I am getting Error Event Id 12016(There is no valid SMTP TLS certificate for the FQDN remote.domain.com)
This certificate is expired when I tried to check through Exchange shell and it is not self signed certificate.
The expired certificate was issued by CA installed on same server. I can see Certificate in the issued list but I can't renew it.
I tried to Generate request through Exchange shell and save it on desktop and When I try to import , it failed.
Please help me to find the proper procedure to install/create/renew the SMTP TLS certificate issued by CA.
Thanks In Advance
