I want to schedule tasks using multiple resources.  The work task is fixed and multiple resources are allocated to the tasks.  I want to auto-schedule the tasks, however, when 1 resource is unavailable (i.e. through using exceptions in 'change working time').   I want MS project to automatically delay the task until ALL  resources are available to complete the task.  i.e. I don't want MS project allocate the task to the 1 resource and the duration extended.  Can anyone help?
