XADM: Event Agent Fires Every 15 min If No Schedule Is Defined

When installing an Event Agent to a folder in Exchange 5.5, the user can select the "A scheduled event occurs" event handler. If the user does not click Schedule and define a specific schedule, the Event will fire on a 15 minute interval, however, the expected behavior is that this event would not fire at all.

When the user checks the Scheduled Event properties page, the Schedule is set to Hourly, with the Run Event set for Every 0 hour and 0 min.

Explicitly click Schedule and define a specific schedule.

Microsoft has confirmed that this is a problem in Exchange Server 5.5 for Alpha. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
