I'm adding a signature line and when I right clicked and then clicked sign, "No usable signing certificate available. Please insert your smart card or contact your administrator to obtain a signing certificate" and then that notification is showed up. Idk about the digital ID set up but I have used the signature line before then signed it, and it just worked fine.
I was able to fix this by importing the certificate via the Internet Options / Content / Certificates interface, into the following three stores: Personal, Trusted Publishers, Trusted Root Certification Authorities.
Previously, I'd imported the certificate into all three locations via "Manage computer certificates", for machine-level, and "Manage user certificates", for user-level, but although the certificate showed up in all six locations (three locations machine, three locations user), Excel didn't recognize it. But going through the Internet Options UI did the trick.
