🔴 Copilot Chat — April 15, 2026 Licensing Changes¶
Last updated: 2026-04-14 · Status: 🟢 Complete · Task: L36
⏰ Takes Effect April 15, 2026
These changes are 6 days away. If you work with Microsoft 365 customers, you need to know this cold.
📖 TL;DR¶
Starting April 15, 2026, Microsoft is removing or degrading free Copilot Chat inside Word, Excel, PowerPoint, and OneNote for users without a paid M365 Copilot license. The impact depends on your tenant size. This is a reversal of the September 2025 decision to give all M365 users in-app Copilot access.
🆕 April 14 Update — Gradual Rollout Expected
The change may not apply to all tenants on April 15. Based on Microsoft's standard MC rollout practices, changes take effect based on when each tenant received the notification. Also: "Standard vs Priority Access" is the official model per MC1253863 — paid users get Priority, free users get Standard (may be throttled).
⚠️ Internal insight — do not share publicly. From internal Supportability wiki + Field Enablement (April 14):
- The change may occur 30 days after MC communication was received by each tenant — creating a per-tenant rollout window, not a hard global switch-off on April 15.
- Priority Access (paid M365 Copilot) vs Standard Access (Chat users) is now the official behaviour model. Standard Access may include: feature throttling, queue-based reasoning workloads, and in-product upgrade prompts.
- Engineering + Field messaging explicitly frames: Copilot Chat = secure AI chat, M365 Copilot = full orchestration across apps, data, and agents. This is deliberate product line separation ahead of Agent-first roadmap.
- For NZ enterprise customers (MBIE, AUT, MPI etc.): expect questions about loss of in-app Copilot in WXPO, why Outlook still works, why SMB tenants appear unchanged.
📅 Timeline — How We Got Here¶
| Date | What Happened |
|---|---|
| Sep 2025 | Microsoft announced Copilot Chat available in Word, Excel, PPT, OneNote, Outlook for all M365 users — even without a paid Copilot license |
| Jan 2026 | Free users started getting Copilot side-panel in Office apps — positioned as "AI assistance where users need it" |
| Mar 17, 2026 | Two Message Center posts published — MC1253858 (>2K users) and MC1253863 (<2K users) — announcing the rollback |
| Apr 15, 2026 | Changes take effect |
Why the 180?¶
- Only ~3% of M365 customers pay for Copilot — Microsoft's own number
- The "try free → get hooked → upgrade" strategy didn't work
- AI infrastructure costs are too high to sustain free in-app access at scale
- Microsoft is tightening the value gap between free and paid to drive license adoption
🏢 The Two-Tier System — Tenant Size Matters¶
This is the most important part. Microsoft sent two different messages to two different audiences, creating significant confusion:
Message Center Posts¶
| MC1253858 | MC1253863 | |
|---|---|---|
| Sent to | Tenants with >2,000 users | Tenants with <2,000 users |
| Action | Copilot removed from WXP + OneNote | Copilot stays but degraded to "standard access" |
| Date published | March 17, 2026 | March 17, 2026 |
| Effective date | April 15, 2026 | April 15, 2026 |
What Each Tenant Size Experiences¶
| Feature | >2,000 Users (Enterprise) | <2,000 Users (SMB) |
|---|---|---|
| Copilot in Word | ❌ Removed | ⚠️ Standard access |
| Copilot in Excel | ❌ Removed | ⚠️ Standard access |
| Copilot in PowerPoint | ❌ Removed | ⚠️ Standard access |
| Copilot in OneNote | ❌ Removed | ❌ Removed |
| Copilot in Outlook | ✅ Stays (inbox + calendar) | ✅ Stays |
| Copilot web app | ✅ Stays | ✅ Stays |
| Copilot in Teams | ✅ Stays | ✅ Stays |
| Upgrade prompts shown | N/A (feature gone) | ✅ Yes |
The 2,000 User Threshold
The 2,000 user number comes from the MC message targeting. Note that Microsoft 365 Business plans (capped at 300 users) vs Enterprise plans is a separate licensing boundary. Some sources reference 300 users as the cutoff — this reflects the plan type, while 2,000 reflects how MC messages were targeted.
⚠️ What Is "Standard Access"?¶
For tenants under 2,000 users, unlicensed users keep Copilot Chat in Word, Excel, and PowerPoint, but under "standard access" conditions.
