Microsoft has fundamentally overhauled the licensing architecture of its Copilot product family. Since April 15, 2026, a clear two-tier model applies: Copilot Chat (Basic) and M365 Copilot (Premium). The previous transition phase, during which users without additional licenses could use AI features directly in Office applications, has ended.
What's Changing: Withdrawal from Word, Excel and PowerPoint
The most significant change affects integration into core applications. Users without a paid Premium license lose access to Copilot directly in Word, Excel, PowerPoint and OneNote. The AI buttons in the ribbon of these programs are now exclusively reserved for paying customers.
Microsoft justifies this move with the high computational costs for deep document analysis and complex reasoning. For businesses, this means: anyone who regularly creates presentations, analyzes spreadsheets or generates lengthy texts will need a Premium license.
What Remains: Copilot Chat and Outlook
Basic functionality is preserved. The secure AI web chat remains available via the Microsoft 365 Copilot App – including web research, text drafts and general question-and-answer capabilities. Integration into Outlook (inbox and calendar) also remains available to all users.
This strategy reveals Microsoft's priorities: Copilot as a tool for information management and communication stays freely accessible. Creative work in documents is being monetized.
Five Variants, One Name
The confusion around the "Copilot" brand name remains a challenge. Fundamentally different products exist under the same label:
- Copilot Free (Personal): For home use – powerful but without Enterprise Data Protection. Business data has no place here.
- Copilot Chat (Commercial/Basic): Free for any employee with an M365 account. Secure environment, but no Office integration.
- Microsoft 365 Copilot Business: For SMBs up to 300 users. Full integration in Word, Excel, PowerPoint, Teams including access to internal company data via Microsoft Graph.
- Microsoft 365 Copilot Enterprise: For large enterprises with unlimited users and extended governance features.
- Copilot Studio: Not an AI assistant, but a workbench for building custom AI agents and workflows. The Copilot Studio Estimator helps calculate expected costs in advance.
AI Models: GPT and Claude Under One Roof
The multi-model strategy is noteworthy: since January 2026, Anthropic has been an official Microsoft sub-processor. Alongside OpenAI's GPT models, Claude models are also available in Copilot – at no additional cost. Depending on the task, Copilot automatically selects the appropriate model or offers users a choice.
Data Privacy as a Decision Factor
For IT leaders, data privacy remains the key differentiator. The personal Copilot version stores inputs and potentially uses them for AI training. All commercial variants offer Enterprise Data Protection: prompts are discarded, and no data flows into training models.
The recommendation is clear: employees should always sign in with their corporate ID in the browser to automatically enter the protected commercial variant.
Action Required for Businesses
The transition demands swift action. Organizations should now analyze which employees have actively used Copilot in Office apps – the Usage Reports in the Admin Center provide the data. This enables targeted decisions about who needs a Premium license and where the free Basic variant suffices.
The core question for every organization is: is the time savings from AI-powered document creation worth the monthly surcharge? The answer depends on the specific work profile – and should be made based on data.
