I am running Exchange 2003 SP2 enterprise on Windows server 2003. There are 80 users running Outlook 2003
Recently, i have noticed that Outlook is slow to respond and often reports that it is waiting to communicate with the exchange server.
I have downloaded exTRA and run performance troubleshooter. It has reported that i have extremely high RPC Operations per second. The scan was run on a sunday morning when there were only 2 users logged on. When i logged one the users off and re run the scan i don't get the warning. This particular user has a large mailbox (3GB), does not have cached exchange mode enabled and also uses google desktop. However he is also an awkward senior employee so unless i can have some cast iron evidence he is causing the problems there is not a lot i can do.
Can anybody advise whether there are other tools i can use to pin point what my problem may be?
