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,
