Outlook client delays

[Cody]

Hello folks, lately all the outlook clients in our office are getting random
popup message saying "Outlook is trying to retrieve data/information from
Exchange Serve" and causing delays in sending/recieving emails. We are using
Exchange 5.5 sp4 for mail server and Outlook XP sp3 for clients. Please help
if there is a workaround for this problem.

That generally means one of two things:
a) a network problem
b) the server has a problem

For the server I suggest using performance monitor and watching things like
CPU utilization, and RPC counters. If you see high CPU utilization you know
right away that you have a problem and you will need to figure out what is
causing it (anti-virus/anti-spam products are notorious for being CPU hogs).
If CPU is reasonable then check RPC. Check RPC requests and RPC
operations/sec. If RPC requests is consistently higher than 10 you users
will likely get the popup. A combination of high RPC requests + low RPC
operations/sec usually means something is wrong - the server is having a
problem with something. High + high just means it is very busy.
