The “Unsupported Connector” error in Power Automate occurs when a connector is not supported for a specific action or data operation.
Error Message:
"Unsupported connector – The connector used in the flow is unsupported for the action or data."
This issue typically happens when:
- A premium connector is used without the required license.
- A deprecated or discontinued connector is used.
- The connector does not support the selected action.
- The connector is restricted by organizational policies.
2. Common Causes and Fixes
| Cause | Description | Fix |
|---|---|---|
| Premium Connector Without License | The connector requires a premium plan to use. | Upgrade to a Power Automate Premium or Per-User Plan. |
| Deprecated or Unsupported Connector | The connector is no longer available or discontinued. | Check Microsoft’s official connector list for alternatives. |
| Connector Not Available in Region | Some connectors are region-specific. | Use a different environment or region where the connector is supported. |
| Connector Does Not Support the Action | Not all actions are available in every connector. | Use a supported action or try a different connector. |
| Blocked by Data Loss Prevention (DLP) Policies | Organizational security policies block certain connectors. | Request an admin to allow the connector in DLP settings. |
| Connector in Preview/Beta | Some preview connectors are unstable or unsupported. | Use a stable version or check Microsoft’s support status. |
3. Step-by-Step Troubleshooting Guide
Step 1: Check if the Connector Requires a Premium License
Some connectors require a Power Automate Premium plan.
Steps to check:
- Open Power Automate.
- Navigate to Flow Details → Connections.
- Check if the connector is labeled Premium.
- If yes, upgrade to a Premium or Per-User Plan.
Example Fix:
- If you are using the SQL Server (Premium) connector, but have a free license, upgrade to a Power Automate Premium plan.
Step 2: Verify if the Connector is Deprecated or Unsupported
Microsoft periodically discontinues older connectors.
Steps to check:
- Visit the Microsoft Power Automate Connectors page.
- Search for the connector to see if it is still supported.
- If it’s deprecated, replace it with a newer connector.
Example Fix:
- If “Dynamics 365 (Legacy)” is no longer supported, switch to “Dataverse” instead.

Step 3: Check if the Connector Supports the Selected Action
Not all actions are available in every connector.
Steps to fix:
- Open Power Automate and go to Flow Designer.
- Click on the action causing the error.
- Check the available actions and triggers for that connector.
- If the action is unsupported, try a different one.
Example Fix:
- If “Get Rows” is not available in an Excel Online connector, use “List Rows Present in Table” instead.
Step 4: Ensure the Connector is Allowed by DLP Policies
Some organizations block certain connectors for security reasons.
Steps to check:
- Open Power Automate Admin Center.
- Navigate to Data Policies.
- Look for any blocked connectors in the DLP settings.
- If blocked, request an admin to allow it.
Example Fix:
- If your organization blocks Dropbox, request an admin to approve it in DLP settings.
Step 5: Use a Different Connector or Custom API
If the connector is unavailable, consider using:
- A similar supported connector.
- A custom connector to integrate the service manually.
Example Fix:
- If Google Drive is unsupported, use OneDrive or create a custom API integration.
