How to remove a Certificate from CA

[PRicho]

Hi,

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.

Cheers!

You can't revoke a CA certificate, only renew it.

boo,

Am i correct in saying that new certificates are created from the New CA Cert, and therefor as our CA Authority isnt trusted users will need to install the latest CA Cert? even though that already have to old cert from the same CA

If we were to buy an ssl where would it be placed? we have OWA and we also use mail over http for outlook from home, these each have there own cert's so would we require 2 ssl's which are supplied from a trusted source? as these are filtered through ISA.

Any advise for our setup would be appreciated!
