Thunderbird Community Forum

Apologies if this is a very basic question but I've searched for an answer and not found one that works. I'm using Thunderbird 128.4.3 on a Windows 10 desktop PC.

If I click on a message which already has several replies, each reply is opened in a separate tab. I thought there was an alternative to this, and indeed a found a piece about it, which includes this advice:

Enable threading on a folder... Open the View menu... In the Sort by submenu, choose Threaded. Your messages will be bundled into tree structures that can be expanded or collapsed with the > or v arrow next to the subject.

Unfortunately, when I looked at the settings for a few of my folders, the Threaded option was already ticked. But the ladder-with-indents display I w as expecting (and hoping for) doesn't appear. I'd be grateful for any advice.

Many thanks.

stopped sending emails. a new error message : login to smtp comcast.net with username( the only email address I have ever had) failed. i have no idea what to do. Yesterday I got a completely different error message about some authentication B.S. a couple of people have responded with suggestions that I dont understand. how do you check something when you dont know what it should be ?

I am running Thunderbird snap 128 esr on Ubuntu 24.4. A few days ago the usual alert popped up advising me that a new version of Thunderbird was available. I duly closed the programme, waited a little while and then reopened it. But on checking I found that it was still stuck on 128.4.2, while the release notes say that the latest version is 128.4.4. Yesterday the alert appeared again. I again closed and opened the programme but found it to be still on 12.4.2. The same thing happened again today. Any idea why Thunderbird is apparently not updating? NB: Each day the alert is reducing by one the number of days in which it says Thunderbird will be automatically updated.

My PC did a windows update, a few days ago and now my thunderbird account will not send or receive emails. I have checked the server settings and they are the same as on my phone, but I can send and receive via my phone but not on my PC? Any help would be gratefully accepted.

I do not receive attached files in my emails. As far as I know all my server settings are correct. I have disabled my VPN so that is not interfering as it does with sending emails. Thunderbird was set up to preview pdf docs but it doesn't.

Since today, when I opened TB on my M1 mac, the cursor suddenly started multicolour circling and nothing happened. below the following message comes host contacted. sending login information Force quit TB but nothing changed. restarted the mac but nothing changed switched off wifi . then the circling stopped and could check, delete old email. the moment wifi is switched on , the cursor starts circling and cannot do anything. i think TB is not connecting to internet. Please help solve the problem

Dear all, Since two days my e-mails are downloaded multiple times, i.e. I receive one and the same mail up to 10 times or more. I have 3 accounts, but only two of them have this problem. The account without problem is with a different provider. What could be the reason? What could I do? Many thanks and best regards, Ute

I just left from Postbox (on macos) since this program has been sold to another company and is not maintained anymore. Postbox is designed after Thunderbird. It has a convenient feature: displaying Location in the headers of displayed messages. For those users who have a lot of mailboxes, this can be quite helpful. If no add-on can do this, I suggest that it is implemented in Thunderbird itself.

Dear Sir or Madam, Since last monday I'm unable to receive Thunderbirds messages but can send and the 2 emails went into my local folders file now instead of my daviddss2007@aol.com sent file (see attachedment). I am unable to carry out any functions of my current files in daviddss2007@aol.com (eg move, change or delete). I've also noticed if I try other methods to retrieve messages I get the 1st attachment each time on my screen. I've tried checking my Settings / Account settings with my very limited experience and all the settings appear to be correct according to other blogs I've read. As further info when I open my Thunderbirds page it is not normal for the page to show permanently daviddss2007@aol.com: Connected to imap.aol.com... (see 3rd attachment). Normally it would search for emails received in my INBOX and if nothing found remain empty?. I hope the attachments assist - so PLEASE HELP Dave S Smith

I want to send some attachments with Thunderbird but suddenly, yesterday, I am unable to get My Documents to open and select the required file. I can open Thunderbird as normal, and I can send text only emails, but when I select "Attach" then My Documents comes up but as soon as I click on ant folder then I get the message "Attach file - Not Responding". The window just stays like that until I close the programme.

This a new problem from 1 day ago.

I am using Windows 11, 64 bit Pro, fully up-to-date; I use Hitman Pro, fully up-to-date, 64 bit; and I use Malwarebytes, fully up-to-date, 64 bit. I have a Lenovo Thinkbook i7 with 1gig hard-drive and 16 gb RAM.

I keep everything current and up-to-date, and programmes like Adobe Acrobat 2020, Hitman Pro, Malwarebytes are all paid-up subscriptions and all up-to-date.

Perhaps someone might have a solution to save having to to reformat my Email programme to Firefox or MS Messenger or some other thing.

I started using Thunderbird several months ago. I use Windows10 and Edge; using the settings advised by optus. Optusnet is my email server. With some difficulty I downloaded my address book via a CSV file. Emails to or from Yahoo addresses do not arrive. A sent message records as having been sent and is in the sent box but is not received by the addressee. Arriving emails do not arrive from Yahoo. All other email addresses appear to be delivered ok. I have double checked all of communication settings. Please advise.

New user here. I am trying to clean out my inbox (over 10000 emails). I select multiple emails trying to delete them. However, no matter if I hit the delete key, the trashcan, or right-click and select "delete selected messages"; only 1 email is deleted.

What am I doing wrong?

The latest Thunderbird releases have been crashing regularly, with these submitted reports. I'm trying to ascertain what I need to do to mitigate or eliminate the crashes.

etc, ad nauseum going back to 03 October.

In the last 2 weeks my wife Thunderbird refuses to send emails. The attached image is the error message. I got Telstra to reset her P/W, but Thunderbird still asks for a P/W. Using her details on Telstra webmail, messages are sent with no problem. I had same problem back in September, but I can't remember how it was solved. Your help would be much appreciated. Regards Ilio Pieroni

I copied Thunderbird folder in on my old computer to thumb drive. I Installed Thunderbird on new computer. I replaced the Thunderbird folder on the new computer with the data from the old computer. The folder on old computer had over 9,300 files. I ran the Thunderbird on the new computer. The old mail data was not shown. I was asked to create and new mail account the new computer. Mail from old computer did NOT appear. What is needed to get all of my mail, addresses and calendar data to the new computer. A large number of files are in the folder. see a sample of the names are attached,
