Enabling the Contacts Box in Outlook 2007

In Microsoft Office Outlook 2003 and earlier, there was a box next to the Category section at the bottom of an appointment where I could add contacts. I can't seem to locate that box in Microsoft Office Outlook 2007. Is that feature available in Outlook 2007?

In Outlook 2007, the Contacts box for linking items to contacts doesn't appear by default. However, you can enable it by clicking Tools, Options, Contact Options, and then selecting the Show Contact Activity Information on All Forms setting. That setting is also available in Group Policy Editor (GPE) after you download the Outlk12.adm file from http://www.microsoft.com/downloads/details.aspx?FamilyID=92d8519a-e143-4aee-8f7a-e4bbaeba13e7, and load it into the Office Configuration Tool. The following GPE setting controls this registry entry:

Key: HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Outlook\Preferences

Value name: ShowContactField

Value type: DWORD

Values: 1 = show Contacts controls, 0 = Don't show Contacts controls (default) 

The Office Configuration Tool setting controls the same registry value in HKEY_CURRENT_USER\
Software\ Microsoft\Office\12.0\Outlook\Preferences. . . .
