Note: Some versions of Thunderbird will report Command error 12 (but everything seems working) This is due a missing support of ID Command by the exchange server (a command send by the Thunderbird client).
Solution: Go to Tools > Options > Advanced > General tab or Menu icon > Options > Options > Advanced > General tab click on 'config editor' button. it will tell you to be careful :) In top search type: send_client look for this line: mail.server.default.send_client_info; Value = true Double click on that line to toggle TRUE to FALSE It will stop Thunderbird from sending the "ID command". the error seems to be happening with some servers that claim to support that command but return an error when it is used. Close window - top right X click on OK Restart Thunderbird.