Think of it like economy vs business class on a flight:
| Aspect | Standard Access (Free) | Premium (Licensed) |
|---|---|---|
| Feature available | ✅ Yes | ✅ Yes |
| Speed/quality guaranteed | ❌ No — varies by capacity | ✅ Yes — priority |
| Available during peak hours | ⚠️ May be degraded | ✅ Always |
| Advanced reasoning models | ❌ No | ✅ Yes |
| Upgrade prompts | ✅ Shown frequently | ❌ None |
In plain English: you can still use it, but it might be slow, limited, or unavailable when lots of people are using it. Licensed users always get served first.
🏷️ New Labels¶
Microsoft is introducing new labels so users can see which tier they're on:
| Tier | Label | What it means |
|---|---|---|
| Free (unlicensed) | Copilot Chat (Basic) | Web-grounded chat, no Work Graph |
| Paid ($30/mo Enterprise) | M365 Copilot (Premium) | Full experience, Work Graph, Claude, agents |
These labels will appear in the Copilot UI across all apps.
✅ What FREE Users (Copilot Chat Basic) Still Get¶
Even after April 15, free users retain access to:
| Feature | Where | Notes |
|---|---|---|
| AI chat (web-grounded) | Web app, Outlook, Teams | Not grounded in org data |
| Copilot in Outlook | Outlook desktop + web | Inbox + calendar awareness |
| Copilot in Teams | Teams app | General chat, not meeting summaries |
| Copilot Pages | Web app | Collaborative AI canvas |
| File upload & analysis | Web app | Upload docs for AI analysis |
| Image generation | Web app | Create images from prompts |
| Enterprise Data Protection | Everywhere | Data doesn't train models |
| Pay-as-you-go agents | Web app | Metered billing per use |
| Prompt-only agents | Chat | Agents that just answer questions |
🔒 What Requires a Paid Copilot License¶
| Feature | Requires |
|---|---|
| Enterprise data grounding (Work Graph — emails, files, Teams, SharePoint) | M365 Copilot license |
| Full in-app Copilot in Word, Excel, PPT, OneNote | M365 Copilot license |
| Researcher agent (deep web research) | M365 Copilot license |
| Claude model (Anthropic) | M365 Copilot license + admin approval |
| Execution-based WXP agents (agents that DO things in documents) | M365 Copilot license |
| Meeting summaries in Teams | M365 Copilot license |
| Advanced reasoning / multi-model selection | M365 Copilot license |
| Priority performance (not throttled) | M365 Copilot license |
| Copilot Cowork (autonomous multi-step tasks) | M365 Copilot license |
| Copilot Critique (AI self-review) | M365 Copilot license |
| Copilot Council (multi-model comparison) | M365 Copilot license |
💰 Pricing¶
| Plan | Tenant Size | Price | Commitment |
|---|---|---|---|
| M365 Copilot (Enterprise) | >300 users | $30/user/month | Annual |
| M365 Copilot Business | <300 users | $21/user/month | Annual |
Both are add-on licenses on top of an existing Microsoft 365 subscription (E3/E5, Business Basic/Standard/Premium, etc.).
Example cost: 50-person company × $21/user/month = $12,600/year on top of existing M365 costs.
🤖 WXP Agents — The Biggest Surprise¶
🔑 Key Discovery
WXP Agents (Word, Excel, PowerPoint agents) are powered EXCLUSIVELY by Anthropic Claude — not OpenAI GPT. This means enabling Anthropic at the tenant level doesn't just "add another model" — it unlocks an entire Copilot feature set.
What Are WXP Agents?¶
WXP Agents are AI-driven creation agents that live inside the Microsoft 365 Copilot app. They can create entire Word documents, Excel workbooks, and PowerPoint presentations from a single prompt — with multi-step reasoning, iteration, and refinement.
Source: Microsoft Learn — WXP Agents
Which Model Powers Them?¶
| Copilot Feature | Model Used |
|---|---|
| Copilot Chat (general) | OpenAI GPT and Anthropic Claude (multi-model) |
| Researcher Agent | GPT or Claude (admin choice) |
| Copilot Studio Agents | GPT or Claude (admin choice) |
| WXP Agents (Word/Excel/PPT) | 🟠 Claude ONLY |
From the official Microsoft Learn docs:
"These agents exclusively use Anthropic's AI models. This AI model must be enabled. These requirements are mandatory for Word, Excel, and PowerPoint Agents to function."
