Thunderbird Community Forum

My name is graeme , my wife Olivia.

I have many many messages from various people; if I reply to a a mail from "fred", Thunderbird creates a mail:

to: fred@xxxx from: graeme@xxxx

I have several messages from my wife , that behave in this same fashion (ie , as you would expect) but ONE message, when I reply the message displayed in Thunderbird (ie NOT YET SENT, so no SMTP etc yet involved) says:

(it does NOT have a REPLY-TO header BTW)

to: graeme@... from olivia@.....

...I've search back though my mailbox and all the mails from my wife work as you would expect, bar this one ...AND ONE OTHER that I found:

This says:

from olivia@.xxxx to: company@xxxx, olivia@xxxx. graeme@xxxxx

When I hit reply , it generates a message:

from olivia@xxxx to: company@xxxx, olivia@xxxx. graeme@xxxxx

So the from and to in the reply are exactly the same as the from/to in the initial message (they are not swapped)

So, to be clear 99% of messages are fine, it's just one or two cases where I get this odd behavior.

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!

My Sent folder disappeared. How do I restore the folder with the sent messages still intact. Or, at the least, just restore an empty Sent folder. The In-Box, Drafts, and Trash are still there.

All the settings are correct, and it seems that because there's no Sent folder I cannot send an email. When I try to send a message I get the attached Error.

My local phone company routes email through Yahoo Mail, then to Thunderbird. It was all working fine until my Sent folder disappeared. Now because of the missing Sent folder I have to create the email message in Thunderbird saving it in Drafts so I have a record. Then, I have to copy it and send it from Yahoo Mail. Needless to say this is a pain in the you know what.

Can someone please provide the instructions to get my Sent folder back?

Thanks,

Tess

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

I have a problem with creating a new message. The "new message" icon or the keyboard shortcut from Windows does not work. The problem was in version 133, today's update 134 did not fix it. I have to edit an old created message/email and send it.

Running Thunderbird with three accounts on my desktop PC - two 'btinternet.com' accounts and one 'gmail.com' account. Inboxes have no more than 20 emails in them, as I delete unwanted ones and transfer others to various sub-folders ( In excess of 40 No.). Today I suddenly found that incoming emails on both bt accounts were not showing the subject or sender and the content is displayed in plain text (txt) format - no problem with the gmail account.

I have compacted and repaired the inbox folders but no difference. If I send a message from either of the bt accounts to the other the problem occurs, but if I send a message from either of the bt accounts to my gmail account, it goes through fine. I can receive bt emails fine on my laptop. I assume this is a thunderbird problem on my PC but not sure where to start - would be really grateful for any guidance.

I have added the android app to my phone and tablet but the messages are not synchronising fully with the version on my windows laptop. The 'sent' messages from my phone / tablet do not appear on my laptop although 'received' messages do. 'Sent' messages using the app do not appear in my Gmail linked account either. Any advice would be welcome please, it's a bit of a hassle having to keep checking things on separate machines.

Thunderbird not displaying all new emails in the inbox. New emals are downloaded and visible in all other folders.

Problem started 2 days ago.

Checking on my cellphone using Google chrome on my webmail account new emails are shown.

If I quit Thunderbird and restart the new emails now show in the inbox.

What needs to be done to get All new emails showing up in my Thunderbird Inbox?

Hello, My thunderbird is displaying the following message when I forward an email. "An error occurred while sending the mail. the server responded the "name file.eml" attachment has been dissallowed extension". This error also occurs if the message you forward does not have attachments. my account is configured with pop. How can i solve the problem .

thanks

I have been using Mozilla Thunderbird for decades and they have even contributed a small amount of money to Thunderbird periodically. Just within the last two or three days all of a sudden I have been unable to send emails with my phone. I receive emails, but I do not send them.

So I opened up a laptop where I did not have Thunderbird and set it up properly through Spectrum using the incoming and outgoing servers as mail.twc.com. and yes, just like on my phone. I continue to receive new emails, but even with the laptop I was unable to send an email.

I received the message"send message error sending a message failed. The message could not be sent because the connection to outgoing server smtp mail.twc.com was lost in the middle of the transaction. Try again."

I contacted Spectrum twice and both times they had me try to send a message through their Web server spectrum.net and that message did go through. Of course then their response is that this has to be a problem with the third-party app meaning Mozilla Thunderbird, and they can’t help with that at all. I sure would appreciate some help because I hate to walk away from Thunderbird as well as change my email address after all of these decades.

