TL;DR: Copilot Chat is now natively embedded in M365 apps.
Outlook = free for all eligible users.
Word/Excel/PPT/OneNote = needs Copilot add-on license.
Enterprise data protection = built in.
Deploy = 3 steps via M365 Admin Center.
What Changed
Microsoft shipped Copilot Chat as a persistent AI panel inside Word, Excel, PowerPoint, OneNote and Outlook. It is native to the M365 desktop clients — not a browser extension, not a separate app.
Architecture and Security
Key points for IT admins:
- Prompts and responses are not used to train models
- Data stays within your M365 tenant boundary
- Uses Microsoft's Enterprise Data Protection (EDP) framework
- Admin control via M365 Admin Center + Cloud Policy service
- Web search can be enabled or disabled per policy
- Compatible with Conditional Access and DLP policies
Licensing Model
The Basic tier includes Outlook chat, web-grounded responses, file uploads, image generation, and Copilot Pages, and is included with eligible Microsoft 365 subscriptions. The Premium tier includes everything in the Basic tier, along with integration across Word, Excel, PowerPoint, and OneNote, plus enterprise data grounding, meeting summaries, and AI agents, available through an additional add-on license.
Deployment Steps
Step 1: Verify M365 plan eligibility
→ Business Standard, Business Premium, E3, E5
Step 2: Assign Copilot licenses
→ M365 Admin Center → Billing → Licenses
→ Assign Basic or Premium to target users
Step 3: Configure Copilot Control System
→ Set web search permissions
→ Define data access boundaries
→ Pin Copilot app for user groups
→ Configure Cloud Policy service settings
Recommended Rollout
Microsoft recommends a phased approach:
Phase 1 — Pilot group (20-50 users from IT, HR, Finance)
Phase 2 — User enablement training + feedback collection
Phase 3 — Governance configuration + policy enforcement
Phase 4 — Organisation-wide rollout
Pay-as-you-go Agents
Organisations can enable metered agents that perform multi-step tasks autonomously. Costs are usage-based. Useful for automating complex workflows like:
- Document processing pipelines
- Multi-step approval workflows
- Data extraction and reporting chains
Indian Enterprise Considerations
- DPDP Act compliance: Data stays within tenant boundary
- Data residency: Azure India regions available
- Licensing: Work with a Microsoft CSP partner for volume pricing in INR
