provider IOutlookCalendarProvider

An object implementing the IOutlookCalendarProvider interface.


The following code illustrates the implementation of the custom outlook calendar provider, that enables you to filter outlook objects before they are imported to the Scheduler.

The filter is set to import appointments for the current week only. More specifically, the following appointments are imported:

  • all simple non-recurring appointments within a specified week interval;
  • all series of recurring appointments if any of these appointments occur during a specified week (note that series are imported in their entirety, including simple occurrences and exceptions).
