As technologies and security needs have evolved, some of the original McAfee Agent scheduler options have become unnecessary or no longer work as originally intended.
MA 5.x removes support for two scheduler options with its release:
To accommodate MA 4.8.x installations and tasks upgraded from earlier ePO versions, both options remain available in the task scheduling interface. But, although these options are selectable, MA 5.x client installations
do not honor these options, even if they are enabled in existing tasks. To maintain expected task execution on MA 5.x clients, you must either create tasks without these scheduler options or modify existing tasks accordingly.
