Use this method to create a memory-mapped file for the message content. This allows for fast scanning of the content in memory. The memory is mapped using the MapViewOfFile function.

Call IMailMsgProperties::UnmapContent for each pointer you successfully receive using IMailMsgProperties::MapContent.
