When I try to login on azure portal getting error-

Hello dilip kumar,

Based on your description, it appears that you have created a Microsoft personal account, not an Azure work or school account. This is why you’re encountering errors when trying to access the Azure Portal.

Issue: When users try to login to Azure portal using their personal Microsoft Account (Outlook, Hotmail..) they are getting AADSTS160021 or AADSTS16000 or AADSTS50020 errors.

Reason: When signing in to the Azure portal with a personal Microsoft account, you are automatically connected to the Microsoft Services tenant (Tenant ID: f8cdef31-a31e-4b4a-93e4-5f571e91255a).

You can verify this by navigating to Microsoft Entra ID > Overview, where you’ll see this Tenant ID.

This default tenant does not have a directory associated with it, which you can confirm by going to the Settings blade. As a result, you cannot perform administrative actions such as:

• Creating users or groups
• Registering enterprise applications
• Managing resources

In short, it’s a system tenant with restricted capabilities, and administrative access is not granted by default.

Solution: To fully utilize the Azure portal, you need to create your own tenant instead of relying on the Microsoft Services tenant.

Follow these steps:

1. Open an in-private/incognito browser window (to avoid automatic sign-in via SSO).
2. Navigate to https://azure.microsoft.com/en-us/free/ to sign up for a free Azure account.
3. During the setup, you’ll be prompted to create a new directory (tenant). Once completed, you will become the Global Administrator of this new tenant, giving you full access to manage Azure resources.

Let me know if you need help with the sign-up process or configuring your new tenant.

If you already have an existing tenant and still unable login, please share your email address over private message which used to login into Azure Portal.
