When the StartTime property value and the StopTime property
value are programmatically set for the Exchange_ScheduleInterval WMI class, the
StartTime property value and the StopTime property value become read-only and
cannot be modified.
Note This behavior does not cause any loss of functionality for the
public folder replication schedule.
To replace the StartTime property
value and the StopTime property value, you must delete the
Exchange_ScheduleInterval WMI class and then re-create the
Exchange_ScheduleInterval WMI class with the new StartTime property value and
with the new StopTime property value.
If you want to add additional
intervals of time to the Exchange public folder replication schedule, you must
create a new instance of the Exchange_ScheduleInterval WMI class by using the
SpawnInstance() method.
