Power BI and Fabric Limiting User Levels: Consolidate Now 

• Microsoft is limiting the number of individual assignments in Power BI and Fabric workspaces.
• Administrators need to move user assignments into Entra ID groups to avoid the limits.

Microsoft is limiting Power BI and Fabric workspace role assignments to no more than 1,000 individual users and groups beginning Aug. 2025. The new limit is likely to impact only long-time customers who have added individual users to workspaces over several years or who have automated processes for adding new employees to certain workspaces during onboarding. Microsoft cites improved performance and reliability as the rationale for the limit, which affects all workspace roles (Admin, Member, Contributor, and Viewer).  

Leveraging Entra ID Groups  

The new limit will encourage customers to make better use of Entra ID groups, rather than individual users, for granting access. An Entra ID group, regardless of how many individuals are in it, counts as only one of the available 1,000 slots. For example, viewers of an organization’s safety metrics workspace, which could be the entire organization, can all be placed in one Entra ID group that is given a workspace Viewer role.
