Requirements: Admin role.
- Open Microsoft Dynamics 365’s Detail, go to the Status tab and click Disconnect.
- Confirm on the notice — the action can’t be undone.
Result: the saved credential is deleted, activated actions stop running immediately and the agent loses access to Dynamics’s tools. To connect again, repeat section 3 (a new client secret) and section 4. The app registered in your Entra ID and the application user in Power Platform still exist — you can reuse them.
Note — Dynamics becomes a destination for your own data
If you activate “Lead → contact” (section 5), the lead’s data travels to your own Dynamics 365 environment — a system that’s already yours, contracted and managed by you, not by your provider for this platform. Disconnecting stops the sync but doesn’t delete what was already synced to your Dynamics before, because that’s your system, not your provider’s. If you unsubscribed an end customer and they requested erasure, that erasure applies on the Platform; it doesn’t automatically delete what already travelled to your Dynamics.
