Hi Ben,
Thank you for your reply.
In my policy I have used Lookup certificate by name.What if i want to get to know all the certificates details which are going to get expire.Is there any way i can list them out.
2.Using notafter i am getting the datetime of expiry of the certificate but is there any way to calculate the difference between two dates so as to make email alert using policy just before 15 days of expiry.
