I have had to change my gmail password on another account, so have also changed it in Thunderbird, but now I cannot send/receive emails in Thunderbird, although I can on my phone and tablet, which both now use the changed password. I changed my password in the Thunderbird “Saved Logins” page but it would not work, but the entry there originally was something totally different from my password, although unfortunately I did not note the wording before I replaced it with my new password. When I try to send a message I get the popup “Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com was lost in the middle of the transaction. Try again.” I also sometimes get the message “Login to server imap.gmail.com with username ……….@gmail.com failed” Under saved logins the entry for my gmail account is: Oauth://accounts.google.com (https:mail.google.com/) with my gmail address as username, plus the password, which is accepted by my phone and tablet. I have two email accounts, the other works normally, but with the gmail account instead of the cursor showing it is the hourglass. I also How can I restore normality
