Att made me change my account password. Now Thunderbird cannot access messages. I have entered the new password in out going and incoming but there seems to be more to this than that because nothing happens. Where do I have to put in new passwords? Thanks so much. Marjorie

Hello, I'm using the most recent version of Thunderbird on a desktop using Windows 11. Just this morning (Aug 11), all incoming email to all my four accounts are coming in with no subject or correspondents showing and when opened the email is not formatted in HTML, just plain text and lots of code. I have tried several fixes with no success: repair folders, turn off all add-ons and anti-virus protection, uninstalled and reinstalled software. Can you help, please? Thanks!

why just today is all my incoming emails coming to trasha nd not my in box in Thunderbird worked fine in the morning but i am not getting any mail in my in box it is all going to trash

I used to troubleshoot when Thunderbird would fail to download new messages by looking at the last successfully downloaded email. But I can't find the error log. I'm pretty sure older versions allowed you to see the error log under Tools. But it isn't there and developer section is not helpful. I have tons of message filters going into folders so it is impossible to identify the last successful email download.

How am I to fix this issue if there is no longer a way to see failed email downloads via the error log?

I wasn't happy with the UI changes burying the menus into the hamburger on the side, but figured I could live with it. Not sure the benefit, maybe it looks cleaner? But removing functionality at the same time is really NOT helpful.

Anyone have any ideas how to find the error log or find the email causing Thunderbird to stop seeing downloadable emails?

When sending an email using the keyboard shortcut, the settings tell me that I can set TB to give me a confirmation prompt. Why can't I get a confirmation prompt when using the Send button? Is there any way to make TB do that?

I set TB to run a spell check before sending, and that gives me an opportunity to cancel the Send operation. But it only works if the email contains a misspelling.

Thank you.

I can not send out emails from Thunderbird. I get the following message "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.xxxx.ca timed out. Try again." I have not been able to find an answer to this problem. I hope you can help. Please note I am a Senior so please be patient with me. Thanks, Al

The Reply command no longer shows when I want to send an email back to the person that sent it. There is a note at the bottom of the email that says: A unique identity matching the From address was not found. The message will be sent using the current From field and setting from identity Vince Hunter < omni232@telus.net> Can you give me instructions in laymans terms to fix this bug and return it back to the way it was?

I can't access an MSN.com account, but I managed to do so with two other accounts. I've already deleted it twice and tried again, and the password is correct. Can you help me?

je n'arrive pas a accéder a un compte msn.com pourtant j'ai réussie avec 2 autre compte.j'ai deja supprimer 2 fois et réessayer et le mot de passe est correcte. pouvez vous m'aider ?

This just started happening today. The last message to come through normally was today (August 11) at 10:20 AM EST. Every other message today after that time came through as described in the subject of this post.

I am running Windows 10 Pro version 22H2 fully updated through the July 2025 updates. The Thunderbird version is 141.0 (64-bit). No new Thunderbird add-ons have been installed.

The columns for Subject and Correspondents are there, but they are blank for all my messages after 10:20 AM. The message body is like I said—it looks like I selected View|Message Source. I have both of my email accounts for Optimum and Gmail on Thunderbird. Optimum is POP and Gmail is IMAP. The Gmail message that I received a few minutes ago looks normal. The messages accessed on my Optimum webmail account look fine as well so it looks to me to be a Thunderbird issue.

I have tried the following:

1. Repaired the Inbox folder within Thunderbird.

2. Restarted Thunderbird in Safe Mode.

3. Exited Thunderbird, deleting the global-messages-db.sqlite file in my profile folder and restarting Thunderbird.

4. Exited Thunderbird, deleting the Inbox.msf file in my profile folder and restarting Thunderbird.

5. Reviewed all the Thunderbird settings—they looked OK.

6. Rebooted my computer.

7. Uninstalled Thunderbird via Control Panel|Programs and Features, then downloaded and installed the current version of Thunderbird from the official website.

I have uploaded a screenshot of what my Thunderbird screen currently looks like.

Thanks for any help.

At lunchtime today I started getting emails with no header sender or other info. It is just blank and the emails dont show just a load of source info in the message body.

Hi. First off, a BIG thank you for all the hard work you have put in and now give it to us for free to use. Your generosity is mind-blowing. I am using TB on Linux and Android. My email life depends dramatically on the use of aliases. When I send mail luckily TB let's me "customize the from address" and I can use anything my email provider allows me to use. That's fantastic. But there is a bug. When someone replies to my email and I hit reply to answer their reply, TB PUTS THE WRONG EMAIL ADDRESS INTO THE FROM FIELD. It puts the main email address, not the aliased address the email I am replying to was sent to. Once I did not pay attention and hit send - and my cover was blown. My main email is for no one to see, just the aliases. Please, PLEASE fix this bug. When replying to an email, the from should ALWAYS be the address it was sent to. This is really important and if you fix this, as far as email goes, my life will be perfect.

On the Android version,, things are much harder. Itis impossible to compose or reply to aliased emails so I can only use it for reading.

I believe that if you fix the alias issues, for people whose email provider allows aliases, email usage patterns will truly be revolutionized. Thank you

I have made 3 attempts to add a thunderbird account to receive email from an old verizon.net account server. All have failed.

All three times, I got the message.

     "Unable to login at server. Probably wrong configuration"

which is a remarkably ambiguous error message. It takes about 10 minutes for that message to appear.

I am able to log directly/independently into what I understand is the verizon server. But obviously I am doing something wrong.

Independently, I successfully added a thunderbird account for an outlook.com.

I will skip the verizon account for the time being. I have one other account to move the Thunderbird.

I successfully moved all three to Mac mail a few weeks ago, only to discover that I really don't like it for a variety of reasons, the most significant for me was that

     - I learned about IMAP
     -  I couldn't delete messages, although IMAP on a mac creates the 

illusion that I could.

There is nothing quite like seeing messages that I know have deleted, reappear marked as unread, right before my eyes.

Thoughts anyone?

I keep getting this message "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox." every time I log in, try to delete an email that has already downloaded, and every time I click get messages to download messages.

No messages have been downloaded since two days ago. I did go on the web version of my email and deleted all emails from that time period in case there was a virus so it's not that. I strangely started when I ignored the compact folder message sever times. I did however try to compact the folder from the file menu, as well as cleared the cash and emptied the trash.

I made sure I had the latest update as well. I am thinking the software is corrupt at this point.

Dzień dobry mam konto na poczcie Thunderbird. Od jakiegoś czasu mam problem z wysyłaniem wiadomości jest informacja ze przekroczono limit wysyłania. Sprawdziłem wszystkie ustawienia poczty wychodzącej serwera, powyłączałem zapory, antywirusy usunąłem pocztę i zainstalowałem ją z powrotem i wiele innych rzeczy nie mam już pomysłu jak to rozwiązać jak zmieniam z wi-fi na router w telefonie to wyśle mi jedną wiadomość a potem znowu mnie blokuje. czy jest możliwość zdalnego połączenia się z wami żebyście sprawdzili co się dzieje z tą pocztą.

Failure to download email from Optus. I have spent a number oif hours to no avail talking and typing with the Optus staff regarding this problem. 1. I can send email from TB but cannot receive. 2. I can see the incoming emails in their Webmail site. 3. Optus confirm my settings are correct for both the mail server and SMTP server. When I go to Settings> Security > Passwords > remove server so I can re-submit my password, the only one showing is the SMTP server. Should the incoming mail server also be shown?

I am frustrated and ready to dump TB but have bee with it many years and don't want to start again with another programme as I am 83 and am partially blind. Please can anyone assist?
