There is a document from Microsoft which addresses this issue: http://www.microsoft.com/exchange/techinfo/deployment/2000/OutlkImp.doc (Page 16)
Excerpt: When a send and receive task takes a noticeable amount of time, Outlook displays an improved progress dialog box. This dialog box provides more detailed information about send and receive operations than was available in previous versions of Outlook. The following sections describe additional improvements to send and receive performance within Outlook 2002. Fewer Exchange 2000 Remote Procedure Calls (RPCs) Results of load testing indicate that the use of Outlook 2002 produces 17 percent fewer Exchange remote procedure calls (RPCs) than previous versions of Outlook in the same online usage scenarios. Outlook uses RPCs to retrieve data from or send data to Exchange. Less Data Transmitted to the Exchange 2000 Server Test results indicate that Outlook 2002 transmits and receives 20 percent fewer bytes to and from Exchange than previous versions of Outlook in the same online usage scenarios. Fewer Delays If Outlook 2002 cannot immediately complete an RPC, it notifies you of the delay. The Requesting data from Microsoft Exchange Server dialog box displays the progress of the RPC, and provides you with the option of canceling the call. For example, if Outlook 2002 cannot contact Exchange, you can cancel the call and try again later. The Requesting data from Microsoft Exchange Server dialog box To wait for the call to complete, minimize the dialog box and continue to work in Outlook 2002. Continuing to work in Outlook was not possible in earlier versions of Outlook. If you do not want the Requesting data from Microsoft Exchange Server dialog box to interrupt your work, select the Always minimize this message when a delay occurs check box.
