Hello. I am attempting to sign VBA in a Word file. I imported a PFX file to my Personal Certificates (via edge://settings/privacy). I also confirmed the import via certmgr.msc (it’s there under Personal…Certificates)

This PFX is used for a server TLS which I maintain (in addition to the server leaf cert, the PFX contains the intermediate and root self-signed organization certs…both are pre-loaded in everybody’s Windows Trust Stores).

So my thinking is to sign the VBA with this server PFX then via chain of trust, the VBA signature will be verified when walked back to the root by the client.

Anyway, in MS Word…Developer….Tools…Digital Signature….

when I choose “Sign as” and Choose button, I get the “No usable signing certificates are available”

Anybody have any ideas? I’ve googled all over and all day.. Does the”Certificate intended purpose” have anything to do with it not being available?

thank you so much for reading.
