To recall an email in Microsoft Outlook, you need to follow these steps (applicable mainly in Outlook for Windows with Microsoft 365 or Exchange accounts):

1. Open Outlook and go to the "Sent Items" folder.
2. Find and open the email you want to recall by double-clicking it.
3. In the open email window, click on the "File" tab.
4. Select "Info", then click on "Message Resend and Recall" and choose "Recall This Message."
5. You will see two options:
   • "Delete unread copies of this message" to remove the email from the recipient's inbox if unread.
   • "Delete unread copies and replace with a new message" to send a corrected email instead.
6. Check the box to "Tell me if recall succeeds or fails for each recipient" to receive notifications about the recall status.
7. Click "OK" to initiate the recall.

Important notes:

• Both sender and recipient must be using Outlook with Microsoft 365 or Exchange in the same organization for recall to work.
• Recall won't work if the email is already read, the recipient is using cached mode, forwarding externally, or using a mobile device or webmail.
• The recipient may get a notification of the recall attempt, especially if it fails.

If using the new Outlook interface with a simplified ribbon, the recall feature might be absent; switching to Classic Outlook is recommended for this functionality. This recall method works best within organizational Microsoft 365 environments and is not foolproof but can be very useful in certain cases to retract sent emails quickly.
