Outlook allows you to recall an email (or to withdraw or unsend it) only if both you and the recipient are using Office 365 or Microsoft Exchange email accounts within the same organization. This option is available starting with Outlook 2007 and it is not available for Outlook on the web.
How to recall an email in Outlook
If you want to withdraw an email that you’ve already sent, you can go to your Outlook Sent Items folder, open (double-click) the email message that you want to be recalled, go to the Message tab, select Actions, then Recall This Message:
You can choose to delete the unread copies of that email or to replace the email message with a different one.
Please note that, if the recipient already got to read your email, you can not delete or replace it.
