A common cause of being unable to add your account to your device is your current password being too short. Please ensure your password is at least 8 characters long and try the process again. If this does not resolve the issue double check or reset your Google account settings in case you have unintentionally changed a setting. If you are still receiving an error please try the process again in a few hours or contact IT Help. It may be that your device does not support Google accounts.
