Setting up Gmail with Thunderbird V 78.12.0

more options

Have an existing Gmail account that was working great for years with TB, now each time I try to open TB I get the error:

Login to account ".......@gmail.com failed with three boxes with these options:

Retry Enter New Password Cancel

Retry gives same error as above

Enter New passsword for .........@gmail.com is entered then OK (the correct password is there already) then same error as above!!!

In the email server settings for setting up Gmail to work with TB the instructions say:

Use the table below to update your client with the correct information. For help updating your settings, search your email client's Help Center for instructions on setting up IMAP.

Incoming Mail (IMAP) Server

imap.gmail.com

Requires SSL: Yes

Port: 993

Outgoing Mail (SMTP) Server

smtp.gmail.com

Requires SSL: Yes

Requires TLS: Yes (if available)

Requires Authentication: Yes

Port for SSL: 465

Port for TLS/STARTTLS: 587 Full Name or Display Name Your name Account Name, User name, or Email address Your full email address Password Your Gmail password


HOWEVER in the actual setup there the options for Security Settings are different than the instructions above:

For Incoming Server

Connection Security:

None STARTLS SSL/TLS

and for Authentication Method:

Normal Password Encrypted password Kerberos/GSSAPI NTLM TLS Certificate OAuth2

and the same options apply to SMTP outgoing Server setup screens

my port number settings are correct my emailname is correct the password is correct the account is setup as IMAP the server name is imap.gmail.com and the outgoing server name is smtp.gmail.com

my security settings both incoming and outgoing servers are:

for connection security: SSL/TLS for authentication Normal password

There is NO option to choose "requires authentication:yes" as in the instructions to setup


but unable to send or receive gmail thru thunderbird

Please help what option under security and authentication works? for both incoming and outgoing servers?

Thank you

Use imap.gmail.com on 993, SSL/TLS, smtp.gmail.com on 465, SSL/TLS, or 587, STARTTLS; authentication = OAuth2, User Name = email address. Accept cookies in TB Options/Privacy & Security. Remove passwords from Saved Passwords in Options/Privacy & Security, restart TB, enter the confirmed working password in the OAuth window when prompted.

Thank you the one that fixed this is changing "Authentication method" under "Security settings" for both incoming and outgoing server is to use:

OAuth2 with SSL/TLS for imap.gmail.com on port 993

and

OAuth2 with SSL/TLS for smtp.gmail.com on port 465

that solved the problem and now can receive and send Gmail through Thunderbird

Thanks again for the quick solution
