How to recall an email in Microsoft Office Outlook?

To do that please follows the instructions;

Double click the email from "Sent Items" -> Click "Other Actions" -> Click "Recall This Message" -> Select desired options like "Delete unread copies of this message" -> Click "OK" -> Wait a while to see the result email from the mail server

* If one of recipients read this email, you cannot recall it. Therefore, you should receive the fail info message from the mail server after recall request.

That's all
