The RecurrencePattern properties of Interval, DayOfMonth, DayOfWeekMask,
MonthOfYear and so on are used for that. The result in RecurrencePattern may
not match what you see in the dialog since it's translated when you click
OK.
Use F2 to look at the properties in the Object Browser and use the VBA Help
to see code samples for that.

Thanks for the help, I have managed to map the dayly and weekly options on
the recurrence pattern but I am not sure which properties store the monthly
option. I know that frequency is stored in the interval property but do you
know where the day and the week in the month (e.g. third week) are stored ?

Those mask properties are used for that. Each is a flag of bits. You have to
interpret the bits of DayOfWeekMask, DayOfMonth, MonthOfYear.
