Power BI Reports & External Users

Hi  Pfin ,

Thanks for the nice reply from lbendlin .

Power BI enables sharing content with external guest users.This allows you to share content with external guest users that they can then access in their own home tenant. You need to enable the ‘Invite external users to your organization’ feature in the Power BI admin portal before inviting guest users. After an external user accepts the invite, they become a Microsoft Entra B2B guest user in your organization. Guest users only require invitations the first time you invite them to your organization. To invite users, use planned or ad hoc invites.

As for license,the guest user must have the proper licensing in place to view the content that you shared. There are a few ways to make sure the user has a proper license:

1.Use Power BI Premium capacity.
2.Assign a Power BI Pro or a Premium Per User (PPU) license.
3.Use a guest's Power BI Pro or PPU license.
