Note: Before you run netmon, please contact an engineer on the support team so netmon on can be started on the cas server. The netmon trace needs to happen simultaneously
Step 6: Gather the ETL Log files & the capture files from Netmon
Note: Outlook generates a new ETL file each time you start Outlook with logging enabled. Therefore, it is important to control the repro scenario so you know which log file(s) to collect from the computer. Please don’t copy all the ETL files in the Temp folder.
 The log files are generated in the following format:
 OLKRPCLOG_<month>_<day>_<year>_<hour – 24 hr clock>_<minutes>_<seconds>_<index>.etl
 For example: OLKRPCLOG_09_06_2008_17_35_47_1.etl
Gather and upload the logs/trace files to Microsoft for analysis
