Besides the modulus not being prime, your signature is greater than your
modulus, which should never happen.
Either your cert is totally bogus/corrupted, or your build of openssl is
messed up. Probably the latter, because you probably built it yourself
while the MS Outlook cert manager came to you already built. You should
check your build tools and configuration.
