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?

Hi, I am using windows 10 pro and i use thunderbird for my emails. Can you please tell me how i can easily backup to a usb and how i can check if its done correctly? Thank you

Strangely, I can't figure out how to add to someone else's post if it doesn't already have replies so I'm having to start my own thread. Anyway...

Thunderbird on my system is 32-bit on 32-bit Windows and a day or two ago it updated itself to version 115.10.1. Since then it's been slow at sending emails, receiving emails, applying filters and pretty much everything else. Is this being worked on? I saw a couple of similar reports from other people here but like I said, I can't add a reply to them.

And if it's not known about or being worked on, is there some way I can roll back an update?

Can someone please give me some troubleshooting tips on the Thunderbird email client on Windows 10?

I am running version: 128.1.0esr (64-bit) on Windows 10, and it started a very annoying hang / non-responsive behavior recently, and updates do not fix the symptom.

Since update to ver 128.1.0esr the "new subfolder" feature does not work (does not show window to name new folder). I have many subfolders and I rely on them heavily. I tried restarting Thunderbird, then Windows. I ran in debug mode with no success. I downloaded and installed 128.2.0esr again. No change.

Is it possible to go back to the earlier version? Which is? Thanks, Frederick

Thunderbird automatically updated to v128 earlier this week after I went to Help - About Thunderbird to check that it had updated to v115.14.

Everything seemed okay immediately after the update, but when I started Thunderbird the next day it was very unresponsive. Checking the Activity Manager showed that Thunderbird was indexing messages, but that this was happening very slowly. I let Thunderbird do its thing that day in the hope that things would settle down.

The next day when I started Thunderbird things were still bad. I tried Rebuilding the Global Database but when I restarted Thunderbird it was just as bad, if not worse.

I then turned off indexing in the Thunderbird settings and Thunderbird is now responsive and back to normal.

Is anyone else seeing anything like this? Any suggestions to fix the problem?

I am a long time Thunderbird user so my profile is very large with a lot of accounts, and has been through a lot of Thunderbird versions, so it is potentially more complicated than normal.

Thunderbird version is currently 128.1.0esr (32-bit).

Thanks

I'm experiencing an issue with Thunderbird that started unexpectedly. Whenever I try to access my email, I get a warning message saying that "The site certificate is not valid for this server. Someone may be trying to impersonate the server. It is not recommended to proceed."

I'm not sure why this error has suddenly appeared, as everything was working fine before. I haven’t made any changes to my email settings or installed new software recently. Has anyone else encountered this issue or knows how to resolve it?

Although I have my email trash folder set up to keep trash emails until I decide to manually remove them, many or most of them disappear as soon as I click on the trash folder. How do I fix that so trash emails aren't automatically deleted?

This is kind of a long story, I will keep it as short as I can without compromising details. All of the suggestions on the support page have not helped in any resolution. So, yes, I have been reading it for days now.

Originally I was getting the error message "The certificate for mail.*.com is not valid for that server. Someone could be trying to impersonate the server and you should not..." I tried to make everything right on the settings for both smpt and the imap server settings. Nothing fixed it. Eventually I elected to uninstall TB and rename the folder under users/user/appdata/roaming/...etc. Basically start fresh. This is my boss's TB and he has had all sorts of issues since switching from POP3 to imap. It was working fine for a few days, then he got that original message about the possible impersonating server. Anyways, so I started fresh and got it all re-setup and it was working again. Inbound came in and sent went out no problem. Then TB updated to the more recent version 128 and then a new error occurred. First, " Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent." So I chose not to save because it was just a test email. Then I doubled checked everything (nothing looked wrong) and I tried a new test email immediately after and another new error came up. "Sending of the message failed. Unable to communicate securely with peer: requested domain name does not match the server's certificate. The configuration related to must be corrected." I have tried getting and exception but it says that I don't need one. The certificate seems fine, though I only know enough about the certificates to be dangerous.

One more problem is I cannot get all of the old local folders onto TB as they were before. I know where the file is, however, TB will not import it, nor can I just move the folder into the mail/local folders folder in the profile. I was hoping that would fix it, but it indeed did not. This problem I know is unrelated to the connection issues, but it is an issue needing resolved that I have not found a solution for on the TB help site yet.

Thank you in advance to whomever can help in these matters. B

Hello,

I've been using Thunderbird for quite a long time now. I manage two private mail accounts, one at t-online and one at GMX, with Thunderbird. Suddenly, since yesterday I cannot longer get access to my GMX account. When opening Thunderbird, I first get a popup requesting to enter my password for the GMX account (normally I needn't do that). When I enter the (correct!!) password, it is not accepted, and I get an error notification (see attached screenshot). "Try again" also does not help.

The t-online account I can operate in Thunderbird as usual.

What can I do to again get access to my GMX account via Thunderbird?

Thx and best regards Rainer

To try and rectify thunderbird not sending email to my outlook.com I have deleted the acount in thunderbird twice and reset it up each time. The problem is the IMPAP e-mail download works fine but sending e-mail either stays stuck on sending, times out or I get not authenticated on SMTP server. My send set up is :- Port 587 Server name: smtp.office365.com Connection Security: STARTTLS Authentication Method: OAuth2 User name: This is my outlook e-mail address ie name@outook.com I confirmed the message originating from Outlook asking to confirm access by Thunderbird. My Thunderbird is up to date with latest version. Any Ideas? Thanks! By the way, Thunderbird works fine with my GMail account for both IMAP and Sending mail - I deleted my gmail account in Thunderbird and re-istalled it - all reinstalled work fine but not so with sending e-mails to my outlook account.

Thanks Much.

As seen in the image, I have wasted spacing after the message in the list, how can I either remove the wasted space, or preferably, center the text as is the norm with outlook/emclient/others

It just looks and feels so unnatural and i just cant get used to it.

Hi, My wife and I have both been having trouble getting emails from Fasthosts. Have to click "get mail" many times, and eventually they download. No problem with Mailwasher or on Androids. Win 10. TB both 128.1.0esr

On 31 July, a day before the Thunderbird update from V115 to V128, the emails in my inbox no longer had reply or forward options and were addressed as coming from me as well as to me.

A yellow message at the bottom of each email read: "A unique identity matching the From address was not found. The message will be sent using the current From field and settings from identity Marcus Relton <my email address>"

My email provider thinks Thunderbird mistakenly believes these emails to be drafts. I have added on FolderFlags, which now has a V128 version since I first experienced this problem last week.

I am supposed to be able to right-click the inbox, go down the drop-down menu to properties then see another dialogue box but this isn't appearing.

I can only reply to or forward emails by right-clicking in the message in the inbox and I can't click on links in the email. I have to open the link then cut and paste them.

Mail.coop, here in the UK is trying to find a solution, having hoped FolderFlags would work, but if anyone has any suggestions, please share.

I saw someone had a similar problem with their drafts folder in April but the suggested fix didn't solve it.

Thanks,

Marcus
