    Hi Amol Kshirsagar

    Thank you for reaching out to Microsoft Q&A forum

    You can refer to the Q&A assist answer above for the reason for this error. As stated in the document, the onmicrosoft.com account is not supported for logging in as a developer tenant.

    Additionally, I would like to provide information about the recently updated eligibility requirements for the E5 development program. At present, immediate sandbox provisioning is primarily offered to users with an active Visual Studio Professional or Enterprise subscription. These requirements are detailed in the Microsoft 365 Developer Program FAQ.

    It seems that you are trying to sign in with an account that uses the *.onmicrosoft.com domain, which is not supported for signing up or signing in to the Microsoft 365 Developer Program. You will need to use a different email account that is not associated with the *.onmicrosoft.com domain.

    Please ensure that you are using a valid work account, Visual Studio ID, or a personal Microsoft account for the sign-in process. If you continue to experience issues, you may want to check the Microsoft 365 Developer Program FAQ for further assistance.
