If users are unable to play voice mail messages received from Exchange 2007 Unified Messaging, do one of the following:
Ask users to download the Windows Media Player 9 for Mac OS X from the Windows Media Player 9 for Mac OS X
page on the Microsoft Web site (microsoft.com) and then play the voice mail message. The message will play in Windows Media Player
instead of from within Entourage.Change the format of the audio codec on the Exchange 2007 Unified Messaging from .wma to .wav, and then play the voice mail message from within Entourage. Exchange 2007 Unified Messaging can use any of the following three audio codecs to create and store voice messages: Windows Media Audio (WMA), Group System Mobile (GSM) 06.10, or G.711 Pulse Code Modulation (PCM) Linear. The WMA audio codec creates .wma audio files and the GSM 06.10 and G.711 PCM Linear audio codecs produce .wav audio files. For more information about Exchange 2007 Unified Messaging audio codecs, see Understanding Unified Messaging Audio Codecs
