Outlook AdvancedSearch with Categories throwing parameter exception

Question

I'm getting an ArgumentException when I call AdvancedSearch (Could not complete the operation.  One or more parameter values are not valid.).  Here is the code:

        Search CreateSearchFolder(Store searchStore, MAPIFolder searchFolder, string category)
        {

            string scope = searchFolder.FolderPath;
            string criteria = "\"urn:schemas-microsoft-com:office:office#Keywords\" = '" + category + "'";

            searchStore.Application.AdvancedSearchComplete += new ApplicationEvents_11_AdvancedSearchCompleteEventHandler(Application_AdvancedSearchComplete);
            searchStore.Application.AdvancedSearchStopped += new ApplicationEvents_11_AdvancedSearchStoppedEventHandler(Application_AdvancedSearchStopped);

            return searchStore.Application.AdvancedSearch(scope, criteria, true, category);

        }

The value of scope is: "\\\\Archive-2012\\Inbox\\Analytics"

and the value of criteria is: "\"urn:schemas-microsoft-com:office:office#Keywords\" = '.A'"

Any help appriciated.

I think you should pass scope enclosed in ' ... '
