    Digital Signing (Office XP)

    I created a digital signature using the standard Office "SelfCert" tool. When I open (for the first time) a file (in my case: EXCEL) I get the normal message that the file is signed (but not trusted as there is no root certificate) and I can check a box to "Always trust" files signed like this.

    When I test this on someone else's PC, I get the same behavior but the "Always trust" checkbox is grayed-out (disabled)... that surprises me as I had hoped that my signing would help colleagues to use my tools without getting a macro-security message all the time.

    Anyone who can tell me why this check-box is disabled?

    Thanks,

    Erik Jan

    I don't know the answer, but here is a "guess".

    In order to "Always trust" a certificate you must already trust the certificate authority that issued that certificate. You obviously already trust your own SelfCert authority, but this is not visible to users of other computers so they cannot trust certificates it has issued.
