I am extracting email metadata/properties and other info from within PST and MSG files. We store this in a database for ease of querying etc.
One of the most important properties we extract from each item is the EntryID (PR_ENTRYID). We use this to uniquely identify and check that we have the right item when we go back into the PST later to locate the original item.
I get the EntryID for most items from the MessageInfo before getting the MapiMessage.
The problem is that I can find no way to get the EntryID of embedded email attachments. That is, attachments with MapiPropertyTag.PR_ATTACH_METHOD = = 5. Is there any way to get this EntryID?
Ideally the PR_ENTRYID would be available in the MapiMessage Properties.
