How Do I recall an E-mail in Microsoft Outlook?
This feature requires you to use a Microsoft Exchange account. Most home and personal accounts do not use Exchange. The recipient of the mail you want to recall must also be using an Exchange server e-mail account. If the recipient has already read the message, then the recall will fail for that individual.
- Within Outlook, open the message you want to recall or replace from within your Sent Items folder.
- On the Actions menu drop-down, click Recall This Message.

- Once you do, you will be prompted to choose between deleting unread copies or deleting them and replacing them with a new message. You can also choose to receive a notice on which emails were successfully recalled.

- Click Delete unread copies of this message. Click OK to complete the recall.
