Some embedded messages don't have a PR_CONTENT_ID property in the attachment
object. That's especially true if the item is an RTF email. Two other
properties also need to be checked for a complete solution:
PR_ATTACH_CONTENT_LOCATION (0x3713001E, a PT_STRING8 property that if it
exists means an embedded attachment) and PR_ATTACH_METHOD (0x37050003, a
PT_LONG property that if it equals 6 means an embedded attachment).

The method Michael suggested is the one you need to use to determine whether
it's a "real" attachment.
