Hello,

I have noticed a difference in behavior (for some time now, but I haven't noted exactly which version: first half of the year) in the alert for tasks that are “oudated” but not “completed.”

On ESR, an outdated task continues to sound at the launch or from time to time. On release, an outdated task no longer sounds (it remains green in the list, but that's all). And we are no longer notified if we don't go and check.

I don't know if this behavior is intentional or if it's a bug, but personally I switched to ESR because it's too problematic for me to no longer have alerts on overdue tasks.

Please let me know what you think...

[To reproduce: create a task with a start time 5 minutes before your test, no end date, and a reminder 0 minute before].

I have used Thunderbird on my laptop for years and have never had this problem before. until last week. Thunderbird will advise that there are, say, 6 emails to download but it wont down load them. I can access them from my Android tablet and see them on my email server). An initial check online suggested there might be a space problem on my laptop. There was, and I cleaned up the contents of my laptop. Problem disappeared. Today the problem reappeared. Thinking there could still be a space problem, I cleaned out my considerable archive in Thunderbird. Restarted Thunderbird - no luck. There were a dozen or so emails on the server, and I could read them on my Android tablet. I rebooted the laptop. A message that it was downloading new emails, but nothing downloaded although they were still on the server. I uninstalled Thunderbird and downloaded the latest version. I could email from the laptop to the Android and reverse but nothing else. I deleted all my emails on the server. Any suggestions about how I should proceed? Regards Alan Brooks

Hi, My Thunderbird email has stopped downloading emails from my server. I click to download emails, get a message saying "downloading 1 of 25" but no progression from here onwards. No messages are downloaded. I have made no changes to the settings and it has been working well for many years. wifi is connected.

Thank you for help to restore this.

Hello!

I'm in the process of migrating from Evolution to Thunderbird, but I seem to have hit a snag. In Evolution, there is an "Archive" folder, which any archived messages go into (attachment 1). This same folder also appears in K9 Mail (my mobile email client), and similarly is treated as special. In that first attachment, you can also see the "Archives" folder created by Thunderbird, which Evolution does not give any special treatment to.

However, in Thunderbird, the "Archive" folder is completely absent, both in the folder listing on the main page and in the "Copies & Folders" settings where an Archive folder would normally be selected (figure 2). Notice that the "Archives" folder is still present, and is now given special treatment, but the "Archive" folder is absent. Checking the contents of the "Archives" folder confirms that it doesn't contain the emails which K9 Mail and Evolution have been archiving.

Is there a way to access those archived emails from Thunderbird?

Thunderbird Version: 128.12.0esr via Flatpak OS: NixOS 25.05 Email Host: migadu.com (IMAP)

Happy to provide any more info if needed!

Thanks!

The TB Solutions only provide information for a tar "bz2" file. I downloaded a "xz" file (thunderbird-140.0.tar.xz), how do I install this?

Thanks for any help or solution.

I wish to update my current version of 128.12.0esr within my Ubuntu 24.04.2 LTS OS.

I figured TB was currupt. I decided to uninstal TB. Usually TB is downloaded from the Mozilla TB site. was necessary to download TB from the microsoft store, which caused me to lose my 300 addressbook contacts and the recovery address book service would not work allthough I received the message the address book was found on the server. Again the messages were not displaying at all in the all or inbox, or important folders which gave me the idea to uninstal and reinstal. I think the program is pretty straight forward, but maybe I wasn't clear about the messages not displaying in the all or inbox folder, that may be important.

I'm aware David replyed to me. Usually if I uninstall Thunderbird and reinstall thunderbird, my addresses are usually there, but this didn't happen this time. My folders weren't loading correctly so I thought TB may be currupt, so I felt it may be worthwhile uninstalling and reinstalling, but may be the worst idea unless there is a way to get the contacts back. I think it's pretty straight forward, what I hope for a goal or at least learn why my address contacts did not load. Usually I download TB from the Mozilla TB site, but it sceems necessary to get the app from the microsoft store. It just sceems like the address book recovery services are not there, so I need a older version.

