Since I am an iPhone and Mac user and spend a lot of time each day on both, I was so happy to discover these tips to undo my most frustrating tech mistakes.
How to Un-send an Email in Microsoft Outlook
While not as foolproof as Gmail, Outlook does allow you to recall messages that have previously been sent. You can either delete the message entirely (for those who haven’t already opened it) or replace it with an error-free email (typos, begone).
To enable Recall, go to “Navigation Pane,” then “Sent Items.” Open the message you want to recall or replace and on the “Actions” menu, click “Recall This Message.” Then “Delete Unread Copies of This Message.”
How to Un-send a Text on an iPhone
Though you can’t un-send a text once it’s gone out, you can stop one that’s in the process of being sent (i.e., the little gray bar is still loading). Here’s how to do it: Once you notice your flub, immediately put your phone on Airplane Mode. When the text fails to deliver, delete the message. (Warning: This only works for texts sent through iMessage and for texts that are sending particularly slowly.)
To enable Airplane Mode, go to “Settings,” then “Airplane Mode,” then switch to “On.”
