Error 5.7.705: acceso denegado, el inquilino ha superado el umbral
Saludos.
Tengo un cliente que ha superado el umbral de correos salientes
, debido a que parece que le robaron las credenciales, creando muchos usuarios y a parir de ahí enviaron más de 15K correos. Por lo tanto, Microsoft ha bloqueado él envió de correos.
Ya he estado aplicando los pasos para comprender el motivo https://learn.microsoft.com/es-es/exchange/mail-flow-best-practices/non-delivery-reports-in-exchange-online/fix-error-code-5-7-700-through-5-7-750
¿Alguien tiene experiencia en este tipo de caso?
Me pueden ayudar explicando como lo han solucionado. El cliente está en España.
EmmRoHe I understand that the tenant was blocked from sending emails due to compromised account and you need to have it resolved.
If you are receiving an NDR of 5.7.705: Access denied, tenant has exceeded threshold, you need to log a support request from the Office 365 Admin Center as Microsoft can only be the one to release the tenant.
But before you log a support request, please make sure of the following:
- Reset the password of the compromised account
- Enable multifactor authentication on one of the global administrators and make sure that it is properly set up as this would be a requirement by the support representative to have the tenant released
- Delete unfamiliar inbound connectors (From the Exchange Admin Center -> Mail Flow -> Connectors)
- Delete unfamiliar transport rules (From the Exchange Admin Center -> Mail Flow -> Connectors)
- Delete unfamiliar inbox rules on the compromised account (Login using the compromised account -> Open Outlook Web App -> Settings -> View all Outlook Settings -> Mail -> Rules)

Thanks Deleted it's great have you answer. The same time I talking with support of Microsoft. And part of you answer doing for this solution.
Adicional, dentro de Azure Active Directory en la sección Administrar / Registros de aplicaciones / Todas las aplicaciones se eliminó la aplicación que aparecía en esa área.
