Once it's sent, it's sent, and the sender can do absolutely nothing to prevent any recipient from reading the email. There is no built-in feature to the protocols that make email work (specifically, SMTP) to "undo" a send.

There's literally nothing else you can do. To "permit" the recall, just delete the message from your mailbox. If the recipient is using a different type of mail server (e.g., gmail, or anything else), the recall is literally nothing but a plain text message. It only works if the recipient's mailbox is on a Microsoft Exchange server and they are using the Outlook client. If not, well, you might not be so concerned about message recall.This email "recall" feature is not a standard feature of all email clients. If you can hold off making a fool of yourself until then, the new message recall will help. Given the number of clients involved (especially Outlook desktop) and the complexity of rolling out new functionality across Office 365, it’s unlikely that we will see the new recall function much before the second quarter of 2020. The work to build a new recall function is ongoing with no committed dates.
