Property set:


Long ID (LID):


Data type:




This property specifies the dates and times when a recurring series occurs by using one of the recurrence patterns and ranges detailed in [MS-OXOCAL]. The value of this property also contains information about both modified and deleted exceptions; information such as dates, subject, location, and several other properties of exceptions. The binary data in this property for recurring calendar items is stored as the AppointmentRecurrencePattern structure. This property must not exist on single instance calendar items.

There are some limitations to recurrences:

  • Multiple instances must not start on the same day.

  • Occurrences must not overlap. Specifically, an exception that modifies the start date of an instance in the recurring series must occur on a date that is after the end of the prior instance and the start of the next instance in the recurring series. The same is true if the prior or next instances in the recurring series are exceptions.

The schedule of a recurring series is determined by its recurrence pattern and range.
