Question

I have no other Azure AD account, I cannot add myself as an external user from within the tenant.

How do I sort out this issue

The error means your personal Microsoft account (e.g., @msn.com, @outlook.com) does not exist in the Azure AD tenant and cannot access the application.

If you have no other Azure AD account, you cannot add yourself as an external user from within the tenant. .

Hey there, Drew Bignell

So that I can try and help or point you in the right direction, please can you answer the following questions:

Is anyone else an administrator on your tenant?

When was the last time you had signed into your tenant?

When you sign into the Azure portal, here: https://portal.azure.com , does it show your tenant?

Normally, when you sign into the Azure portal, it will load the portal on a tenant your account belongs to. If you have multiple tenants you belong to, it will load the tenant you were last signed into. When you sign into the Azure portal, please look towards the top-right corner where it displays your username/email and the tenant you are currently signed into.

If your account doesn't belong to a directory, it should display an error telling you that your account does not belong on tenant 'Microsoft Services' as it doesn't belong to a tenant.

Is that the error you are seeing?

Thanks,
Nathan

Hi Nathan,

Thank you for your reply to my question.

I'm getting the error above when I try to log into azure but I'm trying to log into Power Automate.

A few years ago I setup a task to put attachments from certain emails into onedrive. The task has been working well but I wanted to login and make some adjustments.

This is the error I get when I try to log into Power Automate: Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application '6204c1d1-4712-4c46-a7d9-3ed63d992682' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account.

I don't have a different account and I don't understand what it means when it says use a different account. Sometimes the error says use a work or school account but I only have my personal msn account.

Is anyone else an administrator on your tenant? No

When was the last time you had signed into your tenant? Could be 2 years ago

When you sign into the Azure portal, here: https://portal.azure.com , does it show your tenant? No, I just get an error

Kind regards,

Drew

Hey there, Drew

It sounds as though the account has been removed from the tenant and that you have lost access to this tenant. I am going to escalate this for a Microsoft External Agent & Moderator so they can collect information on your tenant. They can pass this to the appropriate team who can try and recover your tenant.

Thanks,
Nathan

Sign in to your personal Microsoft Account and go to your Account Settings, then Security settings, and use the Log Out Everywhere link. This will remove authorization from Microsoft Flow / Power Automate to use your account's connectors, and the flows will fail to run. Then setup an account with 'Make' https://www.make.com/en this will be much easier than trying to navigate Microsoft.

Hello @Drew Bignell,

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. User's image

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:

Open an in-private/incognito browser window (to avoid automatic sign-in via SSO).
Navigate to https://azure.microsoft.com/en-us/free/ to sign up for a free Azure account.
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.

User's image

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

Hi Raja,

Thank you for the above information.

I wasn't asked to create a new directory (tenant) during the process listed above.

I'm still getting this error when trying to log into Power Automate:

Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application '6204c1d1-4712-4c46-a7d9-3ed63d992682' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account.

Kind regards,

Drew

Hello @Drew Bignell,

To better understand the behavior, could you please confirm if you are able to sign in to the Azure portal? https://portal.azure.com/

If you have not tried yet, kindly attempt to sign in once and let us know the outcome. Additionally, please share your login email address via private message for further investigation.

I have no other Azure AD account, I cannot add myself as an external user from within the tenant.
