Thunderbird Support Forum

I have cox comm. for internet and emails, they just changed their server to yahoo.com. Now I cannot sign into thunderbird to send or receive emails.

I had to delete and add back several accounts due to a change in servers (cox.net to yahoo.com). Prior to this I just had the All Folders, Local Folders and below. Now I have the Unified Folders and below, which are essentially a duplicate of the folders in the old All Folders. (See attached image) Not only is it making things confusing but I'm storing duplicate emails and it seems to be affecting performance, Thunderbird now randomly quits and restarts. So, how do I delete either the All Folders or the Unified Folders and move the few sub folders that are unduplicated into the remaining group?

I have an existing Thunderbird account on my Windows 11 PC. I am now trying to open and access this same account on another PC with Windows 10.This is the message that keeps on appearing:

Unable to login in at server. Probably wrong configuration,username or password.

Any help would be greatly appreciated.

I want to turn off ALL threads in Thunderbird.

Just the last two days TWO IMPORTANT messages (from two different people) on my computer did not display in my email feed, I only saw them by accident on my phone..

I have searched very, very many times to change the settings, but regardless of what I do, it doesn't help..

I have tried "View / Sort by / Unthreaded", it doesn't work.. I have tried to look for the "Organize Mail by Thread" in Settings, I cannot find it. I have spent SOOOO much time trying to find out about this, but not been successful... (It is NOT the first time this has happened!)

Can anyone help??

I'm trying to export my Thunderbird addressbook using the export function. I go to "address book"->"tools"->"export" and I get "Export Export accounts, messages, address books, and settings to a ZIP file. If your current profile is larger than 2GB, we suggest you back it up by yourself." Then it wants to export the whole thing as a Thunderbird Profile with no other choices showing. I can't seem to export the "address book" to the "csv" format which I used to be able to. Any ideas?

Emails with different subjects are getting threaded together. For example, in the attached snapshot, why are the emails with subject "Bid S011090833" getting threaded under "Hein Revised Hall Bath..."?

Perhaps I don't understand how Thunderbird determines messages have a common thread.

Using Thunderbird 115.4.1 (64-bit)

Befor the Firefox upgrade my in box was split in two. The top half was the messages and the bottom half a preview of the message. Now I just have one long list of emails. Please can you advise how to go back to the split screen view. Many thanks. Joe

I find that when I click on links to take me to website through my email in Thunderbird that I will get an error message that reads "we could not verify the certificate, reason=wronghost"

But, if I copy link and copy into browser it works fine. There is a break in the Thunderbird email to the browser. This does not happen with all links but there are about three or four that I get regularly where it fails.

I have talked to a tech guy and we have tried different things and it always comes back to a break in Thunderbird email.

How do I fix this problem?

Thank you, Monica

How can I delete a second email account folder that duplicates data in 1st folder? Folder names are as follows: prentissr@ example.net prentissR@ example.net

Hi

Why does Thunderbird want all my personal information.......??

I'd be MORE THAN happy to make a donation to support you guys, but I am NOT happy about all the info I have to provide - and frankly I'm bot going to be bullied into giving info I don't want to. I donate to Wikipedia and they don't ask such intrusive questions - so why do you? You say that less than 2% of TB users donate - this PROBABLY the reason why they don't...!

And the fact that there is no direct link to ask somebody ask question about this subject, is really frustrating.

Thanks

Trying to add an Gmail account on Thunderbird. My email address and password are correct. What to do? Using Surface Pro 8, Windows 11. I can access Gmail account directly but something happens when I try to add it to Thunderbird. My other email accounts, outlook.com & comcast.net installed without problem.

What are the correct settings for email accounts in Thunderbird? On my new computer my accounts were setup in imap with SSL - but then changed to TLS, but I continually get this message " Non-overridable TLS error occurred. Handshake error or probably the TLS version or certificate used by server imap.actrix.co.nz is incompatible." I have a Dell Vostro 5620 laptop with Windows 11Pro. For my email accounts which settings should be correct for incoming and outgoing? Thanks - Graeme

using thunderbird, cannot send some emails- error message unablr to authenticate outgoing server (SMTP) mail.waitrose.com. I am receiving emails normally and can reply to sent emails.

I am trying to set up my Yahoo account with Thunderbird. I enter the email ad password and nothing happens. There are no popups. Just the checking password. I also tried generating an app password from yahoo and using it and it didn't work either

Please tell me how to get my address books back after moving to a new computer. I have thunderbird, and I've gotten my inbox moved, but my address books are empty. I had hundreds of contacts. How do I get them back. I've tried the import tab but it only wants to import from a file on my computer. As I understand it, my provider keeps data such as this, I just need to know how to access it. My internet provider is Optimum/
