Config editor has no printer listed. nothing to reset. Printer works with other applications just not TB. Re-installed the printer. Reset the space limiters, which I found were set too low. Restarted TB and computer

Some of my contacts have passed on. Others are dysfunctional. Whenever I delete the address in the address book, the question comes up: do you want to delete? If I click 'yes', nothing happens. even if I delete the email via editing the contact, the email is restored again. I use Linux Mint 22.

Hi, I've set up TB successfully on a new PC and been using it a while. Then I noticed my local folders archive group of subfolders was missing. I followed some instructions about moving local folders file across from the old to the new version.

Now I see the individual archive folders without the folder group name 'archive'.

Also, there are a couple of other files not visible on the new platform although they were in the original installation local files and were copied across.

I was careful to ensure the same version running on both PCs. Also that TB was closed when copying files across.

Any pointers appreciated!

Jeg har skiftet adgangskoden til min mailkonto hos min udbyder. Jeg har angivet koden og opnået adgang til indgående post. Hvis jeg vil sende en mail nægtes afsendelse. Jeg bliver bedt om at angive den særlige kode for udgående post til asmpt server. Den anden kode virker ikke. Jeg skal have koden som giver adgang til at afsende post.

I'm brand new to Thunderbird. I have set up a Yahoo Mail account in Thunderbird and have no problem receiving e-mails via this account.

However, when trying to send a message from this account, if, under Account Settings, I insert a Reply-to Address I get this error message: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please check the message and try again."

If I delete the Reply-to address either in Account Settings OR in the e-mail I am trying to send, the message goes ok. This does not happen with another, non Yahoo, account I have added to Thunderbird.

I'm lost as to why this might be and any helpful ideas as to how I can overcome the problem would be very welcome.

Is it possible to open incoming mails in the same window as the list of e-mails, just like in Google? I get distracted from seeing suddenly my e-mail in another window/tab.

Thank you!!

Ich bekomme ständig folgende Aufforderung: Authentifizierung erforderlich - Mozilla Thunderbird https://spica.t-online.de verlangt einen Benutzernamen und ein Passwort.

Just updated to latest Thunderbird version and now I can't send my email. I keep getting the message "Login to server smtp.broadband.rogers.com with username [my email address] failed."

Then when I exit this notification, the following shows up "Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'."

I made not changes afer in upgrade of Thunderbird to latest version.

Any help you provide would be appreciated.

I have a number of accounts setup in Thunderbird, some are gmail accounts and some are Yahoo accounts.

After the last Thunderbird release one, a couple days ago, of my Yahoo accounts stopped working and wanted me to authentic it. It pops up with a Yahoo window to login. I tried to login with my username and password which didn't work so I went into Yahoo and created a new app password and tried that. It won't work either. I just get the message, something went wrong.

Then my other Yahoo account stopped sending out emails, just get a connection timeout message. Now my gmail accounts won't send out emails either. I can receive incoming emails, but not send out emails.

This is the message that I get when trying to send out an email now:

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again.

I have searched and checked that my Outgoing server settings are correct for both Yahoo and Gmail. I have a different outgoing server for each email account and they have different unique description names. Cookies are enabled, accept cookies from third-party sites is set to Always. I had Auto-detect proxy settings, have now tried No Proxy.

I am using Microsoft Defender for my virus protection.

This is how my Outgoing Gmail SMTP settings are set: Description: Gmail - xxx@xxx.com Server Name: smtp.gmail.com Port: 465 Username: xxx@xxx.com Authentication method: OAuth2 Connection Security: SSL/TLS

This is how my Outgoing Yahoo SMTP settings are set: Description: Yahoo SMTP - yyy@yahoo.com Server Name: smtp.mail.yahoo.com Port: 465 Username: xxx@yahoo.com Authentication method: OAuth2 Connection Security: SSL/TLS

Any ideas of what else to try would be greatly appreciated.

Thank you

When trying to send a message via Yahoo Mail I get this error message: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please check the message and try again."

I have no problem receiving e-mails via Yahoo.

I have another account set up under Thunderbird with a different e-mail provider and that works fine for both sending and receiving. I have tried various things but am at a loss as to what the problem is.

I FINALLY was able to find the original profile, all messages in the In Box, plus all folders with their contents. 'Lost' when our ISP's ' tech support person ' had me close/remove the TB POP3 account and create an IMAP account).

