Thunderbird Support Forum

I am currently on Thunderbird v115.5.0. Ever since v115 came out I am unable to make my Inbox stay unthreaded. I set View / Sort By / Unthreaded and it works for a while, but periodically when I delete a message, move a message, or a new message comes in the Inbox reverts to Threaded view. This is absolutely maddening, as I have to repeat this many times each day. Can anyone tell me how to make Unthreaded view stick on my Inbox? I'd like to stick with Thunderbird, as I've been using for almost 20 years, but I simply cannot continue to waste so much time on it.

This problem has been reported before, and I've done web searches and searches in this conference, and none of the solutions work.

I'm running 102.15.1 (64-bit) on two Windows 7 systems. On one of them, something has gone wrong. I accidentally clicked on a .themepack file and the theme didn't work correctly afterwards. I eventually got to a point where I could access Personalize and go back to the previous theme. The system appeared to be working after that, but as a precaution I went back to a system restore point from well before this event happened. After that, everything on the system worked correctly EXCEPT Thunderbird. When I start it I don't get any errors, but it's all blank. The menu bar is visible, and the get message line, but the folders panel and the panel where there should be mail messages are completely blank. Pulling down "Tools" and selecting "Settings" does nothing. Oddly, I can access "Account Settings", and they look o.k. I can also pull down "Help" and get the Troubleshooting information, and it pointed to the correct profile. I don't see how changing themes could be the actual cause of the Thunderbird problem, as everything else on the system is working but I mention it because I had to do a shutdown and reboot and let the system force Thunderbird and other programs to stop.

I have tried all of the fixes I could find in other notes, and none of them worked. Changing the name of global-messages-db.sqlite and restarting didn't help. I can start in troubleshooting mode and disable add-ons, but that doesn't help, and I don't have instructions on what to do once I'm in trouble shooting mode. I also tried starting it with -safe-mode, which also didn't help.

So I tried brute force. I de-installed and reinstalled Thunderbird and convinced it to use the old profile, but that doesn't work. I finally de-installed Thunderbird and used RevoUninstall to make sure everything in the directory and all folders and files were removed. I then copied my profile from my other working system (both Local and Roaming), did a clean install of Thunderbird, used the profiles that should be good as they were from a system that is still working, but even that hasn't fixed the problem. (I've copied the profiles between systems before at least twice and got them to work, so I'm reasonably sure I copied them correctly this time).

I can't imagine what else could possibly be keeping Thunderbird from starting correctly. At this point I'll accept any suggestions or even wild guesses as to what I should to do next. I have a lot of my mail stored in folders, and I'd really hate to have to redo everything from scratch, especially as I should be able to copy profiles as I have done before.

The ability to change font size is disabled. I lost my User profile on my PC, and I am starting from scratch with all settings. My custom folders are still there, but I have had to recreate message filter rules, and I can't get the font large enough to read.

Note: When I click on the image I provide below, it makes it look like my font size is huge. It is not.

i am getting encryption every time i try to ope something in in box please tell me how to disable this . it is greyed out in Thunderbird can not change it . please help me i do not wan encription a want to remove checkmarks but can not it is greyed out

I have two separate Thunderbird email accounts, one which shows Local Folders in the left folder pane and one doesn't. When I select "Hide Local Folders" on the account that doesn't show that folder name, all folders, Inbox, Sent, Junk etc disappear from view. I need to change these two accounts prom Pop3 to Imap but keep the Local Folders for filing read emails but am concerned that when I delete the Pop account I will also lose all my previously saved emails. It appears that on one account all of the folders are acting as Local Folders although the top header is my email address and not "Local Folders"

Any help would be appreciated. Thanks

I am trying desperately to avoid going back to windows, but you are not making it easy!!!!! If i may say so, you run this like it was a private club and i am not in it! Ticket 127190--how do i find it? How do i see my previous requests? I could use some compassion here!!!! Bring on the kindness....b3 Thank you for reaching out to us. We’ve received your support request and opened a ticket (127190). We are processing your request.

We appreciate our subscribers and will make every effort to get back to you within 2 business days. I would like to think that my problems are more due to my own stupidity than TB, either way, i still need help!!!!

Hi All,

Just reporting in. Win7 OS.

Still getting roughly 1 Thunderbird crash per day ( 115.4.3 ).

It always seems to be when TB has been out of focus and I call it into focus. The entire GUI dialog box is white.

