How exactly did you call CreateItemFromTemplate?
RDOMail.Sent can be set only before the message is saved for the very first
time, otherwise you will get the MAPI_E_COMPUTED error.
If oyu are using Redemption, why do you even need
Namespace.CreateItemFromTemplate?
Something like the following will do the trick:

set Session = CreateObject("Redemption.RDOSession")
Session.MAPIOBJECT = Application.Session.MAPIOBJECT
set Folder = Session.GetDefaultFolder(...)
set Msg = Folder.Items.Add
Msg.Sent = true
Msg.Import(..., olMsg)
Msg.Save

Hello,
I want to load a stand alone MSG file (on disk) into Outlook. To do this,
I
tried using the CreateItemFromTemplate() function. This always return
"invalid argument" when trying to pass a folder as the second argument. To
go
over this, I tried ignoring the second parameter. Now, the MSG loaded into
the DRAFTS folder. Another time, I went over this by moving the mail to
the
Inbox. Also, the Message Dates changed (creation / Delivery). These dates
can
be updated.
The problem now that the MSG appaers as "not sent". I tried setting the
(0xF402) property using OutlookSPY, but that didn't change anything. Also
Redemption.RDOMail.put_Sent() returned "0x8004011a"!!!!!
Any help?
