Scenario
Automating team email notifications for newly submitted event form responses.
Observed behavior
The flow saves successfully and indicates no errors, but the intended recipients do not receive the test notification emails.

Solution 1Recommended

Review Flow Run History and Connection Settings

Checking the run history helps isolate whether the issue lies with the form trigger failing to activate or the email action failing to send.

If a flow saves without errors but doesn't perform its task, the best diagnostic tool is the run history. It will show if the flow was triggered at all and where it stopped.

1
Check Run History

Navigate to 'My flows' in Power Automate, select your specific workflow, and click on '28-day run history'. Look for any failed runs or check if no runs were logged when you submitted a test response.

2
Verify Form ID

Click 'Edit' on your flow. Click on the trigger ('When a new response is submitted') and ensure the exact form you are testing is selected in the Form ID dropdown.

3
Check Connection Permissions

Navigate to the 'Data' > 'Connections' menu in the sidebar. Ensure that the connections for both Microsoft Forms and your email provider (e.g., Office 365 Outlook) say 'Connected' and do not require re-authentication.

Frequently Asked Questions

Why does my Power Automate run history show 'Succeeded' but no email arrived?

The flow executed successfully without software errors, but the email may have been caught in your organization's spam/quarantine filter. Alternatively, if your flow uses conditional branches, the logic might have evaluated to 'false', bypassing the email action entirely.

How do I know if my form trigger is working properly?

You can verify the trigger by checking the flow's 'Run history'. If you submit a new form response and no new entry appears in the run history within a few minutes, the trigger condition is failing, the flow is disabled, or the wrong Form ID is selected.

Do I need a premium license to send email notifications in Power Automate?

Sending standard notification emails via the Office 365 Outlook or Mail connectors is typically included in standard Microsoft 365 basic licenses. However, utilizing specific third-party connectors or enterprise mailing services may require a premium Power Automate license.
