**Can I connect more than one Dynamics environment?** Not in this version: each tenant has a single Dynamics 365 connection at a time (the "principal" one, Connections tab). **"Test connection" says everything's fine, but a real action fails with "insufficient security role" — what do I do?** Go back to section 3, step 7: review the security role assigned to the application user in Power Platform admin center and confirm it has create/edit permissions on contacts and opportunities. "Test connection" only validates the credential, never that role. **The secret stopped working — what message will I see?** If the client secret is invalid or expired in Entra ID, both when connecting and on "Test connection" you'll see *"The token isn't valid; check it and try again"* (code `INTEGRATION_CREDENTIAL_INVALID`). Generate a new secret under **Certificates & secrets** (section 3) and repeat section 4. **Dynamics isn't responding — what message will I see?** If Microsoft has a one-off incident, you'll see *"The provider isn't available right now. Try again later"* (code `INTEGRATION_PROVIDER_UNAVAILABLE`) — it's not a problem with your credential, try again in a few minutes. **Can the agent delete contacts or opportunities in Dynamics?** No. The agent's tools (section 7) only search, create and update — they never delete anything in your Dynamics.
