On Saturday morning 27 June 2026 I tried to login my Orcon email account via Thunderbird (which I have been using for a long time). But my login didn't work, I got a message saying "login to POP3.orcon.net.nz with username habitation failed." On 30th June 2026 I reported the problem to Orcon.
Orcon gave me the following settings for Thunderbird. I have done that and even made a new account: Incoming Server Type: IMAP Mail Server: imap.orcon.net.nz Port: 143 SSL: Off Authentication: On (username and password required)
Outgoing SMTP Server: Mail Server: smtp.orcon.net.nz Port: 25 SSL: Off Authentication: Off
Since then I have spent many hours and going around in circles with Orcon's Technical Support to resolve this, but no luck. They blame Thunderbird. I used Thunderbird Troubleshoot Mode. The message that comes up reads: login to server mail orcon.net.nz with username habitation failed. Please can you check that your server settings above are correct? And if there is a bug? Irma

Hi,
I'm running the latest version of Thunderbird 140.12.1esr on 15.7.7 (24G720) on an M1 processor.
I'm witnessing Memory leak > Thunderbird who usually use 800MB jumps to Gb up to 60Gb
It makes this version unusable.
Here is a loom of the incident: https://www.loom.com/share/0b8e661b42d64d749d80adfd71fd1e04

Anyone can help ?

Please let me know if it is safe to remove the older version of Thunderbird in the Installed Apps list. I also question whether the size of the app in the list is accurate; 250 GB seems quite enormous in a 500 GB hard drive. Thanks, Hans

Hello community,
at my place of work no one can send or receive mail anmore using Thunderbird. The problem suddenly appeared last monday. No changes regarding the network or settings in Thunderbird happened prior to this.
Here's what I tried so far and things I can rule out:

Hello all,
Apologies if this is going over old ground. I've tried the usual Repair Folder fix without success and I'm cautious about trying anything further without some expert input for fear of doing more damage.
Thunderbird version: 140.12.1esr (64-bit) Windows version: 11 Server type: POP, messages not left on server Inbox " Folder properties" reports: 16384 messages. 13.8GB on disk
The Entire contents of Inbox disappeared after the following sequence of actions: 1. Tagging a selection of messages (in Inbox). 2. Making only those tagged messages visible (using Quick Filter). 3. Selecting all of the visible messages (select first, shift-select last). 4. Deleting the selected messages (Del key) The intended messages were successfully moved to the Deleted folder.
The Inbox now appeared empty. At this point only tagged messages were set to be visible but these had been deleted so an empty Inbox pane seemed correct. Resetting the tags visibility of Quick Filter did not make the messages reappear.
The messages are however visible and openable when doing either a straight folder search or when using a search folder. Inbox Folder Properties reports that the messages are still present and the reported size on disk seems appropriate for the number of messages.
Messages in all of the other folders are visible.
At this point I did a complete Export of the profile. When I discovered that Windows would not recognise the resulting .zip file I also did a straight copy of the Inbox file within the profile folder to a safe location (I understand that the export .zip file is intended for re-import to Thunderbird and that Windows might not recognise it).
I then did a Repair Folder (within Folder Properties dialogue). This made no difference although the size of the Inbox.msf file reduced dramatically (I didn't make a note of the before and after sizes).
I then quit and restarted Thunderbird several times. This at first made no difference. After perhaps 3 or 4 restarts however a relatively small number of files have reappeared in Inbox (a tiny percentage of the correct total). Curiously, most of these (but not all) are marked as spam. Ordinarily I would delete all messages marked as spam but there are probably some that I have missed. It looks rather as if the files which are now visible in Inbox are ALL of the spam messages plus a handful of others. Of the 172 messages which are now visible they were initially correctly reported in the folder pane as being 172 unread messages.
Another strange thing is that when selecting the Inbox on the folder pane, the small number of messages which become visible only appear after a delay of perhaps 10 seconds (previously this was instantaneous). When selecting any other folder, the messages are displayed instantly.
I'm not quite sure what best to do next. I haven't yet tried deleting the Inbox.msf file. Any wisdom will be gratefully received.
Thanks in advance.

We use Thunderbird because of its flexibility across multiple OS and interfaces. We have only one PC using Windows, and that is a Microsoft surface running Windows 11. On that machine, emails are, from time to time, delayed, sometimes by 12 hours or more.
The emails come through normally on Android and Linux machines, and we had no difficulty on the Surface until we upgraded it from Win10 to Win10. The emails can also readily be accessed using a web interface to the provider's Apache server. Meanwhile, asking Thunderbird to get emails consistently reports "No new emails".
This is a very intermittent problem, with no discernable pattern to when it happens, or how long the messages get delayed.
Can anyone give me some pointers on where to start troubleshooting this?

I am getting a lot of phishing emails. They all come from email addresses from "onmicrosoft.com". These I can find pretty easy. The other thing they have in common is this URL/'server name' in the Message Header "send.workwithshadow.com".
Is there a way to search and/or filter for text in the Message Header?
Thanks, Walter Cook

My recollection is that prior to a recent automatic update to Thunderbird 140.12.1esr (64-bit) when I had a message composition window open, there were "SEND" button and possibly a "SEND LATER" button (to the left of the addressee and cc addresses in addition to the keyboard shortcuts (CTRL ENTER and CTRL SHIFT ENTER).
Following the update, there is no longer anything to the left of the addressee information. I have checked the toolbar menus, and there do not appear to be any button options. I can still send messages, but the lack of the buttons is a hindrance.

I have a similar problem to others reporting a connection time-out. But the circumstances now seem different. It is getting worse. First thing today, I noticed that Thunderbird emails (current/up-to-date version) were taking several minutes to finish sending. After sending 3 successfully, but slowly, all further emails failed, as per image attached. My wife's computer, using the same email provider, etc, was working okay. I checked and compared the account setting, and they were slightly different (no idea why) so I altered mine to match the other PC. That didn't make any difference anyway. Then (a few hours later) my wife's PC started having the same problems as mine, as if it's a spreading disease. Could it be a virus? Thanks.
I have had to change my email providers password where do i ipdate this on thunderbird.
