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!

Hello,

is it possible to set the width of the columns in Thunderbird Task section using the userChrome.css? If so, what are the CSS commands for the columns?

I ask this question because with the help of the userChrome.css is it possible to set the width of the columns in the email list, like so for the "Date" column:

1. dateCol {

max-width: 112px !important; min-width: 112px !important; }

I just updated to version 140.0 and now my subfolders are out of order. Is there a fix for this, short of fixing it manually? I miss how they were automatically alphabetized. That went away when manual reordering was implemented. I can't grab a bunch at the same time and move them, since the order is so messed up.

Hi there,

just installed Thunderbird (v140) and added my corporate office 360 email account (via owl) as well as a few hotmail accounts. The weird thing is that I do see my corporate calendar but not my hotmail calendar. An attempt to add the hotmail calendar failed because I don't know what to fill in at 'location' - it pre-fills in 'hotmail.com' but doesn't work neither does copy/pasting the webmail address (https://outlook.live.com/calendar/0/view/week).

I'd much appreciate ideas & solutions.

thnx

Not receiving emails addressed to multiple recipients. Senders are in address book but the emails are not downloaded. Download message says "Downloading 1 of 12" but no messages downloaded. I cured this a couple of days ago by going into my webmail account and deleting a group email that seemed to be blocking my account. I tried that today with another group email but without result. This is a major problem.

Older messages in Thunderbird are listed but their content is not showing. I have been using TB forever and I never had that problem before. It is POP3. When I try Folder Repair, the program simply throws out all messages whose content is not accessible (so if my Sent folder has 40,000 messages it comes back with a Sent folder of 2,000). Clearly something got corrupted but I am not sure what. In the picture below, the header is visible but (a) not clickable (different header showing) (b) no content is displayed. I used to copy the content of the TB folder to my laptop and back (while keeping different profile names assigned during installation. The problem seems to have started when I changed profile names and began using identical profile names on both the desktop and laptop. Also, the total size of the folders is around 65Gb, in case there is a size limit. Any ideas? Thanks

I am unable to send emails because i get an error message :"sending message failed, because connection to outgoing server (SMPT) smpt,centurylink,net timed out.

Hello -I am having problems opening files in thunderbird -I keep getting '"This file does not have an app associated with it for performing his action.

I have uninstalled and reinstalled t/b several times but nothing works -any solutions please. I cannot even open 'help' on my desktop - I am using another computer to write this

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.

Thunderbird won't open inbox, just shows the donantion page, even though i made a donantion short ago, and made a new one now .

i wrote a note already asking for help, but I cant reach the "my messages" box

i have this problem for a week already, not able to use thunderbird

please help

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.

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
