My wife & I have the same PCs running Windows 10 & Thunderbird 115.11.0 (32bit).

We have a hosted web-site that also supports email, and we each have an email account (eg neddy@goon.com.au & minnie@goon.com.au). I've checked that both our POP server configurations are identical but despite that about once a week minnie@goon.com.au receives a warning to add security exception but neddy doesn't. This started happening two weeks ago after a years error free running.

The host has checked that goon.com.au has a valid SSL certificate, so what could be causing the discrepancy and how do I set about fixing it please?

I have Thunderbird 115.8.0 installed on my MacBook Pro with two email accounts, Yahoo and Gmail. I have set up the Tools/Message Filters/Block Filters as well. When I first launch Thunderbird all the spam shows up in my inbox, and just sits there. What I have to do is go to Tools/Message Filters at which point I'm asked to select an account. I select Yahoo (my primary account) and then "Run Filters" before anything actually happens. Then if I go back to my inbox, the spam emails start disappearing. It seems that Thunderbird does not remember the "Yahoo" selection in filters in between launches. Is there a setting I am missing, or is this just the product of having two different email accounts? Thank you.

TB 102.5.0 (64-bit) on Win10 I'm getting repeated notices that my e-mail accounts with Network Solutions don't have a proper "certificate" when I try to send an email. I get a popup window stating so, and asking me to "permanently" choose the exception. It doesn't matter how many times I tell the fool thing to accept the exception "permanently". I still keep getting the notice every few times. Since the glitch is not consistent, I don't have an image of one to put here. Not only that, I have to send the email twice after doing so. TB refuses to send the email the first time after choosing the exception, but allows it the second. I don't know anything about "certificates" and am sick of getting popup notices about them. I doubt that the problem is with Network Solutions email accounts. This reminds me of years ago, when I tried to upgrade to WinXP. It kept interrupting my work to give me popup security notices that I didn't understand and couldn't do anything about. If I remember correctly, I took it back to Sam's Club and replaced it with Win2000. Problem solved. Never mind that XP was supposed to be better. If it ain't broke, don't fix it.

Hello,

I am using the latest stable release of Thunderbird client on Windows 11 and just today it's been asking me multiple times for a password to my Outlook account. I have kept adding a one time app password through the official Microsoft website under account management but it's been asking a few times that it needs a password.

Do you know if there's been any outages to the Microsoft servers or what this issue could be related to? Is there a way I can send any logs directly to you that might help find the issue?

Thank you for your time.

Microsoft tell me that I must use OAuth2 for my accounts, else I'll be locked out.

Server is imap-mail.outlook.com. If I select OAuth2, then I can't receive emails unless I reset back to Normal Password.

I'm also supposed to set my SMTP server (smtp-mail.outlook.com) to OAuth2, but this isn't an option on the drop down list.

Help, please!

I recently installed Thunderbird on a Windows 10 desktop and setup a brand new profile from scratch with multiple email accounts.

It worked fine for 24hrs, with all passwords saved. Following an install of some other software (CorelDraw and Adobe Suite) the computer was rebooted. On starting Thunderbird it asked for all the account passwords again. Having entered them all, and ticked the box for password manager to remember them, none of them were saved.

I tried deleting parent.lock (which I didn't think should be present once the program has been shut down), key4.db, cert9.db and pkcs.11.txt from the profile and restarted Thunderbird. It requested all of the passwords again and again none were saved.

If anyone has any further ideas as to what could be causing the problem I would be grateful.

I have received an email from Microsoft informing me of changes to its authentification procedure. As from Sept, to continue using Thunderbird to access my outlook/hotmail accounts, I have to change the authentification method to Oauth2. The reasons and changes required are detailed here: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 I have 2 problems. 1. imap-mail.outlook.com - I can change my authentification method to Oauth2. However, when I then try to access my mail via TB, I get an error stating that the server imap-mail.outlook.com does not support the authentification method! (see image) 2. Outgoing Server SMTP There is no Oauth2 option available to choose!

Can anyone help? I am using the most up to date version of Thunderbird 115.12.2 (64-bit).

Suddenly today my Thunderbird email account on my desktop won't send or receive mails until I enter the password. When I add in the correct password it doesn't accept it but just comes back asking for it again. I suspect it is best to change my password but don't know how to do that. Incidentally the account is working fine on my phone and tablet with the same password but not on my desktop. Can anyone help? Thanks.

My Thunderbird Version: 115.12.2 (32 Bit)

Microsoft is changing the authentication method for outlook mail to OAuth2. I follow the guide here,

https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

And I get to this screen - but my version of the program does not have OAuth2 as an option (see attached image).

