• Disable integration of Instant Messaging in Outlook: From Outlook, click on "Tools" in top menu, click on "Options", click on "Other" tab, and make sure that "Enable the Person Names Smart Tag" is unchecked.

• Make this registry change to speed up the startup and operation of Outlook: click here to download this file and execute it. In Internet Explorer, choose "Open" after clicking on the link. Accept the warning prompt about importing data into the registry. NOTE: Do this ONLY if your network is running TCP/IP protocol only (ask your system administrator if you're unsure).
