SYMPTOMS
When you book online meetings on the Exchange 2000 Conferencing Server, you may be able to overbook a resource.



CAUSE
This problem may occur because Conference Management service (CMS) publishes conferencing resources asynchronously.

When the Conferencing Server starts, it processes the meetings that are scheduled on the global calendar, and then determines the resources that are available. This process occurs asynchronously, meaning that the process may occur at the same time that the rest of the conferencing services start. This asynchronous process makes it possible for a user to schedule a new meeting by using a resource that may not be available. This process results in a conflict or overbooking.



RESOLUTION
To resolve this problem, the conferencing administrator must monitor the Event Viewer Application log to make sure that conferences have not been scheduled before the resource calculations have completed.

The following event ID message is logged in the Application log when resource calculations start: Event ID: 16388

Source: MSExchangeCONF

Category: CMS Internal Description: The Conference Management Service is updating the availability of existing conference resources. Scheduling online meetings during this time can cause resources to be overbooked. User Action Wait until the update is complete before scheduling a meeting.

The following event is logged when resource calculations have completed: Event ID: 16389

Source: MSExchangeCONF

Category: CMS Internal Description: Conference resource availability has been updated.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
