I have an expired self-signed TLS cert and I'm getting loads of 12016 errors from the transport service.
Google has given me the command "Get-ExchangeCertificate -thumbprint "our thumbprint here" | New-ExchangeCertificate" , the to click yes to overwrite the existing SMTP cert. I wanted to doublecheck that this won't mess up our extermal cert that used for OWA. Am I safe here?
