Thunderbird not receiving emails since Google asked for permissions

Hi Graham,

If this is a Gmail account, it sounds like Thunderbird may need to authenticate with Google again after you granted the new permissions.

Could you try restarting Thunderbird and see whether a Google sign-in window appears? If it does, sign in with your Gmail account and allow Thunderbird access to the account. Thunderbird uses Google's OAuth2 sign-in for Gmail, rather than simply using your normal Gmail password.

If no Google sign-in window appears, please let us know what happens when you click Get Messages. Does Thunderbird show an error message, or does it simply not download anything?

Also, if you can tell us which version of Thunderbird you're using, that would be helpful.

Hi Max!

I'm having about the same problem. 2-3 times per week, before or during receiving emails, TB sends some type of request to Gmail to verify my accounts. Google chrome pops us and askes me to confirm accounts (without asking for a password.) Additionally, I get emails and IM's from Google asking me to verify it's me trying to access the accounts. All 4. Never had this issue in 20+ years, yet within the last 6 weeks it's becoming a nuisance. I made sure all (4) Gmail accounts attached to TB are using Google's OAuth2 sign-in for Gmail Additionally, I removed all 4 Oauth2 within TB to let it reset in case there was an error there as well. I've tried Grok & Gemini to look for answers before I pestered you here. I'd certainly appreciate the help. Thank you! Devin
