On the recipient's computer, either by rule or by action of the recipient, both messages are moved to the same folder. The original message and the new message are both available to the recipient. This occurs regardless of the Outlook configurations and the read status of the message. If the recall message and the original message exist in separate folders, the recipient receives a message that states a recall attempt failed. On the recipient's computer, either by rule or by action of the recipient, the original message is moved out of the Inbox to another folder and the recall message remains in the Inbox (or it is moved to another folder also).
You recall the original message and replace it with a new one.
However, the message remains in the recipient's Outlook folder. Note: If the original message is marked as read (viewing in the Reading Pane isn’t reading in this scenario) when the recall message is processed, the recipient is informed that you, the sender, want to delete the message.
