Exchange UM broadcast / distribution voice mail

Microsoft’s Dave Howe posted a great tip to his blog: how to allow users to send voicemail messages to multiple users. This is often called “broadcast” or “distribution” voicemail, because the sender specifies a single address that expands into multiple recipients– just like a conventional distribution group in Exchange. The process is pretty straightforward: you create a new AD distribution group for the target recipients, update the UM grammar files that Exchange UM uses for speech recognition, and start sending messages.