This is NOT multi-model. WXP Agents are Claude-only today.
Anthropic ON/OFF = WXP Agents ON/OFF¶
| Anthropic Setting | WXP Agents Visible? | WXP Agents Work? |
|---|---|---|
| ✅ Enabled | ✅ Yes — appear in Tools menu + All Agents | ✅ Yes |
| ❌ Disabled | ❌ Completely hidden from all users | ❌ No |
From the docs:
"If administrators disable the Anthropic AI models, users are prevented from seeing the agents (in the Tools menu and in the left agent navigation pane) and using the new Word, Excel, and PowerPoint Agents."
🔥 WXP Agents ARE Available for Copilot Chat Basic (Unlicensed) Users!¶
This is the part that surprises people. From the official docs:
"Word, Excel, and PowerPoint Agents are installed by Microsoft and will appear… for Microsoft 365 users who are both Copilot chat users (unlicensed Copilot users) and Microsoft 365 Copilot users (licensed Copilot users) assuming Anthropic has been enabled for the tenant."
And further confirmed:
"Word, Excel, and PowerPoint Agents are available to Microsoft 365 users with or without a Microsoft 365 Copilot license."
⚠️ Critical Distinction: "Copilot in Word" vs "Word Agent in Copilot"¶
This is where everyone gets confused — including Microsoft field staff:
"Copilot IN Word" ≠ "Word Agent IN the Copilot App"
↓ ↓
Side panel inside Word Agent you talk to in Copilot app
(embedded in the app) (creates a Word doc for you)
↓ ↓
THIS gets removed/degraded THIS stays for everyone
- Copilot in Word = the side panel / Copilot button inside the Word application itself
- Word Agent = an agent you talk to in the Microsoft 365 Copilot app (m365.cloud.microsoft/chat) that creates an entire Word document for you
The April 15 changes remove the in-app experience. The agents in the Copilot app stay.
WXP Agents: Available for BOTH Tenant Sizes¶
| Copilot IN the apps (side panel) | WXP Agents in the Copilot App | |
|---|---|---|
| >2K tenants (unlicensed) | ❌ Removed April 15 | ✅ Still available |
| <2K tenants (unlicensed) | ⚠️ Standard access (throttled) | ✅ Still available |
| Both (Anthropic OFF) | N/A | ❌ Hidden for everyone |
Internal Microsoft guidance confirms:
"Taking away Copilot in WXPN apps, but now offering WXP agents in the M365 Copilot app."
Source: Internal ADO wiki + Teams thread (via WorkIQ)
So for a >2,000 user tenant unlicensed user after April 15:
- ❌ Can't open Word and use the Copilot side panel anymore
- ✅ Can open the Copilot app → talk to the Word Agent → get a full document created → saved to OneDrive
Full Comparison: Licensed vs Unlicensed After April 15¶
| Capability | Licensed (Premium) | Unlicensed (Basic) |
|---|---|---|
| Copilot side panel inside Word/Excel/PPT | ✅ | ❌ (>2K) / ⚠️ (<2K) |
| WXP Agents in Copilot app | ✅ | ✅ (if Anthropic ON) |
| Create docs from prompt via agent | ✅ | ✅ |
| Web-grounded content | ✅ | ✅ |
| File upload/attachment | ✅ | ✅ (limited) |
| Org data via Work Graph (emails, files, meetings, SharePoint) | ✅ | ❌ |
| Sensitivity labels respected | ✅ | N/A |
| Output saved to OneDrive | ✅ | ✅ |
Why This Causes Confusion¶
Copilot overall = multi-model (GPT + Claude) ✅
But...
WXP Agents = Claude-ONLY dependency ⚠️
So enabling Anthropic ≠ "adding another model option"
enabling Anthropic = unlocking WXP Agents entirely
This is why:
- NZ/AU public sector tenants often see no WXP agents at all — because Anthropic is OFF by default in regulated environments
- Some customers think WXP agents are "broken" when actually Anthropic just hasn't been enabled
- Customers who turn Anthropic OFF for compliance reasons lose WXP agents as a side effect
- People confuse "Copilot removed from Word" with "Word Agent removed" — they are different things!
🔜 Future: GPT-Based WXP Agents Coming¶
Internal Microsoft communications confirm:
"We are actively developing a GPT-based version of these Agents."
