Hello,

I am requesting assistance with a persistent issue in Thunderbird involving a Google Workspace (Gmail) account for my domain, dantanas.com.

Incoming IMAP works correctly. However, outgoing SMTP authentication fails every time.

Symptoms

The Google OAuth login window never appears when Thunderbird attempts to authenticate SMTP.

Sending mail produces the error: “Unable to authenticate to Outgoing server (SMTP). Please check the password and verify the authentication method.”

IMAP works normally, but SMTP never prompts for OAuth authentication.

Thunderbird also does not allow me to have a Junk/Spam folder for this account — the option appears disabled or unavailable.

Current configuration Thunderbird is using

SMTP Server: smtp.gmail.com Port: 465 or 587 Security: SSL/TLS or STARTTLS Authentication: OAuth2 User: max@dantanas.com

IMAP Server: imap.gmail.com Port: 993 Security: SSL/TLS Authentication: OAuth2

What I have already done

Verified DNS MX and DKIM records on the domain (email receiving works).

Confirmed I can log in to the account in a browser with no issues.

Tried both port 465 and 587.

Removed and re-added SMTP servers in Thunderbird.

Forced Thunderbird to attempt OAuth2 authentication, but the OAuth window never appears.

Tested other clients, which authenticate correctly — suggesting the issue is specific to Thunderbird.

Expected behavior

Thunderbird should open a Google OAuth browser window to authenticate SMTP. This never occurs, which prevents SMTP from working entirely.

Request

Could you please advise:

Why Thunderbird does not open the Google OAuth authentication window for SMTP?

Whether there is a known issue affecting Google Workspace OAuth in Thunderbird?

How to reset or repair Thunderbird’s OAuth behavior?

Why Thunderbird does not allow the creation or use of a Junk/Spam folder for this account?

Any guidance would be appreciated. I’ve spent considerable time troubleshooting, and resolving the OAuth prompt issue is essential for SMTP functionality.

Thank you, Max Makowski max@dantanas.com

Hey Forum, 2 problems.

1. 1. - I have been having some problems w/my paypal account. Someone has been trying to hack into it. Twice in two weeks. I talked to a paypal tech and was told that they are accessing my emails. And she advised changing my email password. I have use Tbird for several years and don't remember having a password. But if I do, where is it, and how do I change it?
2. 2 - For awhile now I have been getting an error message when trying to send an email. (I can recieve, but not send). it says: "Enter your password for ***********@suddenlink.net on smtpsuddenlink.net" Where would I find such a password and where is smtpsuddenlink.net? Also could the above problem be related to this one? They started about the same time.

Hi everyone, I’m facing a very strange issue when trying to authenticate a Hotmail account via Microsoft OAuth2 in Thunderbird (and also in Firefox).

When the Microsoft login popup appears, I **cannot focus the password field or the verification code field**. The focus just cycles through other UI elements (buttons, dots at the bottom right, etc.), but **never stays inside the input field**, so I can’t type anything. Clicking into the field does not help — the focus immediately jumps away again.

This only happens in:

• Thunderbird 128.12.0 ESR (32-bit) on Windows 10
• Firefox (same behavior)

But Edge and Chrome work normally.

What I already tried (no success):

- Removing OAuth tokens and clearing authentication files in Thunderbird - Disabling Enhanced Tracking Protection in Firefox - Disabling browser extensions (ad-blockers, NoScript, Privacy tools) - Checking and modifying Firefox `about:config` privacy settings - Clearing and re-authorizing the app under Microsoft Account permissions - Restarting in Firefox Troubleshooting Mode - Switching temporarily between OAuth2 and Normal Password authentication - Testing on fresh login windows after restarting Thunderbird - Maximizing the popup, using tab/keyboard navigation tricks - Turning off Windows Security controlled folder access - Testing with different networks

None of the above solved the issue.

Additional notes / clues:

• Problem affects only **Thunderbird + Firefox**, not Chromium browsers
• Windows 10 system
• Thunderbird is running **32-bit ESR**, so it uses Gecko/Firefox ESR 115 engine
• This looks like a **focus bug in the Microsoft OAuth WebView implementation** on Gecko-based apps
• I can't complete the OAuth login, so I’m stuck without access to the account

What I’m asking the community:

• Is this a **known ESR bug** with Microsoft OAuth?
• Is there a workaround or patch for Gecko WebView secure input fields?
• Any configuration that I may have missed?

Any help or guidance would be greatly appreciated. Thanks in advance!
