The parameter is optional. Have you tried to call the Add method with a default value? Does it work? — Eugene Astafiev, Mar 16 '15 at 15:02

You need to differ Outlook and Redemption objects.

It looks like you need to use the GetRDOObjectFromOutlookObject method of the Session class (Redemption).

 set Session = CreateObject("Redemption.RDOSession")
 Session.MAPIOBJECT = Application.Session.MAPIOBJECT
 set redItem= Session.GetRDOObjectFromOutlookObject(mail)

The Add method of the Items class creates and returns a new Outlook item in the Items collection for the folder.

I do not see any Outlook Object Model objects in the OP's code. – Dmitry Streblechenko Mar 18 '15 at 05:40
The code was added later, i.e. the poster edited the post. FYI The Items property of the Folder class exists in the Outlook object model. – Eugene Astafiev Mar 18 '15 at 08:22

Most likely the folder variable is null - if the folder does not exist, retrieving it by name (RDOFolder.Folders.Item("foldername")) will return null:

RDOSession session = new RDOSession();
RDOPstStore store = session.LogonPstStore(newpstpath);
RDOFolder folder = store.IPMRootFolder.Folders.Item(directoryEmlFile);
if (folder == null) folder = store.IPMRootFolder.Folders.Add(directoryEmlFile);
RDOMail mail = folder.Items.Add("IPM.Note");
