Frequently Asked Questions

Why does the Leave Request approval flow fail with a user not found error?

This usually happens if the email address assigned to the approver field in Power Automate is misspelled, inactive, or belongs to a user who has been removed from your organization's Azure Active Directory.

How can I test if the Office 365 Users connector is the root cause?

Navigate to the 'Data' tab in your Power Apps Studio, find the 'Office 365 Users' connection, and re-authenticate. If it prompts for credentials or shows a warning icon, the connector needs to be repaired or recreated.

Can external guest users cause this Power Apps error?

Yes, if your app or flow attempts to look up an external guest user who has not been properly provisioned or invited to your organization's tenant, the system will not be able to resolve their account, resulting in this error.
