New to Log Parser

I am having an issue with the iPhone & Office 365 where the meeting organizer receives multiple responses from an attendee.  In a Microsoft KB it was suggested to use Log Parser and run this query:

/* Query to find MeetingResponse commands by user device */
SELECT COUNT(*) As Hits,
EXTRACT_VALUE(cs-uri-query,'DeviceType') AS DeviceType,
EXTRACT_VALUE(cs-uri-query,'DeviceId') AS DeviceId,
REPLACE_STR(TO_STRING(EXTRACT_PREFIX(EXTRACT_SUFFIX(cs-uri-query, 0, '_SmtpAdrs:'), 0, '_')), '%40', '@') As User,
EXTRACT_VALUE(cs-uri-query,'Cmd') AS Cmd
FROM '[LOGFILEPATH]' 
WHERE cs-uri-stem LIKE '%Active%' AND Cmd LIKE '%MeetingResponse%'
GROUP BY DeviceType,DeviceId,Cmd,User
ORDER BY Hits DESC 

However, I get a message saying it is not recognized as an internal or external command, operable program or batch file. Thus, am I doing something wrong?  Do I need some sort of phrase, prefix, and/ or suffix when running the query?
