i can not sync my account
Account syncing is a client side feature, not server. In TS3 just go to your options and make sure you are signed into your myTeamSpeak account from the myTeamSpeak section. When you go to things like manage bookmarks if you are in advanced view you will see your bookmarks that are synced on the top and local on the bottom in the left half of the window. You can also sync your identities.
