If you’re running Power Platform in your organization, this week brought a tsunami of updates that will change how you work. I’ve combed through the Message Center so you don’t have to. Here’s what matters.
Let's explore
🚨 Action Required: Tenant Isolation Goes Live February 1st
MC1221422 | This isn’t a drill. Starting February 1, 2026, Power Platform will block ALL cross-tenant connections by default. Part of Microsoft’s Secure Future Initiative, this affects any connector running between tenants.
What breaks: Connections from one tenant to another—inbound, outbound, or both—will be blocked. Same-tenant communications and guest user access remain unaffected.
Fix it now: Set up tenant isolation policies and explicitly allow individual tenants before February 1st. Or disable tenant isolation entirely. If you do nothing, your cross-tenant flows stop working.

🔥 Power Automate Gets Three Developer-Friendly Upgrades
Environment Variables in Desktop Flows
MC1226018 | GA: February 28, 2026
Stop passing environment variables as inputs. Desktop flows can now retrieve Power Platform Environment variables directly. Less manual work, fewer errors.
Inline Property Values in Cloud Flow Designer
MC1218891 | GA: February 10, 2026
Debug multiple steps at once. The new cloud flow designer shows property values expanded inline. No more clicking through each step to find what broke.
Debug Condition Actions Like a Pro
MC1218294 | GA: Already live since December 31, 2025
Condition actions now display runtime values for dynamic content and expressions. Track exactly which part of your complex logic failed.
🎯 Power Platform Admin Center: Your New Control Room
Power Platform Inventory is Now GA
MC1223778 | Status: Generally Available
See everything in one place. Agents, apps, flows, environments, environment groups—all in the unified Inventory page. Coming February 9th: environment groups support and the Power Platform for Admins V2 connector.
Access inventory data through the connector, API, or Azure Resource Graph.

New Usage Experience in Public Preview
MC1220728 | Rolling out: January 20 – February 2, 2026
Track adoption trends, identify top-used resources, and make data-driven decisions. Admins finally get clear visibility into what’s actually being used.
Environments Page Updates
MC1226444 | Effective: February 3, 2026
The Manage option and release wave label disappear from the Updates card. A new link directs you to Release Channel settings. Your environment behavior now depends on Release Channel configuration.
Copilot Adoption Tracking Gets Better
MC1218332 | GA: January 16, 2026
Click any agent in the Copilot Studio page and see: 30-day usage, activity success rates with visual breakdowns, and monthly trend charts. Jump directly to the Manage hub by clicking the environment name.
🤖 Copilot Studio: Smarter Agents, Better Controls
Dynamic Filtering for Knowledge Sources
MC1223795 | GA: February 28, 2026
Filter which knowledge sources your agents can access. Streamline workflows and make responses more relevant by controlling what data agents tap into.
Draft with Copilot
MC1165633 | GA: February 28, 2026
Let Copilot write your prompts. Turn rough ideas into effective prompts that follow best practices. It even generates sample test data for faster validation.
Content Moderation Settings
MC1217615 | GA: January 31, 2026
Adjust moderation levels for AI prompts in the settings panel. Lower moderation = higher risk but more responses. Higher moderation = safer but potentially fewer responses. You choose the balance.
Copilot Studio Product Terms Update
MC1225193 | Effective: Early February 2026
New commitments for how Query Data from Entra ID-authenticated Copilot Studio is handled when sent to Bing Search:
- Query Data isn’t used to improve Bing
- Not used for advertising profiles or tracking
- Not shared with advertisers
- Not used to train AI models
- Treated as confidential with technical controls
No changes to user experience or settings. Review with your privacy and legal teams if needed.
💻 Power Apps & Power Pages Updates
Content Security Policy Enforcement for Code Apps
MC1218747 | Enforcement: January 30, 2026
Strict CSP enforcement starts January 26th. After January 30th, code apps calling external assets will have requests blocked by default. Your app plays, but external assets won’t load.
Fix it: Allowlist required external sources in Power Platform admin center. If unsure what to allowlist:
- Toggle off “Enforce content security policy”
- Toggle on “Enable reporting”
- Test and identify required sources after January 30th
- Add sources to allowlist
- Toggle enforcement back on
Power Pages Client APIs
MC1224376 | GA: February 28, 2026
Control components without fragile DOM manipulation. New JavaScript APIs let you manage forms, lists, user authentication, and web data. Hide fields, update values, trigger actions—all without custom JavaScript hacks.
Key features: Form API, List API, User API, Web API with OData methods.
📊 Power BI: Two Major Retirements Coming
Q&A Feature Retirement
MC1218421 | Retirement: December 2026
Power BI Q&A—the legacy natural language tool—is done. After December 2026, Q&A visuals in reports, dashboards, mobile, and embedded scenarios stop working. Q&A Setup tools (synonyms, linguistic relationships) also retire.
Migration path: Transition to Power BI Copilot for natural language queries. Review reports now and plan replacements.
On-Prem SharePoint Web Part Support Ends
MC1217651 | End of support: April 13, 2026
The SSRS Report Viewer SharePoint Webpart loses support. You can still download and use it, but no updates or support after April 13th. The feature stays functional but unsupported.
Alternative: Embed SSRS reports in SharePoint using URL parameters.

Copilot Capacity Designation Enabled by Default
MC1217152 | Rollout: On or after February 12, 2026
The tenant setting “Capacities can be designated as Fabric Copilot capacities” turns on by default for all tenants. This changes the setting, not your existing capacity configuration.
If capacities aren’t enabled for Fabric Copilot, nothing changes for you. Want to opt out? Turn the setting on in the Fabric admin portal, then immediately turn it off before rollout.
✅ Bottom Line
The Power Platform team shipped 17 updates this week. Most are awareness-only. But tenant isolation on February 1st and CSP enforcement on January 30th require action if you have cross-tenant connections or Power Apps code apps calling external assets.
Everything else? Features that make your life easier—better debugging, cleaner admin experiences, smarter Copilot controls, and a clear migration path away from legacy tools.
Block 30 minutes this week. Review your tenant isolation policy and CSP settings. Then explore the new inventory and usage pages in PPAC. Your future self will thank you.
