I am trying to use NXlog CE to forward Exchange 2016 message tracking logs via syslog. I am trying to use the example shown here

https://nxlog.co/documentation/nxlog-user-guide#exchange_transport_logs

When I create the conf file and attempt to run it the service starts but there are several errors logged in the nxlog.log file.

My config file is as follows

Panic Soft
#NoFreeOnExit TRUE

define ROOT     C:\Program Files (x86)\nxlog
define CERTDIR  %ROOT%\cert
define CONFDIR  %ROOT%\conf
define LOGDIR   %ROOT%\data
define LOGFILE  %LOGDIR%\nxlog.log
LogFile %LOGFILE%

Moduledir %ROOT%\modules

Pidfile   %ROOT%\data\nxlog.pid

            $EventTime = parsedate(${date-time});

The errors logged in the nxlog.log file are as follows.

I have yet to come across a working example of how to forward exchange logs and was hoping someone may be able to assist. I cant see what i am missing here.
