error code -89467458 cannot log in

The error message in the screenshot indicates that the directory object quota limit for the tenant has been exceeded. This prevents new sign-ins or directory operations until the quota issue is resolved.

Because this is a tenant-level quota problem, it must be fixed by the tenant administrator in Azure AD/Microsoft Entra ID or Microsoft 365:

1. Contact the Microsoft 365/Azure administrator for the tenant shown in the error.
2. The admin should review the tenant’s directory object usage and quota in the Azure portal (Microsoft Entra ID):
   • Check how many directory objects (users, groups, service principals, etc.) are in use.
   • Delete unused or stale objects to reduce usage.
   • If the tenant is legitimately at capacity, request an increase of the directory object quota through Microsoft support.
3. After the quota is reduced or increased and directory operations succeed again, retry the sign-in.

If not the admin, provide the full error text (including “Directory_QuotaExceeded” and the request ID) to the admin or support so they can open a support case with Microsoft if needed.
