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.)

Option 1: Add the required PowerApps domains to the Trusted Sites zone

On the browser toolbar, select the gear icon [Asset 4023948].
Select Internet Options.
Select the Security tab.
Select Trusted sites.
Select Sites.
Add the following sites by typing the address and selecting Add for each:

https://login.microsoftonline.com
https://create.powerapps.com
https://*.create.powerapps.com (the asterisk is part of the address, don't replace it)
https://*.powerapps.com (the asterisk is part of the address, don't replace it)

Select Close.
Select OK.
Close all Internet Explorer and Edge windows.

Option 2: Remove all the PowerApps domains from the Trusted Sites zone

On the browser toolbar, select the gear icon [Asset 4023948].
Select Internet Options.
Select the Security tab.
Select Trusted sites.
Select Sites.
Remove all existing entries for the following sites:

https://login.microsoftonline.com
https://create.powerapps.com
https://*.create.powerapps.com
Any other address that ends in powerapps.com or create.powerapps.com.

Select Close.

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.
