I have followed the steps on how to enable S/MIME in OWA, I have downloaded and install the controls into IE, I can see the menu options to sign or encrypt, but if I try to sign an email I receive a message stating "No certificate was found. If you have a smart card-based certificate, insert the card and try again.". My SC is in the reader and I used it to log into webmail, but I am never able to tell it which certificate to choose.
Did I miss something in my server configuration?
I have tried this on Windows 7 and Windows 8.
I have not loaded Outlook onto my computers and played with that yet.
Thanks,
Mike
