Is there a way to figure out where in the system a message became unaddressed or undeliverable before ending up at the Unaddressed Messages distribution list?<br><br>I know some of the possible causes are full/missing exchange mailbox or orphan call handlers, but I dont think thats the cause. I do suspect my operator user or operator call handler may be contributing to the 6 12 messages a day Im getting. Is there a log or event entry recorded that would help, or is my best bet to walk through call handlers and Exchange settings looking for possible causes?<br><br>Thanks for any advice<br>- Mark<br><br>System Info:<br><br>Unity 3.0.(3)<br>TSP 3.0.4<br>CM 3.1.2c<br>100 subscribers / 8 ports<br>Exchange 2000 (separate box)<br><br><br>
