Question details

The user needs to know if Outlook.com authentication tokens can refresh automatically in Power Automate after an account password has been changed.

Product: Power Automate / Outlook.com
Device & OS: not provided
Scenario: A Power Automate flow stops working and requires manual reauthentication due to a recent change in the Outlook.com account password.
Observed behavior: The Power Automate flow fails to execute and stops running because the connection to Outlook.com is broken by the invalid password.

Before you start

Ensure you have your newly updated Outlook.com password ready and can access your Microsoft Power Automate environment with sufficient permissions to edit connections.

Solution 1Recommended

Manually Re-authenticate the Outlook.com Connector

The quickest and most reliable way to restore your flows after a password change is to manually update the connection credentials in Power Automate.

Because password changes invalidate active authentication tokens for security reasons, Power Automate cannot automatically fetch a new token without your input. Manual reauthentication is required to restore service.

Access Power Automate

Navigate to the Power Automate web portal and sign in with your Microsoft account.

Go to Data Connections

On the left navigation menu, expand the 'Data' tab and select 'Connections'.

Locate the Broken Connection

Find your Outlook.com connection in the list. It will likely display an error status or a prompt that says 'Fix connection'.

Update Credentials

Click on 'Fix connection', enter your new Outlook.com password in the authentication popup, and approve the sign-in request to restore your flows.

Flows Resume Automatically: Once the connection status shows as 'Connected', any flows relying on this connector will be able to run successfully again.

Solution 2

Consult the Microsoft Power Platform Community

For advanced token lifecycle troubleshooting or questions about avoiding manual authentication, consult specialized Microsoft support resources.

Frequently Asked Questions

Why does my Power Automate flow fail after I change my Outlook password?

When you change your account password, the existing OAuth authentication token used by Power Automate becomes invalid for security reasons, immediately breaking the connection to Outlook.com.

Can Power Automate automatically refresh the password for Outlook.com?

No. Standard security protocols require you to manually re-authenticate your connection in Power Automate whenever the underlying account password is changed.

How do I know which flows are affected by a broken connection?

You can check the 'Connections' tab under 'Data' in the Power Automate portal. Connections that require authentication will show a 'Fix connection' warning, indicating that any flows relying on them are currently paused or failing.

Will my flows automatically restart after I fix the connection?

Yes, once you provide the new password and fix the connection, subsequent triggers will process normally. However, flow runs that failed during the downtime may need to be manually resubmitted.
