Recall an Email Message You Sent
 

With message recall, you can retrieve a message you sent from the recipient’s mailbox if they haven’t yet opened it. For example, if you forgot to include a piece of information, you can try to retract the message and then send another one with the missing information. Message recall is available after you click send and is only possible if both you and the recipients have a WorldPosta mail account in the same organization.

How to Recall a Message:
 

1. In the folder pane on the left of the Outlook window, choose the Sent Items folder.

2. Open the message that you want to recall. You must double-click to open the message. Selecting the message so it appears in the reading pane won’t allow you to recall the message.

3. From the Message tab, select Actions, then select Recall This Message.

Note: If you don’t see the Recall This Message command, you probably don’t have an Exchange account, or the feature isn’t available within your organization.

4. Click Delete unread copies of this message or Delete unread copies and replace with a new message, and then click OK.
