I got an email from Microsoft saying my Live.com or Outlook.com email accounts won't be supported in Thunderbird UNLESS I change the settings to OAuth2 in incoming and outgoing server settings.

I even REMOVED the email account and re-added it making sure it was OAuth2.

But for my live.com & outlook.com email accounts I continually get prompts for passwords from Thunderbird. Sometimes I can't even click the RED X at the upper right to shut the prompt down. I just happens over and over until I give it what it wants.

I am tempted to shut down all Microsoft email accounts and switch to Gmail.

I have Thunderbird version 115.12.2 (64-bit) I used Windows 11 23H2 build 22631.3810 Windows Feature Experience Pack 1000.22700.1020.0

Any idea how to stop these prompts?

I like Thunderbird much more than any other email program I have ever used, and would like to keep it

The inbox had about 18 months worth of emails. I deleted three emails that had been flagged by Thunderbird as spam. Then I went to the trash folder and permanently deleted the trash that included many other unwanted emails.

When I returned to the inbox, the full list of emails was present but after clicking on any email there was no email content shown. A new email came in and the content was shown for that email.

The sent folder still shows all the sent emails.

After looking for solutions on the web, I selected the inbox, right clicked and opened properties. I then selected "Repair Folder". Now, the only email shown in the list is the new email that came in after the issues started.

I have looked for crash reports and it says there are no crash reports.

Suggestions....? Thank you, Peter

From the article "Microsoft OAuth Authentication and Thunderbird in 2024" there is a screenshot showing a OAuth2 option for the SMTP server setting with STARTTLS connection security. It does not appear for me. There are only the five options, as shown in the screenshot. How do enable the option to be available in the drop-down list or set it?

The available options are:

No Authentication Normal Password Encrypted Password Kerberos / GSSAPI NTLM

I am on Thunderbird version 115.12.1 (64-bit), Windows 11, version 23H2, build 22631.3737

I have been marking as Junk on some messages for years now. When does TB ever send those directly to the Junk file? Specifically. Can I create filters to send any message I mark junk to the junk file under Local Folders? I've tried and can't seem to get junk messages sent direct to that Local Folder Junk file. Is there some trick to how you create a filter? The way I've been doing it is: Open Message Filters, check "Filters for: and click the email address. Then click New for a filter. Then, in the new filter, type in Filter name:. "JUNK". Leave ck mark in Manually Run, Getting New Mail as "Filter before Junk Classification" (Or should I use Filter after?). Leave ck mark in "Match all of the following. Now, Subject, contains - and that's where the email address goes. Usually I have copied it from the junk message and paste in. And finally, Move Message to: Junk on Local Folders. So why don't this work? And as far as I'm concerned Spam should be the same. Do I need to create filters for both junk and spam? And both before junk classification and after?

In doing some file and folder cleanup I just ran across a folder that I don't recall seeing previously. It is on my local drive and labeled EES-temp. It contains 27 files from the last month and a half and one from 2017. Most but not all of them appear to be items I have filed in other folders. Can someone tell me about this folder? Can I delete it? It looks like it was created by TBird.

The problem is that after the download of the 115.01 version it has not been possible to register properly my "name"@arcor.de account with the email provider via imap.vodafonemail.de from Thunderbird . With imap.web.de there has been no problem. Strangely, it is possible to send emails via smtp.vodafonemail.de from Thunderbird although these sent emails are not shown neither in Thunderbird nor in the Vodafone email app. Incoming emails are properly shown in the Vodafone email app but not in Thunderbird.

Thunderbird just updated to V115. But now, I no longer can see anything. Nor, can I navigate to anything since there is nothing there? How do I either fix this, or revert back to an earlier version that worked? See attached screenshot.

I use thunderbird for my email - have been using thunderbird for years and love it. :)

Below is the message I get, I only this error when using thunderbird, not when sending messages from the outlook 365 account with the same email.

This make me think this is not a outlook server error??? how do i fix this.

Thank you in advance.

Hi,

My reading pane on v115 will only adjust downwards but I would like to adjust it upwards as was possible in previous versions.

Just to confirm what I mean, it will only go down, so making the reading pane smaller (or disapppear) and the thread pane larger.

I would like to make it go the opposite way, upwards to make the thread pane smaller.

