    I don't know anything about this method but the error itself indicates you are using query options that are invalid. Looking at the documentation for the method I notice it is inconsistent as to what is allowed making this really hard to figure out. However it does mention the AreQueryOptionsSupported method that you can call to confirm that the options you want to use are valid for the given folder. I recommend you call this method with your configured options first and see if it returns success. If it says they are valid then the subsequent call should be fine. If not then your query options are incorrect for the folder you're trying to use.
