Microsoft tightens connector rules across Power Platform environments
Advanced Connector Policies became generally available on 4 June 2026. The new system replaces classic DLP policies with one policy per environment or environment group. Admins can now block entire connectors or individual actions inside them. The policy also covers MCP servers used by AI agents and applies at both design time and runtime. New environments inherit the policy automatically when they join an environment group. Makers see blocked connectors immediately while building.
Until now most makers in mid-size companies worked in environments where only the broadest DLP rules applied. They could add any connector that appeared in the list and test it without hitting an admin gate. The switch to Advanced Connector Policies moves that gate earlier. A connector that worked last month can disappear from the picker tomorrow if an admin adds it to the block list, and the maker will not know why until the flow fails to save.
Analysis
Assume your environment will soon enforce stricter rules than it does today. Open Power Automate, note every connector your active flows actually use, then ask the person who manages environments whether any of them are already restricted under the new policy.