Thank you.

linux mint cinnamon victoria, thunderbird 115.5, email provider runbox.com, is there a simple way to toggle b/w light and dark themes please? Thank you....b3

I'm having a lot of trouble setting up a functioning second e-mail account in Thunderbird. I've tried numerous times and it either doesn't show up or if it does, it won't receive or send. I wonder if part of the problem is the settings provided by my ISP. Thunderbird fills them in automatically, but they're not the ones my ISP wants. Both the server name and the ports are incorrect. I try to change them manually but then the 'continue' button is greyed out and I'm stuck. Using the ones Thunderbird wants doesn't work, I can't send or receive. I need it to be a POP3 account, my ISP gives us very limited server space.

When I set up my initial e-mail account the automatic settings were correct to what my ISP wanted, so there wasn't a problem. Any help would be appreciated.

I have used Thunderbird for years. I have never had any issues until now. We do love the product. The last update messed up my incoming on one of the accounts. The account is: tony@action-av.com, under this account it shows I have messages as they come in they populate the messages but I cannot see them to read them at all. I can only see old messages. Please only email me with help on this address that still works that is tony@actionkravmaga.com it work perfectly. tony@action-av.com does not work whatsoever. I can't organize the incoming in by date or by attachments or by if it was read or not read. It shows I have 200 emails but I can't open them because they don't exist within the window. They only exist by the account name of unread messages. Within the window I cannot find the incoming messages whatsoever but it does change the number by the account of incoming messages. This all happened after the last update I don't know if it was corrupted in the process of receiving it and it's just not working. I looked at the area to update it to the old one or even doing the new update too. But it kept on saying that it's updated and I cannot do this. It will not allow me to update whatsoever it says my update is up to date. I was looking at possibly putting the old update back in but I tried to do that and it did not work. If you want to give me a call. My phone number is [removed email from public support forum]. My name is Tony McKenzie. If you do email results of how to fix the issue please email them to [removed email from public]

I've been using TB for years and years but this is the end. It was originally a nice alternative to Outlook Express with a small footprint but now it's decided that half my client list is spam. I have literally lost business because emails keep going into spam despite me marking them over and over and over as "not junk".

this is absolute BULLSHIT.

I have Thunderbird 115.4.1 as of 2 days ago I have been unable to send any emails. I have Spectrum as my ISP and the error message I get is:

Sending of the message failed. An error occurred while sending mail. The mail server responded: <lzweig1@san.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.

None of my settings have changed in years, and all of a sudden I cannot send any emails. I have talked to Spectrum and verified that all my settings are correct. All they tell me is that I need to contact Thunderbird support. I can receive emails just fine, just not send any from any of my Spectrum accounts. If I use the Spectrum webmail service everything is fine. But all my emails and address book are in Thunderbird and I would like to continue to use Thunderbird as my default email client.

Please help, Larry

I am running Thunderbird 115.5.0 (64-bit) on Ubuntu 22.04.

I have two accounts with email MS - one with Hotmail, and the other with Outlook.

Both continue to receive emails without issue.

Recently, neither can send emails - having been able to send emails for years.

They had different SMTP servers, so I checked to see if I was using the correct server, and both appear as being correct.

I tried adding one account (again) to ensure TB would select the correct server, ... and it still cannot send emails, but still receives emails.

I have tried both with oAuth for the password, but that has stopped working.

I can find nothing online, and feel like I have exhausted the internet for solutions, so if anyone can help, it would be most appreciated, as I am sure others will be as frustrated.

Many thanks,

Setting up the Thunderbird after installing and making a donation.

Disappointed to find version 115.4.1 will no longer sync messages from a Gmail account it's been syncing from for the last 4 years.

I've removed the account and restarted from scratch. All messages appear for 1 or 2 days, then it deletes all the messages from 3 days ago to 2018, six years ago.

The messages are still there on the Gmail folder. I can see them on my other devices. It's just that Thunderbird refused to pick them up.

Can I get my donation money back? This seems like a bit of a joke.

An email will be sent with an attachment. If another participant replies to it, the original email disappears, but then appears in the chat history of the reply, but the attachment no longer appears. It still exists on the server. How can I prevent the attachment from disappearing?

Ever since upgrading to Thunderbird 115 forwarding email does not work consistently.

I get this error very often

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Timeout - closing connection.

I have reinstalled Thunderbird on a computer which was experiencing a Microsoft Windows 11 problem. My local technicians reverted my computer to Windows 10, for several reasons. Suddenly, I can no longer see the attachments in emails that I know have attachments. How to fix this?

I have supported Mozilla/Thunderbird since it began its existence, but if this problem persists, I will have to give up on it. If anybody can help, please help! mnylan@berkeley.edu
