Mailbox

You can recall or replace a message only if its recipient is logged on and using Microsoft Outlook and has not read the message or moved it from their Inbox.

To replace a message, you must send a new one. If you do not send the new Item, the original message is still recalled.

In the Navigation Pane, click Sent Items to switch to that folder

In the Sent Items folder, double-click the message that you want to recall to open it.

In the open message, click Other Actions in the Actions group, and click Recall This Message.
