Ask another administrator of the Azure tenant to set Block sign in to No for your Microsoft Entra user; if you are the tenant’s only administrator, open a support request from another account for tenant-access recovery.

Access to account.microsoft.com shows that the personal Microsoft account itself remains accessible, but Azure can authenticate the same address against a separate Microsoft Entra tenant user. Personal and organizational identities can appear to use the same sign-in address while remaining distinct accounts.^1^

If another tenant administrator exists

Ask a Global Administrator or User Administrator for the Azure tenant to:

1. Sign in to the Microsoft Entra admin center.
2. Go to Entra ID → Users.
3. Find and select your affected user.
4. Select Profile.
5. Under Settings, change Block sign in to No, then save.
6. Confirm that the user object is enabled and retry the Azure portal sign-in in a private browser window.

Microsoft documents this account-status check and requires at least the User Administrator role.^2^ A matching Azure portal lockout case was resolved by having the tenant’s Global Administrator unblock the user.^3^

If Azure redirects to an employer, university, or other organization’s sign-in page, that organization owns the relevant tenant user and its administrator must unblock or remove it.

If you are the only administrator

This cannot be repaired through account.microsoft.com, because that portal does not administer the tenant-side Entra user.

1. Use a different working Microsoft account to contact Microsoft Support.
2. State that:
   • You are locked out of your Azure tenant.
   • No other Global Administrator can sign in.
   • You need tenant-access recovery.
3. Include the affected tenant ID, the sign-in address, the approximate failure time, and the complete error text.
4. Complete the identity and tenant-ownership verification requested by the Data Protection team.

The supported escalation path for a sole administrator is Microsoft Support/Data Protection; recovery requires proving identity and association with the tenant.^4^

Do not create a replacement tenant if the existing tenant contains subscriptions or resources you need—the new tenant would not restore access to those resources.
