Microsoft still can’t make Windows 11’s New Outlook work offline because it refuses to go native

AI-summarised brief · reviewed before publication

Microsoft is struggling to make Windows 11's new Outlook work offline due to its web-based approach. The new Outlook is a web app that loads Outlook.com in a WebView2 container, similar to opening Outlook in an Edge tab. A recent update has added the ability to attach files while offline, a feature that has been available in the classic Outlook desktop app. The update also allows users to access more emails offline, with options to save up to 1 or 2 years of email on their device. Microsoft's refusal to create a native app is hindering the development of full-fledged offline support. The new features are rolling out widely, but the app still consumes more disk space compared to Outlook Classic.

💡 Why It Matters

  • · Microsoft's inability to deliver seamless offline support undermines the reliability of its enterprise email product.
  • · Limited offline capabilities can hinder productivity in areas with poor internet connectivity.