I need to merge the new small profile (In Box & with basic folders) into - onto the BIG, original, profile. So each time I get/check mail everything goes to, ends up in, the Thunderbird account containing all the OLD data and new working account.

Please remember I am barely TB literate, so start at 1 (A), not 27 (Z)& no tech words. Nor acronyms please.

Thanks! Remain in GOOD health, be WELL, 'n be

Can anyone tell me how to set up the THUNDERBIRD TO ALWAYS LOG-IN into its own Messenger and avoid the Yahoo's interference with his INADEQUATE Messenger format - this should not be high-science question but I have difficulties to find an information in the HELP-section - thanks, Tony H. ...!

When I remove a Quick Filter, I'd like the list to move to the most recent message (my msg lists are sorted by date desc). Instead what happens is that after showing the full list, which includes redrawing the list so that it moves to the top, it forces the re-selection of the message that was selected when the Quick Filter was in place. What happens, a lot, is that after checking a message via filter from months ago, the filter is released, the full list appears briefly, I select the top message if I'm quick, and then it re-selects the message from months ago. I then have to scroll to the top or use ctrl home.

It's very stubborn about this behavior. Even if I

• select another email account which would not contain any hits for the filter
• wait for it to build that list
• select an email at the top of that list
• select the All Accounts top level Inbox folder

it will re-select the email that was selected when the filter was in place.

I filter a lot and each time I have to fiddle around with this to return to the top of the unfiltered list, which takes time.

It seems like a rather lame behavior, not sure if it acts like this by design or not. But it be better to at least have the option to have thunderbird go to the first message in the list. By the time the Quick Filter is released, doesn't it make sense to return to what would have to be the normal selection for most users, the top of the list?

OS: Linux Mint 22.1 Mozilla Thunderbird 140.4.0esr Junk Mail Header: SpamAssassin

It has been stared around a week ago, Thunderbird gives notification as any spam email arrives. Although those spam mails are accordingly redirected into the spam folder, also marked as spam well, but the user interface and the audio notification still come though.

This behaviour is unlikely Thunderbird used to act, in my computer, and I've been using it for years. I haven't touched any setting for months. It just started doing this like out of the blue.

It's a non Gmail account, so no provider spam filter. Is there a solution for this?

As of 10.8 I have been able to send but not receive emails from my AOL account, which now has 650 emails sitting there waiting to come into my Tbird. Assuming it's a problem with the pop server settings, and last time an AI-generated password did the trick (but done by tech guy not I). I cannot seem to reset the password to make it work and would be grateful for any suggestions. I've made an external backup of the whole default profile just in case.

(115.18.0 (64-bit); POP3) Cannot delete folders from app or profile & "About Profiles" shows the wrong profile. This started when I simply attempted to rename a folder in Thunderbird, and emails disappeared *remain in old folder. QUESTION: Can I safely simply set the correct profile as the default (lojbsrwp.default)? ISSUES: -Troubleshooting information shows incorrect profile Roaming/Thunderbird/ (no files since 2017); Settings shows path to correct profile. -Two Profiles showing in /Thunderbird; one appears current. -Profile show folders that do not appear in Thunderbird -Folders w/numbers at the end of file name keep duplicating when I delete, but don't disappear from either -Thunderbird & Profile. Can't delete multiple, duplicated folders. Folders with end-numbers don't match between Thunderbird and Profile. -Troubleshooting information/About profiles/Current: Root Directory & Local Directory show incorrect profile. -Troubleshooting information/About profiles/DefalutOLD: Root Directory & Local Directory shows current profile in use.

I am not sure if this is the correct place to ask my question. Apologies if you think it should be somewhere else in Thunderbird Help.

My old W10 machine crashed in September. I bought a W11 machine in October.

A colleague managed to rescue all my data from the W10 to a HDD.

I installed Thunderbird 143.0.1 to the W11 machine. On running the program it found me and my emails. I hoped it would find my wife's emails too. But no luck so far. Both domain names are the same. I've tried adding the details I have for my wife's email as a new account, but the program goes on and on looking with no result, and no end. I have to unplug the power cord to end it.

I've followed advice from the help pages to Find and restore my Profile without opening Thunderbird. In the process I've deleted the Profile on the W11 install, and substituted the Profile from the W10 install. It was around 8GB. So I assumed that Local Folders and my wife's details would show. Neither of these things occur. My account is shown together with recent emails.

What is happening? How can I get my wife's email account to show? How can I find my archive of emails in Local Folders? Any help gratefully accepted. Thunderbird 101 maybe?
