Microsoft has officially begun phasing out the legacy OneNote desktop application in favor of its modern Windows 11 counterpart, marking a significant shift in the company's note-taking strategy. This transition, while gradual, signals Microsoft's commitment to unifying its productivity ecosystem under the Windows 11 umbrella.

The End of an Era: Legacy OneNote Deprecation

The legacy OneNote app (often called OneNote 2016) has been a staple of Microsoft's productivity suite since its inclusion with Office 2016. However, as of 2023, Microsoft has:

  • Stopped feature development for the legacy version
  • Removed it from Office 365 installations by default
  • Begun redirecting users to the modern OneNote for Windows 10/11

"This change allows us to focus our efforts on delivering innovative features in one unified application," explained a Microsoft spokesperson in a recent blog post.

Key Differences Between Legacy and Modern OneNote

While both versions share core functionality, several important distinctions exist:

Feature Legacy OneNote Modern OneNote
Interface Ribbon-based Fluent Design
Integration Office 2016 Microsoft 365
Sync Speed Standard Optimized
Pen Support Basic Advanced
Dark Mode Limited System-wide

Why Microsoft is Making the Switch

Three primary factors drove this decision:

  1. Technical Debt Reduction: Maintaining two codebases was becoming increasingly costly
  2. Feature Parity: The modern app now matches legacy functionality
  3. Ecosystem Alignment: Better integration with Windows 11 and Surface devices

What This Means for Different User Groups

Enterprise Users

Organizations with volume licensing can still access OneNote 2016 until October 2025, but Microsoft recommends beginning migration plans now.

Education Sector

Schools using Class Notebook features should transition before the 2024-2025 academic year for full support.

Casual Users

Most personal users will automatically receive the modern app through Windows Update, with notebooks seamlessly transferring.

The Future of Note-Taking in Windows

This transition aligns with Microsoft's broader vision for Windows 11, including:

  • Deeper pen and touch optimization
  • AI-powered features like ink-to-text
  • Tighter Teams integration
  • Cross-device synchronization

"We're investing heavily in making OneNote the ultimate digital notebook for the hybrid work era," said Panos Panay, former Chief Product Officer at Microsoft.
