I created a Microsoft account using the personal email . Until recently, I was able to log into both the Azure Portal and the Microsoft Entra Admin Center without any issues.

However, I am now encountering the following problems:

I can log in to the Azure portal, but when I navigate to the Users section (to create or manage users), I receive an error.

When I attempt to access the Microsoft Entra Admin Portal, I am immediately shown an error and cannot proceed further.

Please note:

This is the main account associated with the tenant.

I have not created any additional users in this account in the past.

I have attached relevant screenshots of the errors I am receiving for your reference.Screenshot 2025-06-12 125108

Hello @Prakash More

Thank you for contacting Q&A Forum. You are experiencing two errors at the same time so let's analyze it one by one:

Error 1: "The portal encountered an issue while attempting to retrieve access tokens..."

This typically means your session has expired or there’s a problem with your authentication tokens. The key part is: AADSTS160021: Application requested a user session which does not exist. This can happen if your session timed out or there was a change in your account or tenant configuration.

Error 2: "Selected user account does not exist in tenant 'Microsoft Services'..."

This means your Microsoft account is not recognized as a user in the Microsoft Entra tenant. The Entra Admin Center is trying to access a tenant where your account is not registered as a user or guest.

You can try the following troubleshooting methods:

  • Check Tenant Context: Go to https://portal.azure.com > Click on your profile (top-right) > Switch Directory. Make sure you're in the correct tenant where your account is the administrator and if your account is still associated with the tenant.
  • Verify Account Type: If you used a personal Microsoft account, it may not have full access to Entra ID features unless explicitly added as a guest or external user in the tenant.
  • Use Microsoft 365 Admin Center: Try logging in at https://admin.microsoft.com. If you can access it, check your role under Users > Active Users > Your Account.
  • Try logging in from a private browser or clear cache again.

Kindly let me know if this work for you and please let me know if you have any further questions.

If I have answered your question, please accept this answer as a token of appreciation and don't forget to give a thumbs up for "Was it helpful"!

Hello Prakash More,

Thanks for your question

So this is a AppSessionSelectionInvalidSessionNotExist error which means Application requested a user session that doesn't exist. i.e it is logging in to an account that does not exist. To resolve

  • Try logging into a private/incognito tab or a different browser. Preferrably edge Inprivate
  • Also try Clearing browser cache and cookies

    Hello Prakash More,

    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:

    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.
