As long as the recipient has not yet read an email, you can call back the sent email in Outlook..
In hectic everyday life it can happen that you send an email that contains errors, is not very tactful or was sent to the wrong recipient. You can retrieve such a message in Outlook. However, there are two prerequisites: the recipient must not have opened the message yet and the e-mail must have been sent and received on the same Exchange server. If the above requirements are not met, you will unfortunately not be able to retrieve the e-mail in Outlook. In addition, the callback function is not available in the Outlook mobile app.
