Hello @lina.p ,

Thank you for reaching out on Microsoft Q&A.

I understand that you are encountering the AADSTS16000 error while attempting to log in to Microsoft Entra ID. This issue typically arises when trying to sign in to the Microsoft Entra admin center using a personal Microsoft account that is not associated with any directory.

Since you mentioned using a private email address, this error occurs because personal accounts are not natively recognized within Entra ID tenants. To resolve this, it is recommended to log in with a work or school email that is already added to the tenant.

If you prefer to continue using your personal email address, it must first be added as an external user by a Global Administrator of the tenant. The administrator can follow the steps outlined in Microsoft's official documentation on https://learn.microsoft.com/en-us/entra/external-id/b2b-quickstart-add-guest-users-portal. Once the invitation is sent, you will need to accept it to proceed.

If your account has already been added as a guest user but the issue persists, clearing the browser cache, closing the browser, and attempting to sign in again may help resolve the problem.

If the issue persists, feel free to provide additional details, and I’d be happy to assist further.

Hello @lina.p,

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: Whenever you sign in Azure portal using Microsoft Personal Account you by default get connected to the Microsoft Services tenant (f8cdef31-a31e-4b4a-93e4-5f571e91255a).

You can also confirm this by navigating to Microsoft Entra ID > Overview blade and you can see f8cdef31-a31e-4b4a-93e4-5f571e91255a as Tenant ID.

In this default tenant, you do not have any directory associated with it which you can confirm by navigating to settings.

User's image

As this is a standard tenant without any directory associated, you cannot perform actions such as creating new users, groups, enterprise applications, and so on. To perform administrative actions, you must have administrative access to the tenant.

Solution: For this purpose, you need to create your own tenant rather than using the Microsoft Services (f8cdef31-a31e-4b4a-93e4-5f571e91255a) tenant.

To create a new tenant, open in-private/incognito browser window (just to avoid SSO), access https://azure.microsoft.com/en-us/free/ to create a free Azure account.

User's image

When you create a new tenant, you by default become the Global Administrator of the new tenant and have full access to all the options in that tenant.

If you still want to access Entra portal using your personal Microsoft account only, you can invite that user as a guest user as mentioned here : https://learn.microsoft.com/en-us/azure/active-directory/external-identities/add-users-administrator#add-guest-users-to-the-directory and assign the Global Administrator role.

Once you are added to an azure tenant and you accept the invite sent to you via email, you can use https://portal.azure.com/#create/Microsoft.AzureActiveDirectory URL to create your own tenant as well.

Hope this will help. Please "Accept the answer" if the information helped you. This will help us and others in the community as well.
