Hi bas,

From my understanding, OWA 2007 doesn't support S/MIME. But it can show the message body for clear-signed message. While the attachments won't be shown. OWA 2007 SP1 Beta2 supports S/MIME and you will be able to view the full content of the clear-signed message with the S/MIME active control installed. Event if you doesn't install the S/MIME active control, you can view the body and attachments of a clear-signed message in OWA 2007 SP1 Beta2.

The situation you describe is more like an opaque-signed message or encrypted message.
