It's not surprising; me too use S/MIME only occasionally to verify
emails from certain senders :-)

For this particular interop issue, I am curious what is causing the
difference. S/MIME encrypted messages are typically in the
enveloped-data format, which means that the encrypted content is simply
treated as an attachment.
If you have access to an MUA interoperable with Outlook, could you
compare the message structures for the success/failure cases?
