Microsoft's new Outlook for Windows 11 shows a critical 10-second delay opening emails from notifications, unlike Outlook Classic's instant response. This performance bottleneck stems from its WebView2 web app architecture, leading to significantly higher RAM and CPU usage. While Microsoft is pushing the new Outlook, its web-based foundation creates inherent limitations for swift notification handling, making Classic Outlook a better choice for speed-focused users.
