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

If you want to parse MSG files using OpenMCDF directly, you'll need to read up on the specifications here:
