In addition to the standalone Copilot Chat app, users with a commercial Microsoft 365 plan can currently access Copilot from inside apps such as Word, Excel, PowerPoint, and Outlook. As of April 15, 2026, however, Microsoft will remove access to Copilot from within the M365 apps in organizations with more than 2,000 users, unless those organizations pay for the M365 Copilot add-on license. Enterprises with fewer than 2,000 users will still be able to access Copilot from the M365 apps but will be subject usage limits. Copilot access will continue in Outlook but no other M365 apps.
To help users distinguish between the two versions, Microsoft is introducing two in-product labels: “Copilot Chat (Basic)” if they don’t have a Microsoft 365 Copilot license and “M365 Copilot (Premium)” if they do.
There are other Copilot add-ons as well, including Security Copilot and Copilot Studio, a low-code tool for building AI agents. Both offer usage-based pricing.
Microsoft Power Apps offers three primary pricing tiers tailored to different organizational needs. The Developer Plan is free for building and testing apps in a dedicated environment. For production use, Microsoft offers the Premium Plan. The first version costs $20/user/month (billed annually), allowing users to run unlimited applications. Organizations with large-scale deployments can access a discounted rate of $12/user/month with a 2,000-seat minimum.
All paid plans include access to the Dataverse, prebuilt connectors, and managed environments. Additional add-ons are available for Dataverse storage capacity ($40/GB) and Power Pages authenticated users.
There’s also a Teams add-on package, Teams Premium, which provides access to several features not included in the core app for an additional $10/user/month (currently on offer for $7/user/month). This includes live caption translations, custom branding in Teams meeting “lobbies,” AI-generated tasks and notes, end-to-end encryption for group calls, and more.
Microsoft has also introduced premium add-on packages branded as “suites.” Take Microsoft Viva, for instance, the set of employee experience applications that includes Viva Learning, Viva Engage, Viva Connections, Viva Glint, and more. While certain features of each Viva are available within most enterprise M365 subscriptions, others can be purchased individually (Viva Glint, for example) or via one of three Viva add-on bundle tiers. Viva Suite is the most comprehensive of these, with access to all the Viva features for an extra $12/user/month.
Entra Suite, a collection of identity and access tools, and Intune Suite for endpoint management and security are other examples of bundled add-ons available for additional monthly fees.
Tracking M365 sales
Microsoft still blends Microsoft 365 and Office 365 sales in its financial reports, so it’s difficult to track exact splits. However, the trajectory is clear: Microsoft is moving from productivity to AI-led operations.
Office 365 commercial seats have passed 450 million globally. While seat growth has slowed to single digits (5-6% year-over-year based on 2025 earnings), revenue growth remains in the double digits — thanks largely to Microsoft aggressively pushing toward E5 upgrades and upselling Microsoft 365 Copilot.
As a comparison, Google Workspace — M365’s primary rival — reported surpassing 12 million paying organizations in late 2025. While Google remains a viable alternative, Microsoft’s entrenched position in the enterprise benefits from the October 2025 end-of-support for Windows 10. This has forced a massive hardware refresh cycle, pushing Windows 11 adoption past the 55% mark and pushing more organizations to M365 E3/E5.
What’s new in M365?
The integration of Copilot across M365 apps has undoubtedly been the major focus for Microsoft in the past couple of years. It’s rare to see a product news update on the Microsoft 365 blog that doesn’t reference the AI assistant in some way.
Recent feature additions include a new Team Copilot that provides AI assistance in group meetings and makes suggestions for task management; Copilot Studio for customizing Copilots in M365; access to OpenAI’s GPT-4 Turbo model; and the general availability of Microsoft’s Designer AI image generator. Other new apps and features include Mesh immersive meetings for Teams, Places for hybrid work coordination, and a UI refresh for the Loop collaboration app.
According to Microsoft, the new Microsoft 365 E7 suite (announced in March) marks a shift toward the agent-operated enterprise. Launching May 1, 2026 for $99/user/month ($90.45 without Teams), E7 is designed to unify the M365 E5 offering with Microsoft 365 Copilot and the upcoming Agent 365. Also available as a standalone service priced at $15/user/month, Agent 365 essentially acts as the “control plane” for IT to see what your AI agents are actually doing.
