Thunderbird Support Forum

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?

Best Regards, Margaret Mackisack

I hope someone can help, I've changed all the settings in Thunderbird for my whole family's emails (hotmail.co.uk, hotmail.com, live.co.uk) from Normal Password to OAuth2. All incoming and outgoing servers are exactly the same as Microsoft advised. None of my accounts work, neither for sending or receiving.

I removed one account and tried to re-add it (that was the advice given if the first method didn't work) but when it tries to check the password, it takes forever. I've tried to manually configure it but it wouldn't download any folders or emails. I removed it and tried to re-add it but have been unable to do even that.

My default account hasn't been able to send more than 25% of emails for a few weeks. I'm up to date with all updates and I've restarted Thunderbird and my laptop countless times.

Can anyone point me in the right direction please?

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! !

Microsoft is changing the authentication method for outlook mail to OAuth2. I follow the guide provided to update Thunderbird, but my version of the program does not have OAuth2 as an option. My outgoing server is smtp-mail.outlook.com, but OAuth2 is not an option in the dropdown for authentication method.

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).

Issue began Monday 7/1 where Thunderbird would not receive new email from AOL. At times it would tell me to enter the password. But the p/w I entered was not correct so that made situation worse. Found "Saved Passwords" in Help->Settings where I was able to retrieve the -correct- p/w for one of the email addresses being actively used in Thunderbird and problem solved. When I went to find the correct p/w for the other email address, the account in "Saved Logins" was not there?? Was odd that the list did display email accounts I haven't used in years, but not the 2nd one that I use daily! I tried changing the p/w at AOL Mail, but that didn't work for either of my two accounts. Bottom line, why isn't lf82me@verizon.net showing up in the "Saved Passwords" in Settings?

I use Thunderbird 115.12.2 (64-bit) with Hotmail, using a local account on Windows 10. Microsoft is introducing 'modern authentication' on Hotmail, and I want to be ready for this, but I cannot follow the guidance at https://support.microsoft.com/en-gb/office/modern-authentication-methods-now-needed-to-continue-syncing-outlook-email-in-non-microsoft-email-apps-c5d65390-9676-4763-b41f-d7986499a90d

If I try to alter my existing Thunderbird Account Settings for my Hotmail account, the authentication method for Outgoing Server (SMTP) is shown as Normal Password but there is no option to change it to OAuth2. If I delete and recreate my Hotmail account in Thunderbird, I get an error message from Microsoft saying that I cannot log in because my browser is not set to allow cookies -- even though I believe I have set both Thunderbird and Firefox (my default browser) to allow cookies.

Tell me how I can continue to use thunderbird with the above account and also Denis.Clarke.hotmail.com after September 18. I have 4 individual historic E mail accounts and thunderbird joins them together. What do you need to do? To deal with threat below.

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Hi, I've just had an email from Microsoft saying :-

Update your sign-in technology before September 16th, 2024 to maintain email access.

Is there a step by step tutorial on how to do this?

Regards,

Paul

Having followed the instructions at https://support.microsoft.com/en-gb/office/modern-authentication-methods-now-needed-to-continue-syncing-outlook-email-in-non-microsoft-email-apps-c5d65390-9676-4763-b41f-d7986499a90d to update the security settings on my outlook/hotmail email accounts Thunderbird no longer reliably saves/enters the passwords. The password is saved in settings as that is where I copy it from to enter manually but why is Thunderbird not doing the entry as previously. It is not every log in and not always the same account, but regularly one or the other will come up with "enter your credentials" Also occasionally the credentials screen will flash on screen and then disappear, not necessarily for the account I am using at the time but one of the others. Any help appreciated Thanks Paul

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.

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

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.

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.

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.

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?
