Hi Adilson Teixeira,
Thank you for reaching out to us on the Microsoft Q&A forum.
In the Power BI Service (app.powerbi.com), a work or school email address is required to sign up, as personal email addresses (like Gmail or Hotmail) are not accepted.
Here’s how you can proceed:
Use a work or school email: If you have access to one from your employer or educational institution, you can use that to sign in.
Create a Microsoft 365 account: If you don’t have a work or school email, you can sign up for a free Microsoft 365 trial https://www.microsoft.com/en-us/microsoft-365/try. This will provide you with an organizational email that you can use to access Power BI Service.
If you’re using Power BI Desktop, there’s no need for a work or school email—you can use the tool without signing in to the Power BI Service.
If you are still facing any issue, please let us know in the comments and where you are encountering this error along with the screenshot for reference. We are glad to help you.
