Thunderbird Community Forum

A message pops up when I try to send an email:

Add Security Exception You are about to override how Thunderbird identifies this site Location: smtp.xplornet.ca:587 This site attempts to identify itself with invalid information Unknown Identity This certificate is not trasted because it hasn't been verified as issued by trusted authority using a secure signature

I can't send or receive emails on my 2 email accounts

I had a number of files saved as "drafts" up until yesterday .. Now the most recent ones have suddenly disappeared -- (Everything after 8/29/24)  ! ! ! I had some important information saved there... Is there a way to recover those files???? Thanks for the assist.....11/11/24

I'm using the latest edition of TB and have started coloring my folders. How do I color subfolders? Do I have to do each separately or is there a way of coloring all subfolders with the same color under a given folder? Thanks, Dave

I use Thunderbird as an email client, and a POP3 connection to Virginmedia to download emails. This has worked pretty well for years. In the last few weeks the email content has been very slow to load. Although the list of emails in the inbox in Thunderbird appears quickly, when I select an email to view its content there is a delay of perhaps 5s while it says 'Loading Message...'. There is a similar delay when deleting a message.

Once a message has been loaded, it can be re-visited without a delay, but if marked as unread there is again a delay next time it is read. This is also true if I work offline, so it can't be Virginmedia's server.

I have another account using an IMAP connection which doesn't suffer from any delay. Thanks if anyone can advise.

Since my last update 'Thunderbird' is giving issues never experienced previously!

Freezing of screen on loading - takes about a minute to make progress.

Click 'send' - "not responding" - one or two minutes to become active again!

Same issue when clicking any other function!!!

Any advice greatfully received.

Thanks.

Dear community, 25 years ago i was using a macbook. The mail app had this feature: I could use whatever keyword from the contacts in my address book (f.e. people in the same company, or the same region, or everyone that i had added a word like "friend", "business", "sailing" etc) to create a "smart group". I find this very convenient and since then i always add some keywords to my contacts. I migrated to Linux some years ago and i am missing this feature again and again. Is there any way to configure a mailing list according to contact-content instead of doing it manually? If not, is there any email client that could do that?

Thanks!

I have installed Thu nderbird on my new Windows 11 Laptop. My old Accout has been installed just two files are missing Outlook Express Import and Drafts. How can I reactivate them. Thanks for your help Harald Schmadtke

thunderbird version 2024 - toolbar customization: missing: "delete" and "junk"

Dear ,

we send a note as i handle average day, some 1000 emails in thunderbird.

for handling this , we use thunderbird last 10 years, where as the mail toolbar is:

previous - next - (delete ) - (junk )

In all versions up to 2023 , we would install above 4 (four ) settings on one line after each other.

In the new version from 2024 , the settings between: ( ) , are no longer in the main possibilies, but

we must use these settings on the line under; which takes far more time than all on one line.

Is it possible to have the ( ) settings, in the next new version , back again , like before ??

Nice greetings,

Suddenly, possibly due to an update but unsure (started on 6th November), my emails no longer sent in Thunderbird due to the above message. I am still receiving emails in Thunderbird. I have checked all of this with plusnet and as I can send and receive without problems in webmail, this is being seen as not a plusnet issue. In terms of trying to resolve, I have tried adding my password in to the box, have tried checking all of my smtp settings against those advised to no avail. Has something changed... There seems to be many similar threads but not sure if mine is the same so creating a new thread.

I've been having this problem for probably about a year now. I have 9 accounts (5 Pop3 and 4 IMAP), and the passwords are stored by Thunderbird. I click the send/recieve button and everything downloads...until it doesn't. I go the settings/ saved passwords and what was a long list is very short...it has the MS oauth stuff for outlook.com emails and nothing else.

Over time I've found a relatively easy workaround. if I click the offline button in the lower corner, eventually it will prompt me for all the missing passwords and I'll be ok. But I have to exit and re-enter Thunderbird for that to work. If I do it in the instance after a download failure...it just hangs.

I use Firefox, and I noticed it happened one time after a Firefox update and I thought that might be an issue, but that didn't happen on the next update. There is nothing overt or obvious with my computer that would explain it...no dropped connections or errors...

