Chris, first let me thank you for the post - very helpful information as we are considering implementing UM. But, just for clarification, you say that "Exchange does not journal voice mail by default", yet the TechNet doc you link to says "By default, in Exchange 2007, when you create a journal rule to journal e-mail messages sent to or from recipients or senders in an Exchange organization, voice mail and missed call notifications that are generated by Unified Messaging servers are included". I checked my transport config setting for this, which hasn't been altered, and found that the VoicemailJournalingEnabled setting is set to True, apparently by default. Are you referring to this setting, or to something else in Exchange that would be preventing the journaling of voicemail by default? Thanks again.
