Copilot Chat vsus. Microsoft 365 Copilot. What's the difference?
While their names sound similar at first glance, Microsoft 365 Copilot and Microsoft 365 Copilot Chat, they differ in several aspects. And more importantly: one is built on top of the other. What is Copilot Chat (Basic)? First things first. Microsoft 365 Copilot Chat is often simply called Copilot Chat. Copilot Chat (Basic) generates answers based on web content, while Microsoft 365 Copilot (Premium) is also grounded on users' data, like emails, meetings, files, and more. Since early 2025, Microsoft 365 Copilot Chat has been available to all users in organizations, becoming the entry point to AI assistance for many organizations. Copilot Chat (Basic) is the foundational Copilot experience available at no extra cost for everyone with an eligible Microsoft 365 plan, including: Microsoft 365 E3 / E5 Microsoft 365 A3 / A5 Microsoft 365 Business Standard & Business Premium Copilot Chat (Basic) is secured, compliant, and it does not required the full Copilot add-on license. Copilot Chat (Basic) is able to ground responses on: Public web content. Content explicitly shared or work data manually uploaded to the chat by the user. On-screen content or content displayed on-screen in apps like Outlook, Word, Excel, PowerPoint, and OneNote. When it comes to agents, Copilot Chat (Basic) offers these features: You can create your own declarative agents grounded on public web content with Agent Builder. You can use agents built by your org grounded on organizational data with the pay-as-you-go method. There are Microsoft prebuilt agents available like Prompt Coach, however Microsoft premium prebuilt agents like Researcher or Analyst are not included. The screenshot below shows how Copilot Chat looks and highlights its main capabilities. Note the Upgrade button, meaning this is not Microsoft 365 Copilot, but the Copilot Chat (Basic) experience. Note that EDP (Enterprise Data Protection) is available in Copilot Chat (Basic). What is Microsoft 365 Copilot (Premium)? Microsoft 365 Copilot (Premium) is a paid add-on license that builds on top of Copilot Chat and unlocks Copilot's full power. It is available for selected Microsoft 365 plans, including: Microsoft 365 E3 / E5 Microsoft 365 A3 / A5 Microsoft 365 Business Standard & Business Premium With a Microsoft 365 Copilot license, users get everything Copilot Chat (Basic) offers, plus much more: Data grounding: Microsoft 365 Copilot (Premium) includes Copilot Chat grounded on web and/or on user's Microsoft 365 data like emails, meetings, chats, and documents.

The integration includes features like Edit with Copilot allowing Copilot to adjust live your documents or email based on your prompts. Custom agents: It brings the capability to create your own declarative agents grounded in organizational data and/or web data. You can create agent either using Agent Builder or Copilot Studio. MS prebuilt agents: Premium prebuilt agents like Researcher and Analyst are included in Microsoft 365 Copilot (Premium). The screenshot below shows the Copilot chat experience for users who have a Microsoft 365 Copilot license. Note that EDP or Enterprise Data Protection also applies here How can I access Microsoft 365 Copilot Chat? Today, Copilot Chat is accessible via https://m365.cloud.microsoft or https://copilot.cloud.microsoft using your Entra ID (work or school account). One important difference in day-to-day experience: Users with a Microsoft 365 Copilot license typically see Copilot prominently surfaced across Microsoft 365 apps. Users with Copilot Chat only may not see it pinned by default on the Microsoft 365 home page. To improve discoverability, Microsoft 365 Copilot administrators can pin Copilot Chat via the Microsoft 365 admin center, ensuring that users can easily access it without friction. Especially convenient is that if you use the M365 Copilot Chat app on Windows, you can open Copilot using the keyboard shortcut Ctrl + C. What’s the difference? The differences between Copilot Chat and Microsoft 365 Copilot mainly come down to: Licensing Data grounding (web-only vs. personal work data) Integration depth within Microsoft 365 apps I’ve listed the key differences in the comparison below. 👇Top 3 Microsoft Copilot Features You Should Know – April 2026

Change Default for Copilot Automatic Room Rebooking Setting in Outlook?
My users with Microsoft 365 Copilot licenses have noticed a newer feature that automatically rebooks meetings with an alternate room if the selected room is unavailable. It appears that this setting is on by default and can be turned off on a per case basis when a new meeting event is being scheduled. Is there a way to turn it off by default and allow people to enable it when a new calendar item is being created instead? Here is what it looks like for me in Outlook. I can click on Edit from the new meeting window and turn it off for a single event. I haven't found a way to change that default behavior. Has anyone found a way to adjust this? Thank you!

