File Extension P7M

The P7M file type is primarily associated with 'PKCS #7 MIME Message'. See Section 3.2 in RFC 2311. This is basically a secure E-mail file sent in encrypted form. If everything is set up properly your E-mail program should have downloaded a public key necessary to decrypt the file.

When windows gives you an error message saying that it
"Cannot open P7M files", this means either:

A. You need to identify a program that can open the file
B. Or your registry may be damaged

In both cases it is strongly recommended that you
run a free scan for registry errors.
