Hi all,
I think this might be related.
I have noticed that to make "Save replies and forwards in the folder of the original message" to work you must have
"Sent message in sent folder" must always be on.

This to me seams wrong but you if you are correct that first it goes to the sent folder and then to the folder you wanted then I suppose it makes some sense.
To me the first flag should not be needed and it should just go straight to your original folder in the sending process.

As you have indicated for the problem observed the draft flag must be set on the way through.
Maybe a look at how this whole area works may clear it up and solve it.
