To work with the Power BI service, you need an organizational email ID. While Power BI does not specifically restrict the use of Hotmail or personal accounts for licensing or subscription purposes, there may be limitations or issues when using Hotmail accounts with Azure subscriptions, which can indirectly affect Power BI access.
Power BI restricts the use of email addresses from consumer email services or telecommunications providers for sign-ups. To complete the signup process, you must use an email address provided by your work or school. This requirement ensures security and compliance with organizational policies.
