Question details
The user is unable to connect Power Automate actions within Copilot Studio due to invalid connection references preventing flow submission.

- Product
- Copilot Studio
- Device & OS
- not provided
- Scenario
- Attempting to execute or submit a Power Automate flow integrated with Copilot Studio.
- Observed behavior
- The connection fails, typically displaying an unexpected connection name or suffix (such as shared_office365_1) in the action reference.
Ensure you have proper editing permissions for the Power Automate flow and verify that your Microsoft 365 login credentials are up to date.
Re-add Connector Actions and Update Connection References
Resolve connection issues by deleting the faulty connector action and re-adding it with the correct connection reference.
When a flow uses an outdated or incorrect connection reference, Copilot Studio will fail to authenticate the Power Automate action. By clearing out the affected action and re-establishing it, you force the system to generate a fresh, valid authentication token.
Open the affected flow in Copilot Studio and navigate to the action's code view to inspect the backend parameters.
Check the connectionName parameter. Look for an unexpected suffix, such as 'shared_office365_1', which indicates an invalid or outdated connection reference.
If the reference is incorrect, click on the specific connector actions within the flow builder and delete them entirely.
Click the 'Save' button, close the flow editor completely, and then reopen the flow to refresh the session.
Click 'Add an action' to insert the previously deleted connector actions back into your flow, ensuring you select the correct and intended connection from the dropdown menu.

Frequently Asked Questions
Why does my Power Automate connection name have a 'shared_office365_1' suffix?
This typically happens when a flow is exported, imported, or duplicated. The system generates a new connection reference which sometimes becomes invalid or decoupled from your original authorized credentials.
Can I edit the connectionName directly in the Copilot Studio code view?
While you can view the connectionName in the code view, it is highly recommended to delete and re-add the action via the visual interface. Manual code edits can fail to generate the necessary backend authentication tokens.
Where can I find advanced support for Copilot Studio and Power Automate errors?
For highly technical issues involving flow integrations, the Microsoft Power Platform Community Forum is the best resource. You can share specific logs and error codes to receive help from specialized experts.
