Cannot open encrypted email in outlook

Hi,

I have outlook 2010.  I have received an email from someone that I cannot open.  I think it is encrypted.  The mail message has a little padlock next to it.  When I try to open it I get "Cannot open this item. Your Digital ID name cannot be found by the underlying security system".  I have also tried to open the email on another computer also using outlook 2010 and connected to my mailbox.  Same problem.  When I open it in a browser based email program I get an empty email and an attached file smime.p7m (which I cannot not decrypt).

Should the email sender have sent me a key to install first?  How do I open this email?

Get a free trial of http://www.cryptigo.eu/p7mViewer/Download/
That will tell you what it was encrypted to (it is not possible to send a smime.p7m without having a certificate to encrypt to)

Microsoft had a hot fix for opening .p7m files. Read this and see if it applies:  http://support.microsoft.com/kb/913966

The title says "users cannot see attachments that have the .p7m extension in outlook"
But I cannot even open the email to be in a position to see the attachment... I can only see the attachment when I open the mail in a web browser.  I have downloaded the attachment on another computer and it seems like an encrypted file.  Also, I have tried to open the email on a totally different computer with the exact same result.
