Hi, I am running Exchange 2003 withSP1 on Windows 2003 with SP1. Many users are experiencing slow response from outlook, they are getting popup message "outlook is trying to retrieve data from exchange server." Some times it is taking a long time to open an email message. I ran perfmon to monitor RPC Averaged Latency and RPC requests counters. The max value of RPC Avg Latency is 317 and max value of RPC request is 19. I also ran EXMon but I don't knowwhat to look in the results. Are there any standard results that I can compare with ExMon results? Any help will be appriciated.
