Returns a RecurrencePattern object that represents the recurrence attributes of an appointment or task. If there is no existing recurrence pattern, a new empty RecurrencePattern object is returned.
expression.GetRecurrencePattern
expression Required. An expression that returns an AppointmentItem or TaskItem object.
This Visual Basic for Applications (VBA) example uses CreateItem to create an AppointmentItem object. The RecurrencePattern is obtained for this item using the GetRecurrencePattern method. By setting the RecurrencePattern properties, RecurrenceType, PatternStartDate, and PatternEndDate, the appointments are now a recurring series that occur on a daily basis for the period of one year.
An Exception object is created when one instance of this recurring appointment is obtained using the GetOccurrence method and properties for this instance are altered. This exception to the series of appointments is obtained using the GetRecurrencePattern method to access the Exceptions collection associated with this series. Message boxes display the original Subject and OriginalDate for this exception to the series of appointments and the current date, time, and subject for this exception.
For a description of changes required for this example to work in Microsoft Visual Basic Scripting Edition (VBScript), see the Note at the end of the example.

Note For this example to work properly in VBScript, there are only a few simple changes that need to be made in the code.
You don't have to retrieve the application as an object and you must use the values of the constants, so:
Set myOlApp = New Outlook.Application
Set myApptItem = myOlApp.CreateItem(olAppointmentItem)
becomes:
Set myApptItem = Application.CreateItem(1)
and
myRecurrPatt.RecurrenceType = olRecursDaily
becomes:
myRecurrPatt.RecurrenceType = 0
and
Set myFolder = myNamespace.GetDefaultFolder(olFolderCalendar)
becomes:
Set myFolder = myNamespace.GetDefaultFolder(9)
