Scheduled sync properties determine when and how frequently messaging-based synchronization occurs. These settings apply to Windows Mobile devices only.
Consider hospital employees that work different peak hours, depending on the shift they work, and have a Patient MBO that updates staff of changes in the health and treatment of each patient. The administrator may have multiple templates for each shift group, as well as the role each group performs at the hospital. For example, nursing staff may not require frequent updates during off-peak hours when they are away from the hospital and would set the off-peak frequency at 1 hour. However, the nursing staff would require almost immediate updates while on shift, as frequently as they happen. Surgical staff or "on call" staff may require frequent updates even when they are not on shift at the hospital, wherein administrators, may keep the peak frequency at "As Items Arrive", but also set the off-peak frequency to "As Items Arrive" to ensure patient information remains up-to-date on the device.
