Microsoft new Outlook takes 10 seconds to do what Outlook Classic does instantly
TL;DR
Microsoft's new Outlook for Windows has a significant delay in responding to email notifications compared to the classic version. The new Outlook, built on WebView2, is designed to replace the older Win32 app but has faced performance issues.
✦ Why It Matters
Engineers should consider performance trade-offs when transitioning applications from native to web-based frameworks.
Key Takeaways
- Evaluate performance metrics before adopting new frameworks.
- Test user experience with notifications in web apps.
- Monitor feedback during software transitions.
- Prepare for potential delays in user adoption.
Full Summary
Outlook for Windows has two versions: the classic Win32 desktop app, known for its speed and power, and the new Outlook, which is built on WebView2, essentially a web browser interface for Outlook.com. Microsoft aimed to modernize the email experience by transitioning to a web-based application, but this shift has led to performance issues, particularly with notification handling.
Users have reported that clicking on a notification for a new email can take up to 10 seconds to load, a stark contrast to the instant response of the classic version. Although the new Outlook has improved its launch speed, the notification lag remains a significant drawback.
Microsoft has delayed the mandatory transition to the new Outlook for enterprises, indicating that it recognizes the app is not yet fully optimized for all users. This situation underscores the challenges of balancing modernization with performance in software development.
