When I try to import such certificate I get "Only self signed CA cert can have identical sub and issuer fields" error.
The certificate is not from CA server so I don't have "Back up CA" option as described here:

I'm aware of this discussion but it's for SAML and it doesn't give answer to basic question as stated in this sbject:
https://live.paloaltonetworks.com/t5/general-topics/quot-only-self-signed-ca-cert-can-have-identical...
So how can I import a certificate with same subject and issuer field but is not marked as CA? It's a self signed certificate from MS Exchange server which is required for decryption.
