Question

I accidentally change my only user type to 'internal' now I cannot access my tenant or change settings

TASVA EV 0

I accidentally converted my user from an external account to an internal account in Microsoft Entra ID, and now I am unable to access any of the services in Azure Portal and Entra admin center.

When I tried to access my original tenant (https://portal.azure.com/<ORIGINAL-TENANT-ID>) and opened the Entra ID, I was given this message:

interaction_required: AADSTS16000: User account '{EUII Hidden}'; from identity provider 'live.com'; does not exist in tenant '<TENANT NAME>'; and cannot access the application '74658136-14ec-4630-ad9b-26e160ff0fc6'(ADIbizaUX) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account. Trace ID: <TRACE ID> Correlation ID: <CORRELATION ID> Timestamp: 2025-10-13 11:41:46Z"

Hello TASVA EV,

Error AADSTS16000 is thrown when the user not found in the tenant used for authentication. In your case, this error usually occurs when you sign in to Azure Portal using your personal account which is not added as an external/guest user to an Azure AD tenant. Due to this, you by default get connected to the Microsoft Services tenant.

Since you are connected to the Microsoft Services tenant as a standard user with restricted access, 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.

For this purpose, you need to create your own tenant rather than using the Microsoft Services tenant. 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.

To create a new tenant, open in-private/incognito browser window (just to avoid SSO), access Create Your Azure Free Account Or Pay As You Go | Microsoft Azure to create a free Azure account.

Once the new account is created, you should be able to see and switch to the new tenant by clicking on the settings icon as highlighted below:

In some cases, the user might already have an active session that uses a different personal account than the one that's intended to be used. Or they have a session that uses their organization account although they intended to use a personal guest account (or vice versa).

In that scenario, try signing in to the Azure Portal trough a tenant-specific URL using the following format:

https://portal.azure.com/<tenant domain name>

Eg.

https://portal.azure.com/constoso.onmicrosoft.com

Hello, I still do not have the issue resolved as I do not have my internal user id. Could you please share it privately so I can use it to login and add my user.
