I found the following warning message on my Exchange 2007 server, the event ID is 12018. &nbsp;I have applied an updated SSL cert but this old cert still showing on the log, what should I do to get rid of it. &nbsp;I have checked the OWA, the SSL cert is updated.<br />

The STARTTLS certificate will expire soon: subject: exchange.company.local, hours remaining: KI098PMB83BD1AA9LE93F8B691<wbr />E9GT47H8C1<wbr />BEF7. Run the New-ExchangeCertificate cmdlet to create a new certificate.
