Hi,
I understand you’re using the PKI Certificate Validation V3 MP for monitoring your PKI infrastructure and you have two questions. Let’s address them one by one:
Question 1: Is this MP still supported on SCOM 2022 /2025?
Yes, the PKI Certificate Validation V3 MP is still supported on SCOM 2022. I don’t have information about SCOM 2025. You may want to check the latest updates on the official Microsoft website for the most accurate information.
Question 2: How to get Email Notifications on all Certs “About to Expire” from Local Computer/Personal Cert Store for one Server?
Have you tried selecting the 'Expiring Certificates Group'?
