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?

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.

This is an important and time critical email for me.  If anyone has some personal insight, it would be very appreciated.

What Is Threat Intelligence?

Threat intelligence is often discussed, but rarely understood. Starting with a precise definition, along with clear business goals, is essential.

More notes:  My organization does not install digital IDs (that I know of).
I am using a university email system from (gmail for universities).

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)
