An Azure platform as a service offer that is used to deploy web and cloud applications.
Hi Aniket,
AADSTS16000 with the Microsoft Services tenant is a known behavior when a personal Microsoft account signs into Azure without an associated Entra directory. Microsoft Q&A guidance confirms that this tenant is restricted and does not provide normal Azure resource access.
For Azure for Students, the important part is whether your student subscription was actually provisioned. If All Directories shows no directories and there is no Azure subscription, this does not look like a normal sign-in/cache issue.
Since you also cannot open Help + Support, I would contact Azure Account/Billing Support outside the portal and provide the Trace ID, Correlation ID, timestamp, and your student verification details. Azure allows support requests for subscription/account issues, although portal submission requires appropriate subscription access.
Also, because the account was recently compromised, mention that separately and complete Microsoft's account-security recovery steps. I would not create another Azure account or tenant until Microsoft confirms the status of the existing Azure for Students enrollment.
