Taken right from the outlook 2002 white paper:
Cancelable
Server Request
Outlook has a new dialog box that shows the user when Outlook
is waiting on a response from the Microsoft Exchange Server or Active Directory
Global Catalog server. This dialog has a Cancel request button so users can
cancel the request and continue to use Outlook.
Users who do not want the
dialog box to be displayed on screen can use the check box to minimize it. This
dialog does not necessarily indicate a problem condition - just that the server
has failed to respond to a request by Outlook in a specified amount of
time.
Change the Timeout of the Cancelable RPC
Dialog
If the Cancelable RPC dialog appears too often on a slow
link and interferes with the user's ability to work, change the default timeout
value so that the dialog does not appear as often. Changing the amount of time
until the server communication times out is done by altering the Exchange Server
Settings. Exchange Server Settings are altered in the same way described in the
Choose the Connection Type at Start Up section.
Microsoft tried to remove
as many RPC's as they could to increase performance of the application.
They
couldn't actually remove them, so they changed it so the RPC's only show up when
called upon.. On slow links you see this message box more.

Yea, the popup box is just an interface
for a highly complex backend that
sifts through bad RPCs

What?
It's
not a "cheat". It's an informational message. And RPC's are most
certainly not "removed".

Actually Ill tell ya
what is goin on.
That status bar is new to XP.
That status bar was MS'
way of removing RPC's that slow the client down.
If you were using
Outlook XP on your lan, and your lan was slow, or were on a 10 MB switched
environment, you would see that bar come up again. Its a cheat on MS' side to
try and speed up your client. -----Original Message-----

Exchange 5.5 SP4 on NT4 SP6
Outlook XP and Outlook
2000.
My coworker and I are trying to determine how Outlook really works.
We have noticed that when we are dialed up on our laptops and connected to our
network via an IPSEC VPN connection (same with PPTP), when we connect to
Exchange via Outlook XP there are times we get a message that it is requesting
information from the server and has a status bar. Under Outlook 2000 there was
no information box like that.
My argument is that under XP, it is telling
you that is requesting information and this is normal operation, given that it's
working on a dialup. I should clarify, that we get this box when we are trying
to open email or change folders. He says this is some kind of error that needs
to be resolved.
Can some one shed some light on this. If you need more
information please let me know.
