How can I hide my email contact in RLS message?

Hi , Anonymous 

According to your description, you configure RLS to your dataset and when a people have not configure the roles in dataset , they will get the access denied message.

According to my research and search, I have not found a place to set this prompt information in Powerbi, which should be returned directly by the front end.

You can submit your ideas to Power BI Idea to improve this product.

Secondly, for your needs, you can configure these roles without permissions into Security, and set a permission that cannot see the data, so that users will not report errors when they come in, but they cannot see the data.

Or, you can take over dataset owner and switch to another account for management, and your account information will not be displayed here.

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

Best Regards,

Aniya Zhang
