Support Request for AADSTS5000228 Tenant Access Denied

Question

Dear Microsoft Support,

I created a trial account to test Azure AD, but I am unable to access the tenant because I receive the following error:

Error Code: AADSTS5000228 Message: Tenant access is denied

Answer 1

The error AADSTS5000228: Tenant access is denied indicates that access to the Microsoft Entra ID (Azure AD) tenant is blocked at the tenant level, so sign-in to that tenant is not allowed.

For a trial tenant, this typically means one of the following:

1. The tenant has been made inaccessible (for example, due to inactivity or an internal block), and sign-in is no longer permitted.
2. The tenant is in an inactive state and may be on the path to deletion.

When a tenant is made inaccessible due to inactivity, Microsoft Entra returns a similar error and blocks all access. In such cases:

• Administrators can request reactivation only within a limited time window after the tenant becomes inaccessible.
• If the tenant remains inaccessible beyond that window, it is deleted and cannot be recovered.

To proceed:

1. Confirm whether the tenant is still within the reactivation window.
2. If administrator access is needed and the tenant should remain active, the tenant administrator must contact Microsoft support to request reactivation and review options.
3. If the tenant is no longer needed or has already passed the reactivation/deletion window, no further action is required; a new tenant can be created instead.

Because tenant-level access blocks cannot be lifted by end users, resolution always requires working with Microsoft support as a tenant administrator.