Hi there I have recently started using Thunderbird again on my iMac and have noticed when I send a email using Gmail the sent email is showing in my sent folder on my Gmail account but is not showing in the sent folder on Thunderbird the only emails in my Thunderbird sent folder are emails I have sent using Thunderbird any emails sent from devices like my iMac or iPad are not showing up in the sent folder on Thunderbird.

I am not sure why this is happening any help would be much appreciated.

Since awhile while, the items I send, don';t show up in the sent folder of that account. The complete folder is empty, which means that I also lost messages. I didn't make any changes to the settings, it might have happened due to an update maybe?

My other accounts work still fine. I checked all settings I could think of that might affect it, but haven't found a solution. I'm getting pretty desperate and hope someone can help me out.

It's an IMAP account. I've selected the 'sent folder' in subscribed. 'When sending messages, automatically' the 'place a copy in' is checked and directed to the email address. Also tried it with checking 'other' and select email address. I also just tried to 'local folder', but nothing happens.

I hope my description is fine. If more info is needed to tackle this problem, I like to hear!

I've used TB successfully for many years to access several Yahoo and Googlemail accounts. Windows 10. Recently the Yahoo accounts don't work so I've tried several times deleting and reloading them. This may be a red herring but the trouble seemd to start when I installed TB on a new Windows 11 laptop and failed to load the Yahoo accounts. I've tried following both Mozilla and Yahoo help articles but ultimately success is partial at best (i.e. incoming works, outgoing fails) This is the sequence I have followed

251128 tried this: Deleted all yahoo accounts in Thunderbird

Edited outgoing yahoo server to

 smtp.mail.yahoo.com
 Port 465
 SSL/TLS
 Authentication method OAuth2
 User name johngherrett@yahoo.com

Added yahoo account johngherrett@yahoo.com name and email address

opens yahoo! login sequence enter email and yahoo account password - FAILS

logged out of Yahoo mail open elsewhere

Accept 'Configuration found in Mozilla ISPDB'

opens yahoo! login sequence enter email and yahoo account password - FAILS

followed guidance from Mozilla article: https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo Exit Thunderbird Wait a few moments for background process to complete Start Thunderbird

counted to 10+

restarted Thunderbird Yahoo account is not there Googlemail account is there - OK

'Set up another account' - email started again Name & email

Go to https://help.yahoo.com/kb/sln27791.html Login to yahoo account 'Ways to securely access Yahoo Mail'

Use an app password ************

Signed out of a 'current sessions' even if not recognised. (Except 'current device' which is the login just past.

External connections-> Create app password App name : Thunderbird Generate

Copied to clipboard ********************

Returned to TB

entered password 'Continue' Spinning icon and re-opens yahoo login dialog entered normal password 'Something went wrong'

entered app password 'Something went wrong'

Despite this, after closing the yahoo dialog, TB says 'Account created successfully'!!!!

Inbox appears

Note:server settings now set somehow to IMAP / normal password

Testing outgoing: Message fails, Yahoo dialog login fails Edit outgoing server which remains OAuth2 Changed to normal password

Tried app password - failed Tried normal Yahoo password - failed

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?

Any thoughts on this will be very much appreciated. I have 2 email accounts with Yahoo and am using Thunderbird to access them. It used to work properly, but now I can receive emails on both accounts, but can only send emails on one of them. The other account gives me the error message: "Sending of the message failed. An error occurred while sending email. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again." When I then look at the SMTP user name, it shows the name for the other account. When I change that user name to the correct name, I can then send emails on that account, but the process also changes the user name in the second account, such that it no longer allows sending emails. In other words, when I go to 'account settings' and set the SMTP user name for account 1, then go to account 2 settings, I find that the account 1 user name shows up. If I then change the account 2 user name and go back to look at the settings for account 1, I find that the SMTP user name in account 1 has changed to the same as I just changed in account 2. Additional info: Prior to this problem, I had gone into my emails on the Yahoo website and changed the password on both accounts. When I then opened Thunderbird it asked me for the new passwords for each account, as it normally does, and everything looked fine until I tried to send using the one account. Thanks for any thoughts.

As of today, I can neither send nor receive email for my imap accounts - imap.gmail.com and imap.mail.yahoo.com. I have Thunderbird 128.9.1esr(64 bit). They both work outside of Thunderbird. Notification reads: Authentication failure while connecting to server ... where ... is each url above.

This was working ok until today. Now, only ONE of my mail accounts is sending mail to the "All Mail" folder as "Unread" and NOTHING is going to my Inbox. Anyone have an idea what could be causing this?
