Exchange Delegation Certificate expired
We just installed a new Exchange 2019 CU14 server in an exhcange 2013 organization, to upgrade it, and when connecting to the EMC we got the warning that the "Exchange Delegation Federation" certificate is expired.
How can it be that a new exchange server has self-signed certificate already expired ?

Exchange Delegation Federation certificate is a self-signed one and typically gets renewed automatically.
If the certificate does not gets renewed automatically, please check the below link for manual renewal: (The solution steps are same for Exchange Server 2019)

my question was more related to understand how come that the new server installation came out with an already expired self-signed certificate.
