In Microsoft Outlook, a feature notifies users that the connection to the Microsoft Exchange Server computer is taking longer than expected because of network congestion or server availability. This connection can include connections to the user's mailbox, to a free and busy server, or to any other server with which Outlook may need to communicate to fulfill a request for information.
When such a delay occurs, the following Cancel Request dialog box is displayed:
Outlook is retrieving data from the Microsoft Exchange Server server_name. You can cancel the request or minimize this message to the Windows taskbar until Outlook closes the message automatically.
You may want to disable this feature or to increase the time-out value if you experience frequent network congestion or other related issues.
To suppress the Cancel Request dialog box or to change the time-out value, you can manually edit the registry or use a policy to configure the setting.
