The Exchange 2000 Conferencing Web Scheduler may permit a user to book a meeting with an incorrect duration or recurrence schedule. For example, a user may be able to book a meeting with a duration of four days every day. The Conferencing Web Scheduler permits the user to schedule the meeting, which is not valid.
This problem occurs because the Conferencing Web Scheduler does not follow the Microsoft Outlook model for booking a meeting.
