Hi kricy gundarania,
Thank you for reaching out to us on Microsoft Q&A forum.
No, you cannot buy a Power BI Pro license with a personal email account. You need a Microsoft 365 or Azure AD account (work email) to purchase and use Power BI Pro.
Power BI doesn't specifically restrict the use of Hotmail accounts for licensing or subscription purposes. However, there could be certain limitations or issues related to using Hotmail accounts with Azure subscriptions, which might indirectly affect Power BI access.
Power BI has some restrictions on using email addresses from consumer email services or telecommunications providers for sign-ups. "To complete the signup process, you'll need to use an email address provided by your work or school". This requirement ensures security and compliance with organizational policies.
