I’d like to give everyone a somewhat complete update on this feature request.
The feature “Undo Send” has been available on Outlook.com for a while now. With it, you can set a small delay of up to 10 seconds when sending all your email messages.
Additionally, we plan to make available a bigger feature that is along the lines of “Schedule Send”. At the moment, I cannot provide a time estimate for when it will show up for you. However, we’re very excited and hopeful :)Jean-François Normand commented
I very often use the "Cancel" button after I send a message... By chance I did a test before working with the beta! This could have gotten me in big trouble.
Also, it is still impossible for me to drag messages to other folders, I lost that function a while ago for an unknown reason.Jean-François Normand supported this idea ·
