How to remove a Certificate from CA
We had a unexpected expiry of one of our certificates for external email access, as we tried to renew this we unfortunately renewed the CA Authority itself, and subsequently the owa certificate. I now need to remove the newly created CA certificate (as you can see in the pic attached).. anybody know how to do this? Ive search the local certificates on the CA and removed the later created. but its still in the list!.. My problem is any newly created certificates are created on the new CA Certificate, and not the old one, which is what is trusted by all the teacher laptops.
