In the process of changing from Windows to Linux, I have entered the details of my email account and it is fine when I press re-test, but when I press done it is not fine anymore. The email is “freeuk.com” which is still active but Freeuk itself isn’t, but the service was taken over by Claranet with a “clara.net” setting, so I imagine that may be relevant. Any help (not too technical please) would be appreciated. Thanks.

Somehow I got 2 emails: gregory@gregorysantana.com and Gregory@GregorySantana.com The lower case shows a lock blue envelope and the upper case shows a lock red envelope. I don't understand the icon meaning of the lock icon and the color coding.

Further: I use command File, sub menu Get New Messages for All Accounts.

In the lower part of the overall panel, I see new messages downloading, but the new messages don't show up in either account.

How to correct, it is important.

It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

I still use Thunderbird on an old desktop and for the past month or more, I've discovered with some sort of communication error or the direct pop-up that I cannot login to server and it asked me to 'retry'/'Enter New Password"/"Cancel" and it's beyond frustrating. I'm on the verge of just uninstalling this for my emails and use another platform. Before so, since I've been using TBird for a long time, I figured I'd consult some experts here to guide me how to navigate this annoyance. ANY suggestions would be appreciated. Thank you.

How can one setup a sending email server with same address and username but different passwords?

When trying to setup 2 different accounts i find a thunderbird limitation using API email password which have same smtp server address and username and only differs in password.

Is there a workaround?

I am having problems accessing my email [redacted]@hotmail.co.uk I am currently using Windows 10 on my computer I sent you a very detailed email the other day unfortunately I am not sure if you got it because I could not verify it because I think you sent me a code or something to the very Email I cant get access to clearly as a 68 year old man who knows nothing about modern technology things like this are not what you need I am also classed as Severely disabled with various illnesses from Diabetes and sleep apnea to Ulcerative Colitis and mental health problems.I also have CTS in both hands so trying to type this out on my phone is not ideal I am not having a go at anyone but I would have thought that with the amount of intelligent people connected to technology organisations that one of them would have thought about this type of problem and came up with a simple solution it's not rocket science if the main problem I'm having is not being able to access my email and have no other accessible other ways to confirm things to you surely a freely available freephone number from the country you live in to yourselves or if you yourselves contacted the person Directly preferably on their home phone but if not their recognised mobile number and asked them some basic security questions by firstly asking them for two step verification to their mobile (if they have one) likewise I am aware not everyone had either a home phone or a mobile (or both) because of various problems I have encountered with verification methods that are not available to me or might be but I dont know how they work then surely I cannot be the only one? under the 1998 Human Rights Acts and Protocols Article 1 Protocol 1 people like myself are meant to have protective status especially here in Britain where the 2010 Equalities Act is meant to give us added protection and certain rights all I am asking for is to speak to someone who wont talk to me using Computer Jargon and at least has some Empathy and Common Sense to help me get this Sorted I use Firefox and Mozilla because I Like what you are trying to do but if you are going to cause people like myself the exact same problems I and others like me may as well just not bother with technology because the Stress it causes me in particular is simply not worth it. Thank you for taking the time to read this Tomb and I really do hope you can help me because I have no other options left PS I cant follow written instructions if I could I would not be in the position I am in Hence the need to speak to someone and not a Robot Thank you

As in the subject, my computer has sound everywhere else but, despite 'play a sound' still showing as ticked in general settings, no sound happens when an e-mail arrives. And, in general settings for 'when a new message' arrives, I can hit the Play Button there and the sound happens. How do I fix this?

Thunderbird has stopped downloading mail from the outlook account for my prime account, but my secondary account also outlook is OK. It kept asking to sign into my account then directed me to a web page to sign in for outlook, but it would only let sign into the 2nd account. I have tried uninstalling Thunderbird and re-installed it but still have the same problem.

Environment:

Thunderbird: 153.0.2esr (64-bit) Operating system: Windows Occurs with multiple email accounts Reproduced on two different computers running the same Thunderbird version

Description:

After updating Thunderbird to version 153.0.2esr, released on 4 August 2026, emails can no longer be dragged and dropped from Thunderbird to the Windows Desktop or any folder in Windows Explorer.

