I have a client with an SBS08 server(Exch07) complaining of slow internal mailflow. I'm recording about 90-120 seconds from send to delivery on all messages at seemingly any time of the day. I've run through some of the message tracking and performance monitors. The server did make mention that there were a higher than normal amount of RPC connections. I ran the suggested Exmon tool but am not seeing abnormally high connections. But perhaps i just don't know how to use the tool to get to the info i need.
Messages are not sitting in the outbox. Can you all help me diagnose the problem and what's holding up these messages?
