Hello,

We are running an Exchange 2016 Server (Version 15.1 ‎(Build 2242.4)‎.

I found that the self-signed certificate has expired. 106958-1.jpg

There currently is no impact because I believe IIS & SMTP is being handled by the UCC Wildcard certificate purchased via Go Daddy.

I need to renew the expired self-signed certificate just to ensure all stored certificates are valid. Could you furnish recommended steps on how to accomplish this.

On a related note, when multiple certificates are assigned to SMTP, which is the server "using" for communication?

Thanks in advance.

Regards,
Rudy
