In Exchange 2007 Unified Messaging, there are no options exposed within the Exchange Management Console that would allow an administrator to configure broadcast or announcement capabilities for voice mail messages. For example, let’s say that you need to send a voice mail message to your entire staff announcing a mandatory meeting later today. There really is no easy way to configure this functionality in the current release – but it can be done, thanks to the following solution provided by Wayne Harper, a Senior SEE for the UM escalation team in Las Colinas, Texas.
Hope this helps!
