Azure Active Directory Errors

Resolution 1: Enable storage of local data in your browser


PowerApps Web Authoring stores some data locally in your browser, including user identity and preferences. PowerApps Web Authoring can’t function if the browser is configured to disallow this.

Resolution 2: Configure Trust Zones for Internet Explorer and Edge


Internet Explorer and Edge use Trust Zones. Problems can occur if services on which PowerApps Web Authoring relies are in different Trust Zones in your browser settings. While these settings apply to both Internet Explorer and Edge, the easiest way to access them is from Internet Explorer. (You might need assistance from your IT administrator to change some of these settings.)

Resolution 3: Azure Active Directory Errors


Azure Active Directory (AAD) is the technology on which the PowerApps ecosystem relies for user authentication and authorization.

The error page that you see might contain additional information that can help diagnose and fix the problem.

Note To resolve ADD errors, you might need assistance from your IT department.
