Im getting the event warning message that STARTTLS cert self signed cert will expire soon. It directs to run the New-ExchangeCertificate cmdlt. I believe this is referring to the initial self signed cert created on installation and expiring in 1 yr.
We have installed a SAN Cert which includes the listed server. Why is this one not being used? It is not expiring soon.
Will I need to renew the self signed cert every year?
If so Can I run the Clone process to reup the cert for another year?
