To log in to Azure as a student, you need to create a Microsoft account using your university email address. Since you mentioned that you have not received your student ID yet, you can still create a Microsoft account with your personal email, but it may not grant you access to the Azure services designed specifically for students.
If you are using a personal email address and encountering an "invalid" login error, it is recommended that you try to obtain your university email address as soon as possible. This email is essential for verifying your student status and accessing the Azure for Students program. Once you have your university email, you can create a Microsoft account using that email to gain access to the Azure services.
If you continue to have trouble, you may want to contact your college's administration or IT department for assistance in obtaining your student ID or email address.
