When I go to ToolOptionsE-mail OptionsAdvanced E-mail Options, I'm able
to select

"Suggest Names while completing To,CC, and BCC fields.." box that you are
if you want name autocompletion

The problem is that one of my computers with Outlook 2003 don't have this
feature which is preventing me from enabling name autocompletion. Is there a
Property setting I can customize to put this option on that machine. Please
advise. Thanks!
