Look at the MessageClass of the email. A signed email would have something
like "IPM.Note.SMIME.MultipartSigned", or some variant of "IPM.Note.Secure".
Look for MessageClass's like that.

Guys

I am developing a app using C#, VSTO and Office 2003. I have a
requirement where I need to verify if the email is encrypted or not -
meaning it has a certificate attached or not. I dont even need to know
the details of the cert or the validity - just if an email is
encrypted or not.

Is there a way to get to achieve this through the Outlook Object Model
or is there any other API i need to know of
