There are two different types of polling cycles:
The full synchronization poll is controlled by the scheduling set on the CRM policy for the peak and off-peak intervals and the blackout times.
Every interval goes through each enabled module checking for changes in the CRM and the email system.
To complement the full synchronization poll, the drop folder poll checks only the SmartConvert "Create New" and the AssignTo folders for changes. This poll does not check the contacts, calendar, or tasks.
Configuration in Riva 2.4.23 or Higher
In Riva 2.4.23 and higher, the synchronization policy includes options on the Scheduling tab to control the functionality and frequency.
Configuration in Riva 2.4.21 and 2.4.22
In Riva 2.4.21 or 2.4.22, configure the following advanced options in the sync policy:
Crm.FastSyncDisabled = true
To modify the drop folder poll interval, represented in minutes:
Crm.Ex.FastSyncPeakInterval = 5
Crm.Ex.FastSyncOffPeakInterval = 15
