Extracting property "Hidden" and property "ReceivedDate" for a .msg file

[ullid72]

Hello,
due to issues with dependencies with higher level libraries, I am using OpenMCDF directly to read and parse an .msg file (read per filepath)..
i am stuck with 2 things:

1. retrieve the correct "Received Date" for the mail
2. retrieve the information "Hidden" for attachments (currently i am solving this via file name and mime type, but...)

any help is appreciated,
Ulli
