Exchange certificate expiry event 12018 not logging.

Hi All,

We have  Exchange 2013 CU9 installed on Windows server 2012 R2 Standard. GoDaddy certificate installed on this server is about to expire in next 4 days but there is no event logging for this certificate expiry. When I check the other Exchange 2013 servers I found MSExchangeTransport event 12018 gets logged while a certificate is about to expire. any suggestions.
