This may be an easy question to answer but I don understand why this has happened. I have a user that was just upgraded to a new windows 7 32bit machine from an xp machine. The user ha outlook 2007 on both machines. When she clicks on contacts in the left hand pane under "all outlook items", their distribution lists show there. When the user click "to" when composing an email those distribution lists are not showing up in the list. How can i correct this?
