First of all, never access the Outlook or Redemption object models from a
background thread. Outlook and MAPI are designed to work on the main thread
and accessing those object models will hang or crash Outlook. If you must
use a background thread either synch it to the main thread context or
marshal it to the main thread before calling the object model, or get the
object data as strings or whatever and use those in the background thread.
If you have an item that has been saved and has an EntryID you can use
RDOSession.GetMessageFromID() with the EntryID to get an RDOMail item from
an Outlook item. The RDOMail item can be cast to a specific type such as
RDOTask if needed.
For Outlook 2007 you can use the PropertyAccessor object of the Attachment
object to find an embedded attachment. For Outlook 2003 you'd need to use
Redemption. You want to look for the presence of one or both of these
properties:
PR_ATTACH_CONTENT_ID 0x3712001E or "urn:schemas:mailheader:content-id" or
"
http://schemas.microsoft.com/mapi/proptag/0x3712001E"
PR_ATTACH_CONTENT_LOCATION 0x3713001E or
"
http://schemas.microsoft.com/mapi/proptag/0x3713001E"
If either of those properties is there it's an embedded attachment.
