Premium Workspace Access

Hi , Anonymous 

Regarding your specific question, if you only add some users to the view permissions of this workspace through Azure AD groups, but do not add any other members, but users who are not included in this Azure AD group can access the reports in the workspace, my judgment on this situation is that these users have been added to the access rights of this report at other levels (such as report level, app level, dataset level, or share directly through link), If it is convenient for you, you can directly open the "Manage permission" option of this report to view the permission management of this report, check what the user is granted, and then delete them:

For how to share various Power BI reports, you can check this official document:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

Best Regards,
