Left over certificates

[Gunna]

I have a number of CA Exchange certificates in my issued certificates. They

are all expired. They have the message of "The certificate has a nonvalid

digital signature" Is this becuase they are expired?

Should I revoke expired certificates?

Hi,

The nonvalid signature error is due to them being expired.

There is no reason to revoke an expired certificate. By definition, a

revoked certificate is a certificate that must be terminated before its

normal expiration.

HTH,
