Verify User Fields and Connector Configurations
Check the form's user fields and the related Power Automate flow to ensure the referenced account is valid and correctly configured.
This error typically occurs when the app or flow tries to look up an email address or user profile that does not exist, is misspelled, or is disconnected in Azure Active Directory.
Open your app in Power Apps Studio and select the form triggering the error. Verify that any 'Person' or 'User' fields are mapped to a valid, active email address.
Navigate to the Power Automate flow connected to your leave request. Ensure the 'Assigned to' field contains a valid user account within your organization's directory.
Go to the 'Data' pane in Power Apps, locate the 'Office 365 Users' connector, and refresh it to ensure there are no authentication issues or broken connections.

Consult the Power Apps Community
If verifying the user fields does not resolve the issue, seeking specialized help from the official community is the best next step.

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.