All of the emails in my Archive folder and its sub-folders came up empty today 7/5/25, but were present yesterday 7/4/25. I have tried to locate hidden folders to restore them, but to no avail. The computer has not been rebooted. The content of all the other folders and accounts are as they should be.

Any assistance appreciated!

Hello,

I'm trying to add my secondary email account to thunderbird but I couldn't make it work. I've been using thunderbird for at least 15 years and this is first time I'm seeing anything like that. I think Account Hub is a new feature, I had to reinstall my PC and fresh Thunderbird installation came with it.

The account hub asks for my name and email address. I enter both and as soon as I click continue it says my username or password is incorrect. I don't get any prompt for password. It hangs and gets stuck here.

As an alternative I tried entering a made up email address (something like asd@ba.da) and then it gets into manual settings. I thought I could get it sorted that way but I was wrong. After I fill the form and click continue I get the blank error message. if I click advanced setup it gives me an error about cleanup property. I also get an error message sayign incoming server already exists, that's probably because I have another email account on the same server, but I'm not sure why this is an issue now. Can't I have multiple email accounts on the same mail server?

Probably this has something to with my mail server's autoconfig setup. However I believe user should be able to manually enter account config, incoming/outgoing server etc. At the moment I'm totally blocked and I can't add my second email account to thunderbird.

Thanks

The Local Folders Account has a setting to set the Message Store Type. By default it's set to "File per folder (mbox)". How can I switch to Maildir?

Note that in global Settings, I have already set up the Message Store Type for New accounts to "File per message (maildir)". But I can't create a new local folder account.

1) Thunderbird 128.12.0es refuses to disable conversation mode, when View/Sort by/Unthreaded is selected for a folder.

2) Thunderbird 128.12.0es does not show the number of selected messages in the Status Bar when I select multiple messages, instead showing the number of selected conversations.

How can I disable conversation mode?

Told found address book, but no contacts or need to be able to rollback to a previous version which has my contacts. Otherwise there sceems to be no screenreader issues, app works grate other than no contacts.

Hi,

Since the last update, downloaded on 4 July 2025 to my computer, thunderbird will not download any new emails from my server.

Please assist.

Thanks,

Melissa

I have 7 RSS Feeds installed and working.

The problem is that 5 of them only update when I right click and update manually but the first 2 update normally when I select "Get Messages".

I've checked each feed and they all seem correct in Properties.

Anyone out there have a suggestion or solution?

Any help will be greatly appreciated.

I am using MacOS 10.13, Thunderbird 115.15.16ESR: my Hotmail worked until 15 May 2025 and then it would not download new emails. Screenshots are available if you want me to post them. I got an error message: "authentication failure while connecting to server outlook.office365.com". I updated Thunderbird to the latest for my OS: 115.18.0ESR. Still no new emails. I deleted my email account on Thunderbird and tried to reinstate it. Now I get an error message when trying to set up the account: "Unable to log in at server. Probably wrong configuration, username or password." I tested my password by logging into my Microsoft account with it on my browser. I can also login to my email using Firefox, but I want my Thunderbird email client to work again.

The configuration I am using is: I use my normal hotmail password in the password field. I also set up a new App Password with Microsoft and tried that without success. With the 115.18 update there is a new field: Your login. I just put my hotmail email address in here. incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 
outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2 (I have also tried: smtp-mail.outlook.com)

I enabled 2-step authentication with Microsoft in my Microsoft account more than a year ago. Interestingly, I don't get a prompt on my iPhone Microsoft Authentication App when I select Done when trying to set up the hotmail account on Thunderbird.

Please help. I am desperate, and I have wasted a lot of time on this without success. Cheers

I sometimes look into a sub-folder under email inbox account (imap) in thunderbird and can see it is just updating. Is there a specific setting where I can keep all folders and sub-folders constantly updated?
