This Visual Basic for Applications example creates a task called "Oil Change" that recurs every three months and uses the Regenerate property to set it to regenerate after each recurrence.
Set myOlApp = CreateObject("Outlook.Application")
Set myItem = myOlApp.CreateItem(olTaskItem)
Set myPattern = myItem.GetRecurrencePattern
myPattern.RecurrenceType = olRecursMonthly
myPattern.Regenerate = True
myPattern.Interval = 3
myItem.Subject = "Oil Change"
myItem.Save
myItem.Display
If you use VBScript, you do not create the Application object, and you cannot use named constants. This example shows how to perform the same task using VBScript.
Set myItem = Application.CreateItem(3)
Set myPattern = myItem.GetRecurrencePattern
myPattern.RecurrenceType = 2
myPattern.Regenerate = True
myPattern.Interval = 3
myItem.Subject = "Oil Change"
myItem.Save
myItem.Display
