Estimados amigos,
Desde hace unos días estoy experimentando un error a la hora de sincronizar a través de Active Sync los buzones de Exchange desde fuera de mi organización. El acceso por Owa y RPC funcionan perfectamente pero falla Active Sync.
Mi configuración se compone de un Windows Server 2003 STD con Isa Server 2004 en un servidor y otro con Windows Server 2003 STD con Exchange 2003 SP2 y Directorio Activo. Todo funcionaba correctamente hasta que un día dejaron de soncronizar.
He pasado el "Test Exchange Connectivity" y el resultado es el siguiente:
"Testing Exchange ActiveSync
Exchange ActiveSync test Failed
Test Steps

Tell me more about this issue and how to resolve it

He revisado todos los pasos que la propia aplicación recomienda pero no han dado resultado. También he borrado y creado de nuevo los directorios virtuales de IIS sin obtener resultado positivo.
¿Alguien me puede ayudar?
Gracias y un saludo,
