How to recall an Outlook message
1. Go to your sent items folder in Outlook.
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. Select Actions > recall this message.
4. Select Delete unread copies of this message or Delete unread
copies and replace with a new message, and then select OK.
After submitting a recall request, usually less than 30 seconds later, you will get an email notification with the subject "Message Recall Report for message [original message subject]".
Select the View Message Recall Report link to view the report in your browser. If you’re prompted, log in with your mailbox credentials to view the report.
Recall actions are usually quick, regardless of how many recipients are involved. But if the recall request can’t be executed right away for some reason (e.g., the recipient’s mailbox is temporarily unavailable) we'll continue to retry for up to 24 hours before marking the recall as failed.
