emails and always get the same error message, no matter what steps I have taken. This has been the situation for nearly 48 hours. During this time I have undertaken the following steps, as advised by Thunderbird (TB)/ Optus and Google (not in order).

Checked SMTP server settings (many times), Re-booted the Router, Uninstalled and reinstalled TB, Changed the number of Server Connections to Cache from 5, down to 1 (as suggested by the TB Notification), Tried sending a test message to my other email address on several occasions, but got the same error message. I have checked my Webmail account and can send and receive from and to my email accounts from within webmail.

As required in the TB help file, The following information is provided: SMTP settings (attached). Mail Provider is Optusnet. ISP is Firefox. Antivirus is Trend Micro Maximum Security Version 17.9. OS (details attached).

If I have neglected any required info please ask. Any assistance would be greatly appreciated.

Thank you. Flin

I'd like my search results to include messages where the search item is in the Sender or Subject but it appears to find only words in the body. Is there a way to include this? btw, the window pane on the left shows a filter but I don't know how it got there or how to delete it. Is this relevant? Is there documentation on how to use the search feature to specify folders, binary searches, etc? Thanks

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!

Bonjour, Depuis quelques temps j'ai un soucis d'envoi avec ma boite mail. J'ai deux adresses mails : davangel49@orange. et gaecterrien49@orange.fr Avec l'adresse privée, je peux envoyer et recevoir sans problème Avec l'adresse pro (gaecterrien49@orange.fr), je peux seulement recevoir des messages mais pas envoyer. J'ai une message d'erreur qui s'affiche et qui me dit "mail rejeté. Identifiant et adresse mail appartenant à deux utilisateurs différents".

J'ai contacté Orange également. Le problème a bien été réglé de leur coté (je peux envoyer un mail et le recevoir de ma boite mail Orange sur gaecterrien49@orange.fr mais pas à partir de Thunderbird. Pouvez-vous m'aider à régler ce problème? D'avance merci A. TERRIEN

i cannot get Gmail configured in Thunderbird. ive deleted it and re tried countless times but is keeps saying wrong credentials. ive followed all the guides and done everything . what is NOT happening , is Thunderbird does not open a browser to sign in with google. why?

Enough is enough—every update brings problems, crucial add-ons stop working, and now drag and drop attachments have stopped working. It's really inconvenient. Maybe it's time to stop this nonsense and implement paid subscriptions or purchases, but in a way that makes everything work.

Hello, Apparently, when changing the name of the .thunderbird folder, to hide it, Thunderbird 140.3.0esr (64 bits) continues to exhibit messages. I do not find where they are located. Any idea? Thanks SG

Recently when I have opened Thunderbird I have found that there are no emails at all in any of the folders, and the message says "No Emails found" although the count shows that there are nine. This is the same for all my email accounts. If I open help and go through the troubleshoot they all come back. Its not the ad-on's, as when I disable them the Emails still do not show. The version of thunderbird that i am using is145.0 (64 bit).

Help please.

Drag and Drop attachments to the desktop stopped working again with Thunderbird 145. Steps to reproduce: You receive a mail with an attachment. You drag an attached file from this message and drop it onto the desktop of your Mac to download it. The attached file is not saved to the desktop (or any other folder I tried). This is on MacOS 26.1 MacMini M4. Please fix asap.

I'm not able to log into yahoo e-mail via Linux Firefox (145.0 (64-Bit)): The error message is "We were unable to log you in. Please try again from another device." I can log in with Chrome (Linux and Windows) and Firefox (Windows). My issue is to switch from POP3 to IMAP in Thunderbird. There the same error message occurs.

I'm using a Windows 11 laptop with a 14" laptop with a 1920 x 1200 resolution. I'm using Thunderbird to access 5 email accounts, calendars and cardBook. I'm looking for suggestions and tips about the best layout to maximise the display of my email information with the minimum of scrolling.

Thank you.

Running Linux Mint 22.2 Cinnamon and it has just updated Thunderbird to V140.5.0esr. Reopening TB all my carefully crafted layout has disappeared. I can only see one account with favourite folders underneath. I can't see the Sent Mail folders or the Personal folders which I rely on heavily, nor any of the other accounts. This has totally messed up my day.

I have the Folder Page View Switcher in, that was working after the upgrade but I innocently changed a setting on it, and it disappeared. I cannot find anything to bring it back.

Can I revert to a last good set up?

Please help.
