Upgrading to version 3.2 of CMN appears to break logging functionality. The log4net.config files are not listed in the relevant directories for the DominoFreeBusyService and ExchangeFreeBusyService
This is caused if the installation did not complete correctly
To resolve this issue, uninstall CMN and then reboot the server and reinstall CMN. The log4net.config files should now exist in the correct locations. Logging will start working with the default settings
