3.1.4.6.3 Dismissing for Recurring Task Objects

To dismiss a reminder for a Recurring Task object, the client MUST set the PidLidReminderSet property (section 2.2.1.1) to FALSE and SHOULD<15> set the PidLidTaskResetReminder property ([MS-OXOTASK] section 2.2.2.2.6) to TRUE.

For Task objects, if the value of the PidLidReminderTime property (section 2.2.1.4) is in the future, the client SHOULD set the PidLidReminderSignalTime property (section 2.2.1.2) to the same value as the PidLidReminderTime property so that the reminder will be signaled at the appropriate time for the next instance.

Dismissing a reminder for a Recurring Task object never causes an instance to become an exception.
