How Should Admins Prepare
June’s updates aren’t just feature releases, they introduce new dependencies between Copilot, data sources, and governance controls. Preparation isn’t optional if you want predictable outcomes.
1. Establish “Copilot-Ready” Data Sources
Copilot is now pulling from:
- SharePoint lists
- Meeting content (transcripts, chats, files)
- Authoritative SharePoint sites
What to do:
- Identify trusted data sources (HR, IT, policy, operations)
- Clean up:
- Permissions (remove oversharing)
- Naming conventions
- Data quality (structured lists especially)
- Designate Authoritative Sites early to control answer quality
Key insight: Copilot accuracy now depends more on your information architecture than Microsoft’s model
2. Re-Evaluate Your Security & Compliance Posture
Purview is tightening control over:
- Sensitivity labels (blocking AI-connected experiences)
- DLP precision and audit signals
- eDiscovery for Copilot and Loop content
What to do:
- Review sensitivity label policies:
- Decide which labels should block AI interactions
- Update DLP strategies:
- Leverage new conditions (e.g., labeled file count thresholds)
- Tune policies using richer audit data
- Expand eDiscovery scope:
- Include Copilot-generated and Loop-based content
Key insight: You’re moving from “protecting files” → to governing AI interactions with data
3. Define Agent Governance (Before Scaling)
With Work IQ + MCP + dynamic tool discovery:
- Agents can now call APIs
- Tools can update without redeployment
- Workflows can become autonomous
What to do:
- Establish:
- Who can create agents
- Who can publish tools
- How changes are approved and audited
- Treat agents like:
- Production apps
- With lifecycle management, logging, and ownership
Key insight: Agents are becoming your new automation layer—govern them like code
4. Pilot High-Impact Use Cases First
Don’t roll everything out broadly.
Start with:
- SharePoint list–based agents (structured data scenarios)
- Copilot Notebooks for project teams
- Teams event templates for standardization
What to do:
- Choose 1–2 departments (IT, operations, HR)
- Define clear success metrics (time saved, accuracy, adoption)
- Iterate based on real usage
Key insight: Copilot success comes from targeted enablement, not blanket rollout
5. Prepare Your Support & End Users
Several UX changes will hit users:
- Outlook (rules, layout, offline sync)
- Teams (events, downloads, previews)
- Copilot (history behavior, rewrite workflows)
What to do:
- Create a simple “What’s Changing” update
- Update:
- Help desk runbooks
- Training screenshots
- Equip support teams to answer:
- “Why did this stop working?” (labels/DLP impact)
- “Where did my Copilot chats go?”
Key insight: Small UX changes create disproportionate support tickets if ignored
6. Align Architecture to the New Reality
These updates reinforce a new Microsoft 365 model:
- Business Apps (Copilot, Agents, Teams)
- Endpoint & Experience (Outlook, Edge, Devices)
- Infrastructure & Governance (Purview, SharePoint, Identity)
What to do:
- Ensure your architecture reflects:
- Data → grounded → governed → surfaced via Copilot
- Map:
- Data sources → Copilot experiences → compliance controls
Key insight: This is no longer tool-by-tool—it’s a platform-level operating model
What’s Enabled by Default
How I interpreted “enabled by default” (important)
- Enabled by default (explicit) = the roadmap text literally states a default-on behavior (e.g., “opens by default”).
- Enabled by default (no admin enablement mentioned) = the roadmap text describes the capability as becoming available, without mentioning an admin toggle/policy/enablement step. This is likely default-on at rollout, but you should still validate in Message Center / admin portals because roadmap entries don’t always specify defaults. [June Roadmap
