You can delete all or some recurring events from the IQ calendar(s) using the Delete action. Use the Remove from Outlook action if you only want to remove the recurring events from the Outlook calendar(s). When you delete a single recurring event, use the same procedure as you would for deleting a non-recurring (individually added) event. If you want to delete all recurring (child) events from the schedule or schedules on which they occur, you must delete the parent event.
To delete a recurring event:
Click the Calendar tab and click the Recurring Events submenu link. All recurring events scheduled for your default calendar appear.
Select the check box next to the event you want to delete.
Select the Delete action.
Click OK in response to the confirmation message.