Is there some code, css etc that can make it happen correctly?

It was barely noticable, but SERVER NAME in Server Settings was the same for both accounts. These were Yahoo IMAP accounts. Each account had its own folder in Users / ....... / ImapMail, but both accounts were pointing to one folder. Corrected this in the SERVER NAME field in Server Settings (see image)

"SHOULD" solve the issue .......... particulary it is THE ONLY item I can find that was not normal.

After upgade Thunderbird to 115.0.1 version, all my outlook.com email accounts encounter an error:

Warning: Potential Security Risk Ahead Thunderbird detected a potential security threat and did not continue to account.live.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What is the problem? Doesn't TB support outlook.com accounts anymore?

thanks.

I have used Thunderbird for 12+ years. Now that we have AT&T as our new ISP, I have learned that AT&T doesn't provide an email address. I had no idea and I am frustrated. I also have Gmail, but I am not happy about trying to merge my large Gmail file with my 17 GB Thunderbird file. I worry about losing emails from years ago saved in Thunderbird and in Eudora before that! I assumed I would get an AT&T email and go on as before. Now what?

I suppose it wouldn't be the end of the world to use Gmail all the time. I hate its filing system which is why I want to keep using Thunderbird. I worry as both files are large. Can I really merge all this stuff and not lose my old emails?

I have TB 102.13.0 (64-bit) with a bespoke location for the profile (in my Dropbox folder). All the mail collection, storage, folders are working perfectly well but when I change the descriptions for tags and my email server settings (user name and password) - they don't stick. For the password, TB says I have to restart, which I do and afterwards it has reverted to the same settings.

I have changed permission for the Profile folder so that ALL USERS plus my login user has total access and it is not Read Only, and I have also found the folder in Roaming for Thunderbird and changed those permissions.

Is TB saving these settings somewhere else that I don't know about?

Please help, it is making my work difficult as I use the Tags for different clients and stages of work.

Thanks User in UK

I receive incoming email on Thunderbird, but cannot send mail. I have used Thunderbird for years, never updated it and this problem just started yesterday (7/25/23). I have gotten an error message saying "login to server smtp.nycap.rr.com failed". I have called my ISP, Spectrum, and ascertained that my email account with them is functioning, so the issue is something with Thunderbird.

Thunderbird is completely unusable in the latest release. Attempting to set up a gmail based account results in

"Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to 192.168.1.250. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

That's it. No options, no explanation, no KB articles, nothing. It just doesn't work. But why is Thunderbird trying to open a web connection to my local machine? If it's trying to talk to itself, why can't it? This is clearly an issue with trying to authenticate to Google as it happens after auth, but come on, this is a given requirement these days. If your app doesn't work out of the box (MacOS 13 btw), it may as well not exist for the OS, so this is very confusing.

Trying out older versions was a real comedy of failures as well. Too old and it's just a disaster. Too new and it just self updated to 115 again which doesn't work. So kinda seems like this is not a functional app anymore, at least not on Mac. Baffling. I guess it can only be used with legacy style email systems.

I have been getting messages to up date Thunderbird. The first 3 were last week, and appeared to be in Chinese. Today I started to keep the update messages in English. So I went the the thunderbird update release channel and downloaded the latest release. But, I am still getting notifications to update thunderbird. I rechecked the release channel and am using the current version.

So anybody know what is going on?

Hi there, I use iPrimus. I can Receive emails. I am currently based in Thailand (previously Australia - no issues)

Whenever I attempt to send an email from Thailand, I get the message: "Send Message Error Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: smtp692.syd.oss-core.net."

Outgoing Server Settings: smtp.iprimus.com.au Port 587 (default) - (NB I tried 465 without success) Connection: STARTTLS Authentication: Normal Password

Hi

I have endured weeks of Thunderbird conflicting with Hotmail.

Occassionally it works.

Today is another 'no go' day cannot trans or recieve. Hotmail online works but not Thunderbird.

What is going on at Mozilla ?

For the last week I have been unable to send emails from my main email account (Bigpond) because an error/alert message pops up (see attached). I have check the Outbound Server settings and they are correct. I have also successfully sent emails from my providers Webmail as well as from my Gmail account in Thunderbird without an issue. Any assistance would be appreciated. Thanks Peter
