Today I have started getting an error when opening thunderbird. "Sending of password for user did not succeed. Mail server responded: Bad Login" It then goes to connection to server timed out, and login to server failed with an option to retry, enter new password, or cancel. Non of which resolve the issue. Thank you in advance
