Unity 3.1.1 UM license (but used as VM with on-box Exch 2000) with CCM 3.2.2c.
I have 2 subscribers (out of ~300) to whom outside caller messages sometimes are processed as undeliverable & sent to the unity admin. The caller hears the user's greeting and leaves his message normally. Inside callers work OK, as do some outside callers.
I've seen ~6 instances of this problem, always to these 2 subscribers, noone else. The subscriber accounts were recently created manually (not bulk added) along with several others and the others work OK.
I don't see anything obviously wrong in any of the settings, but I'm missing something, obviously.
The NDR that's forwarded to the unaddressed messages distribution list should give you a reason for the non delivery (i.e. mailbox limit exceede, mailbox unavailable, address doesn't exist etc...) - do you have that information? There's nothing on the Unity side of the configruation that would result in us bouncing the messages - we simply hand off to Exchange to deliver as normal. If the message is not delivered it's usually a full mailbox issue, DNS issue causing MTA problems or the Exchange server is unavailable/off line for an extended period or something similiar... looking at the NDR itself will give you a clue where to look next...
The voice message just appears in the admin mailbox with an address of Unaddressed Messages (Unity_@...). I access this as a POP client and there is no message body -- just a wav enclosure that is the sender's message.
