Thunderbird Support Forum

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).

Changed Gmail.com password and now Thunderbird will not login even with the new verified password. I have tried all recommendations on the internet and nothing works.

Hallo, durch eine Unachtsamkeit habe ich das Hauptpasswort (Primäres Passwort.) von Thunderbird gelöscht. Ich finde auf den Hilfeseiten keinen Hinweis wie man da Passwort zurücksetzten kann. Dadurch komme ich nicht mehr an meine Mails. Freundliche Grüße

WHY is it that I can get into my email account through Thunderbird and download mail, but when I try to go into the account manually I can't? I go into the settings copy the password, then manually input it into gmail, but it says it's the wrong password? I am using MacOS 10.14.6, and Thunderbird 115.12.2 (64-bit)

Thanks.

I have TB ver 115.12.2 64 bit. It reports as being up to date. During attempting to make the changes necessary to accommodate Microsoft's Modern Authentication I reach a point where the option to select OAuth2 does not appear in the Outgoing Server SMPT settings drop down menu, see the image. How do I deal with this? Thanks for your help.

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! !

Dear Sir or Madam,

I have just migrated Thunderbird to my new CUBI desktop running Windows 11. I get security errors when I launch Thunderbird. My email provider The Messaging Company advised me to change server settings, which are now shown in the Troubleshooting Information page as account1 (pop3) pop.themessagingco.com.au:995 SSL/TLS Normal password smtp.themessagingco.com.au:587 STARTTLS Normal password true.

On launching Thunderbird I get the message Secure connection failed live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

   This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
   If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception…

AND when I attempt to send an email I get warning that the SMTP server does not have a valid certificate. If I ask, in either case, to "Get Certificate" the response is that the site attempts to identify itself with invalid information.

I have "tried again later" over two weeks, and nothing has changed.

The Messaging Company is a fairly large email provider: it seems strange that its security is incomplete. However, I am not happy to just set an exception and over-ride these errors without doing all I can to check that there is not something screwy going on. I really value using Thunderbird, and The Messaging Company's advice that I should just use webmail is not at all satisfactory: I keep everything on my computer or backed up to a portable drive here.

Please: is there anything I can do or should know to fix this problem?

Hello,

When the primary password window opens and I click Cancel, can that window close AND can it prevent Thunderbird from opening?

Example: what if I bring my pc to a repair shop and they open thunderbird and click Cancel on the primary password window. They can See my previously viewed email. I do not want them to see those. Clicking Cancel AND closing Thunderbird would prevent them from seeing emails.

Could this be a future enhancement?

Thanks

Jim

I would like to change my account settings for my hotmail account, but when I try to change from Normal Password under Outgoing Server (SMTP) there is no option for Oauth. Is there something I can do to enable this option.

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.

I am running version 115.12.2 (64-bit). I have deleted all stored passwords using Settings -> Privacy and Security -> Show Passwords. As expected, when I try to retrieve emails a pop-up appears asking for the password - which I save. However, when I try to send an email there is no pop-up and the remote server rejects the email. How do I set a new outgoing password?

Hello,

So - SMTP suddenly stopped working in our whole company. We are using Gmail accounts configured with Thunderbird for a few years already. It's all been working until an hour ago.

Tried deleting and adding accounts, changing authentification to google app passwords etc.\

SMTP servers do have different descriptions.

Just configured an account in outlook and it works out of the box, so I'm guessing it's got something to do with Thunderbird settings, but we didn't change anything, and especially that we have 8 PCs and it stopped working on every one of it.

The error I get when trying to send a message is:

"Sending message failed. The message failed to send because it failed to connect to the outgoing mail (SMTP) server "smtp.gmail.com". The server may be unreachable or not accepting SMTP connections. Please verify that your outgoing mail server settings are correct and then try again or contact your server administrator."

(translated from polish).

Best regards.

Without notice, Thunderbird today required me to sign-in to my Google account and then produced a window in which it said it wanted to access to my mail, contacts and calendar; in order to compose, send, share, delete permanently, among actions on my personal content. I tried to "Deny" (see below) but the window just returned and returned and could not be deleted. (see "Uploaded images", below for the content of this window).

Is this a scam? Or the result of a hacker?

Lately I have been getting a lot of spam and have identified all coming into my inbox as spam. Now many are automatically moved to junk mail box and that is a good thing. Unfortunately it also seems to be slowing Thunderbird down. I am afraid that many of the "Filters" generated may be duplicated. Is it possible to see them and maybe edit them to reduce the impact on my system?

I've used Thunderbird for years using a POP setting; Network Solutions would prefer that I use IMAP. I don't know the difference, but they must and prefer that it be IMAP (netsol-imap-oxcs.hostingplatform.com) (PORT: 993. When bringing up the settings in my mail account, it doesn't allow anyone to change that field. What can I do? I want to use Thunderbird; because of this particular setting I haven't been able to, and must instead log on to Network Solutions and go through their email interface. Thank you.

I've appreciated using Thunderbird for an ad-free Hotmail experience for quite some time. I've changed my Hotmail password every few weeks lately and Thunderbird worked fine when I entered the new password at the prompt when Thunderbird started.

Just now however, I needed to get into my Microsoft account that uses the same password as my Hotmail account. My login to Microsoft failed. Trying to understand why, I looked in Thunderbird at the saved password for Hotmail's server:

oauth://login.microsoftonline.com (https://outlook.office.com/IMAP.AccessAsUser.All

https://outlook.office.com/POP.AccessAsUser.All 
https://outlook.office.com/SMTP.Send offline_access)

The saved password was a 464 character long ASCII string totally irrelevant to the password I'd selected for Hotmail and Microsoft.

I went through the password change process for Hotmail, was then able to get into my Microsoft account and restarted Thunderbird. As usual, Thunderbird asked for the new password. I entered it and was then able to receive new mail from the Hotmail server in Thunderbird. However, again, the saved password in Thunderbird for Hotmail was not the password I'd entered.

Next, I deleted the saved passwords in Thunderbird, restarted it and this time it prompted me to be sure I'd downloaded it from a reliable source. I've never seen that prompt before. It came with my Linux Mint installation, so I thought it would be safe, but again there's an irrelevant password saved for my Hotmail account.

It's like it eventually changes my password for Hotmail and Microsoft since I can get mail through Thunderbird with the odd password it saves, but if I use what should be my password for Hotmail or my Microsoft account via a web page interface, the password doesn't work.

I'll have to stop using Thunderbird if this continues.

Dear Sir/Madam,

I use the Thunderbird email client on my Microsoft Windows 10 desktop tower PC in order to access my Gmail account using POP3, using "only" my email address and password.

However, I note that Google plan to introduce more stringent and tighter sign in/authentication methods from September 2024 as follows:

https://support.google.com/a/answer/6260879?hl=en

https://support.google.com/a/answer/6260879?hl=en

Does Thunderbird have a workaround for Google's plans please?

Thanking you.
