Frequency

For the Calendar and To-do resources, a distinction is made between a fast scan and a full scan. As the name implies, the fast scan is a quick way to see if any change has occurred in the immediate future. The full scan is a more thorough, but also more time consuming process.

For Calendar and To-do resources, a synchronization is scheduled if:

• Fast scan: A calendar entry for today or tomorrow is changed.
• Full scan: Any calendar entry is changed within the entire span of time defined in the client settings (the synchronization window).

For all other resources, there is no difference between fast and full scans.

The frequency setting does not apply to schedules that are based on Exchange subscriptions. Every 45 minutes a process is run to verify and clean out unused subscriptions.
