Azure login error

Question

Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application 'PII' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account.
I get this error when trying to sign in with my personal account in Azure. I have tried multiple browsers and clearing the cookies and at this point i do not know what to do anymore.

Answer 1

The error indicates that the personal Microsoft account is trying to access a tenant where it does not exist as a user, or the wrong identity/tenant endpoint is being used.

Use these steps to resolve it:

1. Confirm which identity is being used
   • The message shows tenant Microsoft Services. That is the default tenant used when signing into Azure/Entra with a personal Microsoft account (Outlook/Hotmail/OneDrive) that has no Azure tenant of its own.
   • In this default tenant, there is no linked directory where portal actions can be performed. This behavior is expected for personal accounts.
2. If the goal is to administer Azure/Entra (have a directory/tenant)
   • A separate Azure tenant must be created and associated with the personal account.
   • Follow the documented steps to create an Azure account and new tenant:
     1. Browse to the Azure account website and select Try Azure for free.
     2. Complete the sign-up flow.
     3. A new tenant is created and the account becomes Global Administrator in that tenant, which then allows full access to Azure/Entra resources in that tenant.
3. If the goal is to access an existing app/tenant as a guest
   • The error text explicitly states that the account must be added as an external user first.
   • Ask the administrator of the target tenant (the one hosting the application with ID c44b4083-3bb0-49c1-b47d-974e53cbdf3c) to:
     • Invite the personal account as a guest user to that tenant, following the standard guest invitation process.
   • After the invitation is accepted, sign out of all sessions and sign back in, then access the application again.
4. If sign-in loops or wrong account keeps appearing
   • Completely sign out of all Microsoft identities and clear cached sessions:
     • Close all browser windows.
     • Open a private/incognito window.
     • Go to the sign-out URL for Microsoft cloud services (as documented) to ensure all sessions are cleared.
     • Sign in again with the intended personal account.

If, after these steps, the same message still appears when accessing a specific organization’s resource, the administrator of that organization must either add the account as a guest or provide the correct sign-in URL/tenant for that resource.
