In some circumstances (such as a Terminal Server environment), you may not have Outlook loaded on the GP server, and this can result in Outlook trying to go through the setup process each time you open GP. You can remove Outlook from your home page by going to Tools > Setup > System > System Preferences (or choose “Customize this Page” in the upper right corner of your home page). Then under “Home Page Defaults” you can uncheck Microsoft Office Outlook.