I will note that I generally keep the computer and Thunderbird updated...but not necessarily immediately after the latest update is released. Thunderbird is at 128.4.2esr now. Windows 11, 1 yr old computer.

I do he the Thunderbird data on a NAS accessed over a LAN. I've been doing that for a long time with no issues.

No other changes on my end see to be the issue. Any ideas?

Thanks for any advice.

For the last three days I've been unable to receive or send emails from Thunderbird. The following messages are being generated:

1.Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) timed out. Try again.

2. Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.telstra.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

I've confirmed the settings with the ISP (Telstra) and the Telstra webmail works so they say everything is OK at their end.

I've turned off Malwarebytes, AVG, and PrivateVPN and closed and restarted Thunderbird and still no success. I've read multitudes of info on the internet and tried all sorts of different things to no avail. The only success I've had is to connect the laptop to my phone and use the phones data through the wifi phone network. Thunderbird then receives and sends emails. However this is not a sustainable solution.

Any assistance would be appreciated.

Bonjour J'avais créé une adresse mail en "mailfence". Je l'ai supprimée, elle n'apparaît plus dans "mes comptes" mais, depuis, j'ai un message tout le temps:

"Authentification requise- Mozilla Thunderbird HTTPS://mailfence.com demande un nomd'utilisateur et un mot de passe. Nom d'utilisateur.............. Mot de passe..................."

Où se cache cette adresse supprimée que je ne retrouve pas?

Merci

I am using Thunderbird 128.4.2esr (64-bit) with IMAP where all mails are moved to a folder structure in the local folder.

Since the latest updates of TB, I see that some of my folders under "local folder" suddenly become doubled like

Inbox/FolderA Inbox/FolderA-1

The original FolderA contains sub-folders and even sub-sub-folders. The newly generated FolderA-1 seems to contain all messages from the original folder, but just plain without the sub-folder structure.

It seems that the new FolderA-1 was generated as a kind of backup. It is hard to decide if this new folder can be deleted. The AddOn "Remove Duplicate Messages" does not work here, since it only works on a single folder. Moving all messages from the new folder into the original one does not help either, since the AddOn does not compare messages between folders and their sub-folders.

How can these problems be handled?

Seeking knowledge if possible, on how to import email sub-folder contents from another email provider (in this case, 'The Messaging Company') into Thunderbird. The "Import Tool" in Thunderbird appears limited to only a few sources that it can import from, however I'm unsure if there is another way. Any help would be greatly appreciated. Thank you in advance.

When I move an E-Mail from the in folder to a storage folder it is lost. Undo will not bring it back. It is just gone. This has been happening since the new release. I had no problem with moving item to folders with the prior release.

Thanks for your help.

For years I used Thunderbird to process my Earthlink emails. Thunderbird suddenly stopped accepting my Earthlink password, which I repeatedly tried and reset. Is something wrong with my Thunderbird settings? Mac IOS 13.7.1

Bonjour, mon problème est que depuis un certain temps,je ne peux plus insérer de nouvelles adresses de courriels sur Thunderbird. Mention (écrit en jaune)impossible de se connecter au serveur.Merci de me répondre. Gérard Voici l`adresse courriel ou vous pourrez me rejoindre :Gerard3830@gmail.com.

I followed Mozilla's official instructions for transferring and Thunderbird profile to a new device (running Fedora 40 and Thunderbird version 115). Thunderbird seemed to read my profiles folder correctly, as all my accounts and RSS feeds were present after I copied the old profile to folder to my new .thunderbird directory. However, after downloading the header files for the emails I have received since switching computers, it then tries to download all 60,000 emails or so on my gmail account even though most of these emails should be included in the profile folder already - it looks like have 6 GB INBOX file within this profile.

Is there a way to get thunderbird to read the profile without redownloading all the messages from my accounts? I unfortunately no longer have access to my old windows machine that this profile is from, just the profile folder itself. Let me know if there is anything I can do!

I am unable to send emails from my Optusnet email account through Thunderbird. This also happened a couple of weeks ago, and was resolved with Optus Tech support by updating the SMTP settings, but they don't seem to be able to help this time. What settings do you recommend? Or other solution?
