MSDN says this of the MAPIFolder interface (Outlook programming with WPF):

This interface is deprecated; do not
use this interface. Instead use the
interface Folder to access all method,
property, and event members of the COM
object Folder.

I am trying to get the Drafts folder like so:

Outlook.MAPIFolder oFolder = olNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderDrafts);

How do I do the above without using the MAPIFolder (which is deprecated)?
I guess I don’t understand what MSDN is saying (using the Folder interface to access all method etc)

    You simply cast it to Outlook.Folder, i.e.

    Outlook.Folder oFolder = (Outlook.Folder) olNS.GetDefaultFolder( Outlook.OlDefaultFolders.olFoderDrafts)

    Admittedly, the MSDN is rather unclear there. You can think of the Folder interface as a wrapper around the MAPIFolder, with additional support for events.

    As I sidenote, I would take the whole ‘deprecated’ thing with a grain of salt. I’d bet MAPIFolder is here to stay, at least for a couple more versions of Outlook.
