urgent help with troubleshooting SMTP TLS configuration on IIS - to start in next 2 hours

We have a Windows IIS SMTP server that started rejecting emails due to TLS misconfiguration. We confirmed certificate issue, have other servers configured correctly, so need assistance fixing the configuration issue or certificate to match other servers (that are using a wildcard certificate). The issue may be because host-specific certificate is installed rather than a wildcard one like on other servers

sample diagnostic log:

STARTTLS command works on this server

Cannot convert to SSL (reason: SSL connect attempt failed because of handshake problems)

Cert Hostname DOES NOT VERIFY ([url removed, login to view] != )

You will be given remote access to the server to work with us on this issue.
