How to set up ‘undo send’ to cancel emails in Outlook

One could say that the best way to undo an email message is to not send it at all. However, we send a lot of emails in the daily basis, accidents will happen, and many times you don’t realize your message is incorrect until you click the send button.

Google’s Gmail was the first email service to include an “undo send” button giving you 30 seconds to cancel an email, then Microsoft followed by adding the same feature to Outlook.com, but for those using the Outlook desktop app there isn’t such feature. Though, you probably didn’t know, but the Outlook desktop app actually include settings you can configure to delay sending a message to mimic “undo send”.

In this guide, you’ll learn the steps to configure a rule in the Outlook desktop app to easily undo sending an email message, and you’ll learn the steps set up “undo send” in Outlook.com.
