Thunderbird Support Forum

For some reason, my Thunderbird recently "updated" to version 115.10.2, and the "About Thunderbird" dialog says that it is on the "esr update channel." I can find no information about the esr channel. However, when I start Thunderbird, it displays the "Welcome to Thunderbird DAILY" screen. Am I correct that this is an error? If I were really on the daily channel, I think that the version number should be higher.

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

There are many answers to the question of how to disable message threading. All are from earlier versions than mine, which is 115.7.0 -- as witnessed: Sorry! 0 results found for ‘disable threading in version 115.7.0’ for ‘Thunderbird'

Thunderbird seems to have so many minor changes and alterations in the recent past, that basic usability is affected. Not a good thing.

Once before, a few years ago, Thunderbird got so out of control that I had to go to a different mail client. Are we back to that?

How can I turn off the threading of my emails? Its driving me crazy as when an email comes in after a short time it disappears into the threads and then I have to open each thread to find out who sent the email. At one stage there were 6 emails noted near the inbox but no new unthreaded message, all went to respective threads. Very time wasting.

In general, I like Thunderbird, have used it for years. But if there's one thing that will make me abandon it it's that incoming links are not hyperlinks, they're just text. From what I've read, that's deliberate. If not, how do I make incoming links be links? I'm really ready to move on.

Need to set up Thunderbird to receive emails from yahoo. Cox is transitioning emails to yahoo presently have two addresses : cliven@cox.net and daciaandclive@cox.net

as from the 19/2 the emails are not coming through also It would not send emails if you can help you can email me back on thevrons@hotmail.com.Thankyou Ron Turner

I have been using three email accounts on Thunderbird, all for a long period of time, and all without any issue. Recently the one listed below has not been backing up, and I receive this message. I am not techie at all, so any response needs to be dummy down to a 5th grader level. Thanks!

"Non-overridable TLS error occurred. Handshake error probably the TLS version or certificate used by server mail.q.com is incompatible."

I recently archived locally about 10 years worth of emails successfully (the emails were removed from the my ISP's servers and I opted for a yearly format). I can easily find these in Thunderbird but of course they are not on the mail server anymore.

Settings info: I have Message Archives set to "Archives on Local Folder" followed by my email address (I set it up with this name so that I can find the archives specifically for backup by my Sinology server).

However, my Sent folder (shows a paper airplane icon) is missing, although I also downloaded it and thought it would be saving locally.

When I verified my Archive options in TB, I noticed that while I had selected "Yearly archived folders" I did not select "Keep existing folder structure of archived messages". I assume that this is a mistake on my part?

My questions are: Q1. Where are my Sent emails - would they be mixed in with received messages in each yearly archive? Q2. How do I access these sent emails within the TB search window?

Any advice and suggestions would be most appreciated and thank you. C.

Since upgrading to version 115.8.1 I get unable to write email to mailbox . I have three email addresses in my profile. All are POP. One (from yahoo) always hangs and the other two fail intermittently. OS is Windows 10 64-bit at 22H2 level It doesn't matter if Zonealarm is turned on or off. I have over 300GB of free space on disk.

Full error 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.

Suddenly, I can't send email from my Thunderbird (115.6.1 (64 Bit)) Windows app. Spectrum is my email provider. I can receive email just fine. However, when I respond to an email and when I send a newly created email or replying to a receive email, I get the following error message - " Sending of the message failed. An error occurred while sending mail. The mail server responded: <[edited] @tx.rr.com> sender rejected. The email address you are sending as must match the email address you used to auth. Please check your SMTP settings. AUP#Out-1500. Please verify that your email address is correct in your account settings and try again."

I've been using Spectrum and Thunderbird for many-many years. This problem is going to cost me big-time if not resolved soon. I love THUNDERBIRD!

Please help!

My email address is - [edited] @tx.rr.com [removed phone# from public]

With the moving of Cox emails to Yahoo would it be feasible for Thunderbird to put an instruction list(with screenshots) of how to get all our TB email accounts from Cox to TB? Do we have to delete all our TB email accounts and re-enter them into TB under the new Yahoo or can we just change the server settings on the existing Cox settings? If just changing server settings what are the settings for the new yahoo? All my accounts are IMAP so if instructions could be made, maybe one for IMAP and one for POP for those who use either. Thank you

I've just now noticed the Threading automatic default grouping/marking of messages, and it is appalling. Thunderbird/Mozilla either needs to eliminate this (with appropriate warning notices, perhaps) or at least give us the ability to NOT link various messages. It's not only vastly annoying, it can cause severe real-world problems if anyone not in the CC or BCC fields is receiving these messages that were not intended for them.

I suppose for now, the only way to NOT link things that were never meant to be would be to change the Subject when discussing important topics.

Either that, or get a whole new mail service, which I'd prefer not to have to do.

Hello,

I run a. Thunderbird v 78.14.0 (64-bit) on a Macbook Pro 13"mid 2012 with Mac OS 10.10.5 (Yosemite) b. Thunderbird v 115.5.1 (64-bit) on a Macbook Pro 15" mid 2012 with macOS 10.15.7 (Catalina)

How do I make happen, that I sync the calendars in both Thunderbirds constantly, i.o.w. instantly (like for example the iMAP emails do)??

I find the option for new calendars: "On the network" ... Which network is here meant??? In the help there is not much info about it. I am not using and will not use Google or any kind of "social media" (!)

Can I use my own homepage host (which has some webspace left) in order to sync? Or for example an online storage like mega.nz ?

Or could the both macs just sync the thunderbird calendars just via WiFi/WLAN directly (AirDrop ?) or via Bluetooth ??

It would be so great if calendar sync would be as easy as the emails do!

Thanks for you advice!

Best wishes, Thomas