Submitted by: Craig D. Evans Detroit, Michigan Executive Summary This proposal outlines a strategic redesign of Microsoft Copilot that transforms it from a collection of isolated chat instances into a unified, persistent, account based artificial intelligence assistant. The proposed architecture positions Copilot as the central intelligence that operates all Microsoft Office applications, maintains long term memory, and follows the user across all devices. This model introduces a tiered pricing structure that creates a scalable revenue engine while strengthening Microsoft’s long term dominance in productivity software. The proposal also introduces the concept of a dual AI verification system, in which Copilot performs tasks and a secondary model provides independent review. This structure increases reliability, reduces errors, and enhances user trust. Problem Statement The current Copilot experience is fragmented. Each application instance behaves as a separate assistant with limited continuity, limited memory, and limited cross application intelligence. Users must repeatedly re explain context, re establish preferences, and manually coordinate tasks across Word, Excel, PowerPoint, Outlook, and other Microsoft 365 applications. This fragmentation reduces efficiency, increases cognitive load, and prevents Copilot from functioning as a true personal assistant. It also limits Microsoft’s ability to monetize Copilot at scale, because the product does not yet offer a unified, persistent experience that users would be willing to subscribe to at higher tiers. Vision The vision is a single, persistent Copilot identity that the user logs into, similar to any modern online service. This identity follows the user across all devices and applications, retaining memory, preferences, formatting rules, workflows, and ongoing projects. In this model, Copilot becomes the central intelligence that operates the Microsoft Office ecosystem. Office applications become the tools, and Copilot becomes the operator. This transformation elevates Copilot from a chatbot to a long term digital assistant that remains with the user for decades. Functional Overview 1. Persistent Copilot Identity A single Copilot account that retains: Long term memory User preferences Formatting rules Writing style Project context Cross application workflows Templates and document structures This identity behaves like any other modern login system, such as Amazon, Walmart, or email services. 2. Copilot as the Central Intelligence of Office Copilot should be capable of: Opening and managing Word documents Applying templates and formatting Building PowerPoint presentations Managing Excel formulas and data structures Organizing files and directories Coordinating tasks across applications Executing workflows on behalf of the user Office becomes the body. Copilot becomes the brain. 3. Cross Device Continuity The user logs into Copilot once, and the assistant follows the user across: Desktop Laptop Mobile Web Cloud environments This creates a seamless, continuous experience. Tiered Pricing Model A tiered structure creates a scalable revenue engine and aligns with Microsoft’s existing subscription model. Tier 1: Free Copilot Basic chat No memory No continuity Limited functionality This tier serves as the entry point that encourages users to upgrade. Tier 2: Copilot with Memory and Formatting Persistent memory Document formatting intelligence Writing style retention Basic cross application awareness This tier provides immediate value and will attract a large user base. Tier 3: Cross Device Copilot Identity Full continuity across devices Unified assistant experience Project level intelligence Long term context retention This tier becomes the premium personal assistant model. Tier 4: Copilot as Full Office Manager Complete control of Word, Excel, PowerPoint, Outlook Workflow automation File management Multi application coordination Enterprise grade productivity This tier becomes the flagship offering for professionals and businesses. Optional Tier: Dual AI Verification (Copilot + Reviewer Model) Copilot performs tasks. A secondary model independently reviews output for: Accuracy Formatting Logic Consistency This reduces errors and increases trust. It becomes a high value premium tier. Competitive Advantage This architecture provides Microsoft with several strategic advantages: A unified assistant that no competitor currently offers A multi tier revenue structure that scales with user needs A long term relationship between user and assistant Increased adoption of Microsoft 365 subscriptions Strong differentiation from competing AI products Reduced user churn due to persistent memory and continuity This model positions Microsoft as the leader in personal and professional AI assistance. Long Term Strategic Value A persistent Copilot identity ensures that users remain within the Microsoft ecosystem for decades. As the assistant accumulates memory, preferences, and workflows, the cost of switching to another platform becomes extremely high. This creates: Long term subscription stability Increased enterprise adoption Stronger user loyalty A durable competitive moat Copilot becomes not only a feature, but a lifelong digital partner. Closing Statement I respectfully submit this proposal as a long time user who believes that Microsoft has the opportunity to define the future of personal and professional artificial intelligence. A unified Copilot identity, combined with a tiered pricing model and a dual AI verification system, will create a powerful, scalable, and enduring platform that strengthens Microsoft’s leadership in productivity software.
