I didn't change anything in my settings, but as of yesterday I can't send any more emails with my gmail account. My work address is still working, maybe since it is a Google Apps account.

Here are my settings for the account that doesn't send (note it is the same for the account that does work): Server: smtp.gmail.com (previously it was working with smtp.googlemail.com but now neither works) Port: 465 Security: SSL/TLS Authentication: was "normal password" and that that was working until yesterday, but one Google forum suggested I change to OAuth2 (which doesn't work either) Username: My-full-address@gmail.com

With those settings, now when I click send it asks for my gmail username and PW, then brings up a window that says "If you’re trying to use your Google Account and see a message saying your browser's cookie functionality is turned off, it’s likely your browser's cookies are disabled. You’ll need to turn cookies on to use your Google Account." I also got the error "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again."

So is Thunderbird wanting to look at my Cookies in Chrome? I do have Cookies enabled in Chrome, so it shouldn't be a problem, but just in case I cleared the cashe, and no luck and I even disabled then reenabled Cookies again.

Chosen solution

Ok, I found the solution: In my Outgoing Server SMTP Settings, I was previously using SSL/TLS with "Normal Password". Since I couldn't get that account to send I deleted that SMTP server setting, and just added a new SMTP Server (with the same account information). This time I set it to SSL/TLS with "Encrypted Password" and now it works... Emails send and receive just fine now.

But I don't understand why some of my other email addresses that access the same server smtp.gmail.com still work with "Normal Password". In any case, I think I'll start using 2-step verification for my Google account.

Likely you need to set up a Google App password for Thunderbird to use. Don't bother asking why Google suddenly wants you do this. They basically want everyone to do this sooner or later.
