Ensure you're using the desktop version of Microsoft Outlook, as the recall feature is not available on mobile or the web app.
In the navigation pane, locate and click on your Sent Items folder. This is where you'll find the email you want to recall.
Find and double-click the email you wish to recall. It will open in a new window.
With the email open, click on the File tab located at the top left of the window. A dropdown will appear; choose Recall This Message.
A pop-up window will appear, offering two options. Click OK to confirm your recall action.