The problem occurs with all tested email accounts and folders. It has been reproduced independently on two different Windows computers using the same Thunderbird version.

Saving an email manually with Ctrl+S works correctly and creates the .eml file. Normal drag-and-drop between folders in Windows Explorer also works. Only dragging an email from Thunderbird to Windows Explorer fails.

The issue also appears to affect third-party applications that use Thunderbird to create or send emails automatically.

Steps to reproduce:

Open Thunderbird 153.0.2esr on Windows. Select an email in any account or folder. Drag the email to the Desktop or another folder in Windows Explorer. Release the mouse button.

Actual result:

The email is not copied or saved to the selected Windows folder.

Expected result:

Thunderbird should export the email as an .eml file in the selected folder.

Additional information:

Ctrl+S successfully saves the same email. The issue affects every tested email account. Thunderbird extensions were disabled, but the problem remained. Thunderbird Troubleshoot Mode did not resolve the issue. Restarting Thunderbird, Windows Explorer and Windows did not resolve it. Thunderbird and Windows Explorer are not running with different elevation levels. The problem was reproduced on a second computer after installing the same Thunderbird version. No relevant error is shown in Thunderbird’s Error Console when the drag-and-drop operation fails. The issue was not present before the recent Thunderbird update.

This appears to be a regression in Thunderbird 153.0.2esr affecting email export through drag-and-drop and possibly Thunderbird’s integration with external applications.

I have thunderbird installed on my PC, and my main email account is a gmail account. I download from gmail using POP protocol (SSL/TLS connection security, OAuth2 authentication). I have been using these settings for a long time (15 years?).

This afternoon, thunderbird stopped downloading my messages. No error messages : just "no new messages to download".

I can see (by logging directly into my gmail account using my browser) that there are new messages on the server. They're not spam or junk, and they're not getting downloaded into my (local) spam folder. They're not getting downloaded at all.

I still have room on the google server (it's about 87% full), and room on the hard drive on my computer (about 3 GB).

Здравствуйте у нас перестали работать метки помечаешь письмо меткой и оно сначала уходит куда надо в папку с этой меткой а потом заходишь она опять в изначально метке стоит, до 28 июля все было норм а потом начало криво работать и поиск тоже не все письма ищет раньше все показывал а теперь не все и приходиться искать по тексту сообщений тогда находит.

I have been using Thunderbird since over 7years on pop. I am facing issue since few days. I Have my personal mail linked to my website hosted on a unix server. I use thunderbird mails latest version. All sent mails were earlier visible in Sent folder. But now since a week only yesterday's mails are visible. All previous mails are in a subfolder by year 2026 in Archive. This makes it difficult to search sent emails. While this is not an issue for the Inbox where I can see emails from 2017.

Please suggest how can I restore all my previously sent emails since always, to my Sent folder.

Cannot add Outlook acct. Found settings automatically - OK. Error: cannot authenticate. Addy has 3 "-" between 3 words - possibly problem Two other Outlook's fine Tried Windows 10 & 11 boxes both fail. Manual config fails. Tried smtp with "." and "-" before "office365.com"

I have 3 computers. Two are running Windows, and one is running Linux. I was pleasantly surprised to find that Linux Mint has Thunderbird built in. I keep the two Windows computers in sync with a file compare program, "Beyond Compare" Are my local folders compatible between the two operating systems so I can sync my Linux Thunderbird local folders with the ones I have stored in Windows Thunderbird local files?

Are txt files stored the same in both NTFS and ext4 systems?

Hi! I am having an issue with displaying sent mails. As you can see in the screenshot (cropped for privacy), I have selected the option to "Place replies in the folder of the message being replied to", which to me means that eg. a reply I sent will both be shown in the "inbox" folder in the message thread, as well as in the "sent" folder. However, it only shows up in the "inbox" folder. Why does this not work?

Thanks!

On T-Bird start up I'm given a list of (originally) four Profiles. Currently I only use Profile Three, but on start=up today it is not there. Doing the usual searches does not list it, only 'default', 'new user' and 'profile two'. Is there any way to recover it?
