I have created several gmail addresses

But there is 1 address that is impossible to add to Thunderbird.


I always get the same error message.

the address and password are correct. I checked on my browser with the gmail box.


I've deleted, manually changed the password in Thunderbird but nothing. the synchro is impossible.


However, the other emails work perfectly.

Chosen solution

I uninstalled and cleaned everything!

I loaded a previous backup.

All new addresses are correctly loaded in thunderbird.

The Authentication Method says 'SSL/TLS' Gmail uses 'Authentication Method' : 'OAuth2'

I'm surprised it did not select Oauth automatically, but manually alter it to Oauth2

Also the email address is not displaying (maybe you edited it for obvious reasons?) you need to enter the username = full gmail email address.
