Unable to Add a Gmail Account to Thunderbird Despite Successful Authentication
Hello,
I’m having trouble adding my Gmail account to Mozilla Thunderbird. The Google authentication process completes successfully, but the problem persists in Thunderbird, and I’m unable to configure the account correctly.
I have double-checked the account names and credentials, and I can confirm that they are correct. The authentication process has been completed successfully multiple times, and the passwords have also been verified. Therefore, the issue is not caused by incorrect account names, passwords, or authentication details.
I have attached screenshots showing the problem for reference.
Could you please help me identify the root cause of this issue and explain how to resolve it?
Thank you for your help.
Best regards,
