Outlook 2007 provides several options that control how it stores and displays contacts. To view these options, choose Tools, Options, and then click Contact Options on the Preferences tab. In the Contact Options dialog box, shown in Figure 18-30, you can configure the following options:
Default "Full Name" Order. This option specifies how Outlook 2007 creates the Full Name field when you click Full Name in the new contact form and enter the contact’s first, middle, and last names, along with suffix and title.
Default "File As" Order. This option specifies the name that Outlook 2007 uses in the card title. Outlook 2007 uses the information you specify for first, middle, and last name—as well as company—to create the card title based on how this option is set.
Check For Duplicate Contacts. Select this check box if you want Outlook 2007 to check for duplicate contacts when you create new contacts.
