How to fetch the conversation id from a .msg file using MAPIMessage
I’m trying to parse a .msg file. How do I get the conversation id?
I’m using org.apache.poi.hsmf.MAPIMessage
The structure of the MSG file format is described in the MSDN library, see [MS-OXMSG]: Outlook Item (.msg) File Format.
It is stored in the 0x0F030102
property – you can see if it is set in a particular MSG file in OutlookSpy (click OpenIMsgOnIStg button).