This means WXP agents will eventually work without the Anthropic dependency — but that is not the case today.
Customer-Ready Summary¶
What to tell customers
Word, Excel, and PowerPoint agents in Microsoft 365 Copilot currently rely exclusively on Anthropic Claude models. These agents are only available when Anthropic is enabled at the tenant level. If enabled, the agents appear for both licensed AND unlicensed users — but unlicensed users only get web-grounded content, while licensed users also get org data grounding. If Anthropic is disabled, the WXP agents disappear completely for everyone.
🧠 Anthropic Claude — Enablement Conditions¶
Claude is NOT available to free Copilot Chat users. Period.
Requirements to Use Claude in M365 Copilot¶
| Requirement | Details |
|---|---|
| M365 Copilot license | Paid license required |
| Admin approval | Global Admin enables in M365 Admin Center |
| Path | Admin Center → Copilot → Settings → Data access → AI providers |
Default State by Region¶
| Region | Default State | Action Required |
|---|---|---|
| Commercial (non-EU) | ✅ ON by default (since Jan 7, 2026) | Opt OUT if you don't want it |
| EU/EFTA/UK | ❌ OFF by default | Opt IN if you want it |
| GCC / GCC High / DoD | ❌ Not available | No toggle exists |
Key Details¶
- Where Claude appears: Researcher agent, Copilot Critique, Copilot Council
- Data protection: Covered by Microsoft DPA, BUT excluded from EU Data Boundary
- Session behaviour: Reverts to default GPT model when session ends
- New April 2026: Granular user/group assignment (up to 999 groups/users)
- Copilot Studio: Enabling Anthropic at tenant level cascades to Copilot Studio + Power Platform
⚠️ Critical for Customer Conversations
If an admin does nothing in a non-EU commercial tenant, Anthropic is already ON. Some customers may not realise their data is flowing to Claude. This is a governance conversation you need to raise proactively — especially with regulated industries (financial services, healthcare, government).

🎯 Customer FAQ¶
"Why can't I use Copilot in Word anymore?"¶
Starting April 15, 2026, Microsoft reserved in-app Copilot in Word, Excel, PowerPoint, and OneNote for paid M365 Copilot license holders. You can still use Copilot Chat via the web app at m365.cloud.microsoft/chat, in Outlook, and in Teams.
"We're a small company — are we affected?"¶
If your tenant has fewer than 2,000 Microsoft 365 users, you keep Copilot Chat in Word, Excel, and PowerPoint, but it runs under "standard access" — meaning performance may vary and you'll see upgrade prompts. OneNote access is removed regardless of size.
"Is Claude sending our data to Anthropic?"¶
If your admin hasn't explicitly disabled Anthropic as a subprocessor (and you're not in the EU), then yes — Claude is enabled by default since January 2026. Data is covered by Microsoft's DPA and Enterprise Data Protection, but it's excluded from the EU Data Boundary. Check with your admin in the M365 Admin Center → Copilot → Settings → Data access.
"Should we buy Copilot licenses?"¶
Evaluate based on actual usage. Key questions: (1) Do your users actively use Copilot today? (2) Do they need Work Graph grounding (searching emails, files)? (3) Do they use agents that manipulate documents? If yes to any, the paid license delivers measurably more value. If usage has been lukewarm, consider licensing only power users rather than the entire org.
"What's the cheapest option?"¶
For businesses under 300 users: $21/user/month (M365 Copilot Business). For enterprises: $30/user/month. You don't have to license everyone — consider starting with a pilot group of power users.
📋 Admin Actions Required¶
Before April 15¶
- [ ] Check your tenant size and identify which MC message applies to you
- [ ] Review Copilot usage data in M365 Admin Center → Usage reports
- [ ] Communicate changes to end users before April 15
- [ ] Decide: buy licenses for key users, or accept the downgrade?
- [ ] Review Anthropic subprocessor setting (is Claude enabled without your knowledge?)
Where to Check¶
| Setting | Location |
|---|---|
| MC messages | M365 Admin Center → Message Center → Search "MC1253858" or "MC1253863" |
| Copilot usage | M365 Admin Center → Reports → Usage |
| Anthropic toggle | M365 Admin Center → Copilot → Settings → Data access |
| Pin/unpin Copilot | M365 Admin Center → Copilot Control System → Settings |
