New M365 Copilot Design and User Experiences

I am little late in posting this, but at the end of May 2026, a new M365 Copilot design was launched.  

Here is a summary of those changes:

• Task-aware prompt experience: The prompt area evolves from a simple text box into a workspace that adapts to the task being performed, surfacing relevant tools and controls directly beneath the prompt.
• Larger, more expressive prompt surface: Users now have more space to describe their needs and work naturally with Copilot.
• A single Copilot entry point across Microsoft 365: Microsoft is creating a common Copilot entry experience across Microsoft 365 applications that can suggest relevant actions based on context.
• Progressive disclosure of capabilities: The interface begins with a clean, focused design and reveals additional capabilities only when they are needed.
• Simplified navigation: A new expandable and collapsible left navigation pane provides access to agents, conversations, and history while preserving workspace focus.
• Improved work continuity: Shared pinning capabilities and expanded session recall make it easier to return to ongoing work and previous conversations.
• Faster and more responsive experience: The redesign focuses not only on appearance but also on improving responsiveness and overall performance.
• Greater emphasis on output quality: Microsoft states that the most important aspect of the experience is no longer the interface itself, but the quality of the output including tone, structure, readability, usefulness, and trustworthiness.
• More connected and adaptive Copilot experience: The redesign is intended to make Copilot feel like a connected system that moves with users across tasks, teams, applications, and workflows.

Probably, the biggest change customers will see is the Work/Web tab is now gone.
