How to initialize a IMimeMessage object from IStream

Given an empty MimeMessage created with e.g. MimeOleCreateMessage function, how can I initialize it from an IStream / data buffer, which contains the complete message text?

From stackoverflow

• If I'm not wrong IMimeMessage returned by MimeOleCreateMessage supports IPersistStream stream then you have Load & Save methods.
