SYMPTOMS

When you use Outlook 11 to connect to a Microsoft Exchange Server 2003 e-mail server by using a remote procedure call (RPC) over HTTP, Outlook 11 may perform slowly or stop responding (hang).

CAUSE

This issue may occur in one or both of the following scenarios:

The Bypass proxy server for local addresses check box is selected in the Microsoft Internet Explorer options, and the HTTP connection to your Exchange Server 2003 e-mail server can be made through the HTTP proxy server on the network that you are connected to. Outlook 11 has issued a local RPC call that is waiting for a remote RPC call to complete. This problem is more noticeable when you are using a slow network connection.
