Toad-Hall, Christ1, Matt thank all of you, I FINALLY solved the mystery. extremely frustrated (I have been forced to us ms mail which i really don't like, i am too used to thunderbird (although I wished thunderbird had check boxes on emails to select via checkboxes for delete, or moving, etc)

I have to hit cancel it then shows Failed message unable to authenticate.Īfter I deleted the 3rd party app password in gmail settings, now when i start thunderbird or try to receive emails, it goes through the same authorization process with my phone, but, then never downloads any new emails. with the progress marked all way to end BUT, it will never complete sending. I did this just for smpt first when the 3rd party app password was still enabled, i could recv but, when i went to send, it would ask for password, i enter it, then it would sent msg to my cell phone to Allow thunderbird, i would press Allow on my phone, and Thunderbird would come up with Sending message. Then I read to use OAuth2 and saw that Google will no longer allow 3rd party app passwords, so i deleted it in google, and set both and to use OAuth2 (both set for SSL/TSL).

That allowed me to Send Gmails, but, not receive it kept asking for password. I used to send/rcv gmail no problm, started having issues ~ Oct 2021 I then setup a 3rd party app password in gmail account for thunderbird.
