S/MIME properties

R

Preface
I developed addin to outlook, based on VC++, MAPI, which the main focus is
S/MIME - Encrypt, Decrypt, Sign, Verify.

When I try to reply S/MIME email-(Encrypted and sign) , Outlook sets
automatically the options (Encrypt, Sign), after I send the reply email, my
addin got the reply email, and I try to get properties about attachments on
reply email(marked as S/MIME by outlook), MAPI returned warnings, invalid

I tried to change the message class to IPM.Note, and clear the S/MIME
options on property 0x6E010003.

And still, I didn't get info about attachments.

I think that outlook marked this email as S/MIME, and then it prevents from
my addin to gets info about attachments.

When I deselect S/MIME options, before I send it, it still does not work.

Has anybody know about other properties of S/MIME, or how to get info from
attachment.


Thanks
