Microsoft is retiring the Windows Mail app in Windows 10 and Windows 11, and replacing it with the Outlook Mail app, which has the same layout and appearance as the outlook.com web-interface. It also brings several sought-after features, including the ability to block senders with one click, and also to report and block scammers. If you currently use the Windows Mail app (a blue and white envelope icon), I've created instructions on how to migrate and customize the new Outlook Mail app so it won't seem quite different. You can view, download, and print the instructions below. If you don't do this upgrade yourself, Microsoft will automatically upgrade you one day soon, and you'll be caught by surprise!
