Microsoft's new Outlook takes more than 10 seconds to open an email via notifications, while Outlook Classic opens instantly on Windows 11!
The funniest part? If I ignore the notification, open Outlook manually, find the email myself, and click it, I can finish faster than the notification flow.
It's all because Outlook for Windows is literally Microsoft Edge running Outlook .com in a browser window.
New Outlook runs through WebView2 with around 10 separate processes: GPU process, service worker, utility processes, manager, and more. It uses roughly 490MB to 636MB RAM while idle, compared to Outlook Classic sitting around 117MB to 148MB.
CPU usage is also worse: around 4% idle on new Outlook versus under 1% on Classic in my testing.
Microsoft shut down Mail and Calendar, keeps pushing enterprises toward this web wrapper, and still wants people to believe it is the future of email on Windows.
SHAME!
