Recall or replace an email message that you sent

With message recall, a message that you sent is retrieved from the mailboxes of the recipients who haven’t yet opened it. You can also substitute a replacement message. For example, if you forgot to include an attachment, you can try to retract the message, and then send a replacement message that has the attachment.

Message recall is available after you click Send and is available only if both you and the recipient have a Microsoft 365 or Microsoft Exchange email account in the same organization.

To recall and replace 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 > Recall This Message.

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

If you’re sending a replacement message, compose the message, and then click Send.
