Solution 1Recommended

Review the App's Connectors and Sharing Settings

Determine if the Power App uses premium features that exceed the standard entitlements of a Microsoft 365 E3 license.

Power Apps licensing is dictated by the specific connectors and capabilities the app utilizes. While a Microsoft 365 E3 license includes standard Power Apps use rights for Office 365 apps, it does not cover Premium, Custom, or On-Premises data connectors.

1
Identify Premium Connectors

Contact the app creator to check if the app utilizes Premium connectors (such as Microsoft Dataverse, SQL Server, or external APIs). If it does, a standalone Power Apps Per App or Per User plan is mandatory.

2
Check App Sharing Settings

Navigate to the Power Apps maker portal, select the app, and click 'Share' to ensure the specific user or their Office 365 group has been explicitly granted run permissions.

3
Verify Data Source Permissions

Ensure the user has not only been shared the app but also has direct access rights to the underlying data sources, such as the specific SharePoint site and lists the app queries.

Frequently Asked Questions

Does a Microsoft 365 E3 license include Power Apps?

Yes, Microsoft 365 E3 includes 'Power Apps for Office 365', which allows users to run custom apps that connect to standard services like SharePoint or Microsoft 365. However, this entitlement does not cover apps that use Premium connectors.

What does the 'additional-plan required' error mean in Power Apps?

This error typically occurs when a user attempts to launch an app that connects to a Premium data source (like Dataverse or SQL) or uses custom connectors. These require a standalone Power Apps license (Per App or Per User) rather than a standard Microsoft 365 E3 license.

How can I tell if a Power App uses Premium connectors?

The app maker or an administrator can view the app's details in the Power Apps Studio or Admin Center. Any premium connectors involved in the application will be marked with a small diamond icon next to their name.

Will having SharePoint list permissions bypass Power Apps licensing requirements?

No. While SharePoint list permissions allow a user to view the underlying data directly in SharePoint, accessing that data via a Power App strictly subjects the user to the licensing requirements of that specific app and all the connectors it utilizes.
