Hi,
We have protected all our Office add-ins with a digital certificate
generated by our systems team. Now the certificate has expired and out IT
department created a new certificate with the same name and DN. still my old
excl files throw error about the certificate expiry.

Is there any way I can use the old signed excel files without re-signing
with a new certificate?
Is there any way that we can renew the certificate, so that existing files
will work without re-signing?


Best Regards,
Venkataramana

You renew your certificate with the issuing authority (Verisign, for
example).

If these were self-generated certificates then I do not know ... I think you
would have to re sign things with the new one.
