Fix Power Automate Forms Connection Invalid When Activating Flow
Question details
The user is unable to activate a flow in Power Automate because the associated Microsoft Forms connection is flagged as invalid or inaccessible.
- Product
- Microsoft Power Automate
- Device & OS
- not provided
- Scenario
- Activating an automated flow that relies on Microsoft Forms as a trigger or action.
- Observed behavior
- Power Automate blocks flow activation and displays an error stating the Microsoft Forms connection cannot be used due to being invalid, prompting the user to replace it or contact the connection owner.
Verify that your Microsoft account password has not recently expired and that you have the necessary administrative permissions to edit the affected Microsoft Forms and Power Automate flow.
Recreate the Microsoft Forms Connection
Replacing the broken connection refreshes your authentication tokens and resolves most invalid connection errors.
Authentication tokens for external services like Microsoft Forms can expire or become corrupted due to password changes or security policy updates. Deleting and recreating the connection ensures Power Automate has the correct access rights.
Log into Power Automate, expand the 'Data' menu on the left sidebar, and click on 'Connections'.
Locate the Microsoft Forms connection in the list, click the ellipsis (...) next to it, and select 'Delete'.
Click 'New connection' at the top of the page, search for Microsoft Forms, and sign in with your active Microsoft 365 credentials.
Open your broken flow in edit mode, select the Microsoft Forms trigger or action, and assign the newly created connection before saving and testing the flow.
Consult the Power Platform Community
If recreating the connection fails, the issue may be a known bug requiring assistance from specialized Microsoft engineers.

Frequently Asked Questions
Why did my Microsoft Forms connection suddenly become invalid?
Connections typically break when the user's password expires, Multi-Factor Authentication (MFA) settings are modified, or organizational IT policies revoke the app's permissions.
How do I fix the error if I am not the owner of the connection?
You must contact the user who originally created the connection and ask them to either repair the connection in their account or share the flow so you can replace their connection with your own.
Does WPS Office offer alternatives to Microsoft Forms?
Yes, WPS Office includes robust PDF editing capabilities that allow you to create interactive, fillable PDF forms, which can be easily distributed and collected without requiring complex cloud automations.
Can I transfer ownership of a flow if the original creator leaves the company?
Yes, a Microsoft 365 global admin or Power Platform admin can reassign ownership of the flow to an active user via the Power Platform admin center.