Thanks for the help.

Thunderbird continues to block my outgoing emails despite my best efforts. Please check my outgoing smpt server settings (attached) and let me know what I need to change. Thanks.

From Sept-16-2024 Microsoft will deprecate Normal Password and require OAuth2 authentication on its email accounts accessed from Thunderbird and other clients.

I'm trying to convert my hotmail accounts on Thunderbird to OAuth2 authentication.

Server Settings Authentication can be set to OAuth2 because OAuth2 is an option in that menu.

But SMTP Server Authentication cannot be set to OAuth2 because OAuth2 is not an option in that menu.

Both Connection Security methods ( Inbound and SMTP ), are set to STARTTLS.

See screenshots, thank you.

Hi,

I have a fire2wire.com account. I use Thunderbird for all of my email correspondence. About six months ago, I started having to put my password in every time I open Thunderbird, and again when I try to send out an email. Can you tell me how to remove the password requirement?

Don djordan@fire2wire.com

After changing passwords at the email provider, it asked for and saved the passwords for the incoming server. It asked for the SMTP password for the first account and saved that (using that username) but did not ask for or save passwords for the other accounts using the same SMTP server.

So... email can be received on three accounts but can be only sent from one. Is there some way to add the passwords?

I am having issues with Thunderbird not retaining my email server and passwords. Each time I want to send an email, it prompts me for the password and then tells me that the email address and server don't match. I have tried numerous times to correct this, but it doesn't hold the information. It also switches the server info between accounts. I have 3 different email account and sometimes only one works correctly

I updated my comcast password recently. Now when I try to send an email I get error about password - dialog comes up one option being reset password. When I click this I expect a dialog to open allowing me to enter the correct password but nothing happens.

I went to saved password dialog and removed the entries there hoping that would force Thunderbird to ask me for password - no joy.

In the Beta version how do I update SMTP password? I do not want to recreate the profile because then I lose lots of stuff - I JUST want to update the SMTP password. None of the pages I find are helping me.

Microsoft sent email last night announcing the end of "Normal Password" for Hotmail, and warning that Hotmail would REQUIRE "modern authrentication" beginning 9/16. I have personal desktop subscription to Microsoft 365. I have set Microsoft account to 2FA and checked in Tbird that cookies are enabled.

I have spent hours and days trying & failing. With server imap-mail.outlook.com using OAUTH2, Thunderbird won't sync and shows message saying that server doesn't support the authentication protocol please enter another one. With 2FA still turned on and using Normal Password setting and entering an App Password from Microsoft, the Imap connection is fine about 85% of the time, needing re-entry of the App password about once a day or so (usually requires several tries until App Password gets accepted.)

The 0AUTH2 fails with Norton Smart Firewall turned Off or Turned On-makes no difference.

(Sending email with Outlook and 0AUTH2 DOES work okay.)

I've also tried Imap connection with a different server: Outlook.office365.com, using 0AUTH2.

In this case, Tbird shows me a Timeout error and never makes an Imap connection to the server.  

I've been limping along with the app password, and "normal password" authentication, but now Microsoft announces they will stop accepting connections that are not 0Auth2 ("modern authentication") from Tbird or any other software after 9/16. The clock is ticking. I've tried every remedy I've seen online from Tbird or from Microsoft. Nothing has yet allowed a QAUTH connection for Tbird to a hotmail IMAP server. Please help! !

i want to disable my spamblocker/ junk mail detector in firefox ..... it keeps sending legit emails to the spam file no matter how i adjust the junkmail settings....is there a way to just turn the spam/junk detector off altogether?

i already have spam detector through my cPanel at my webhost and another junkmail detector in antivirus/malware program on my desktop

i don't need firefox diverting legit emails that get through the earlier detectors.

I changed the password of one of my emails when trying to configure it for my phone. I forgot that it was set to 0auth2. So now I have changed the password and can open the Gmail, account online OK, but I can't find how to go back to the 0auth2 password. 0auth2 is still set in Thunderbird but I have no idea what the old 0auth2 code was. How can I update it to work again?

Hello,

I have been using Thunderbird for years to collect all emails in one place with out issue. In the last few days authentication has started failing. It started on one gmail account prompting for a password. When I enter the password it is rejected. A second GMail account is now doing the same and one of my Yahoo accounts is now doing it too.

I can still access the accounts on my phone using Oauth2.

Nothing I have tried fixes it. I am in danger of losing access to all my of my email accounts on windows.

What is going wrong?
