I set up a 2003 Server running Exchange 2007 and did some resource checking noticed there are a few which seem to be running abnormally large. The top 3 with their sizes are: Edgetransport.exe 156MB w3wp.exe 151MB Microsoft.exchange.pop3.exe 115MB The utilization isn't bad at all, but the memory size is huge! Is this normal for these processes? -Keith
