When selecting the UPDATE option for an Outlook 2007 distribution list, the
list does NOT update. We also had this problem in earlier versions of
Outlook. For example, we change the email address for one of the contacts
in the distribution list, open the distribution list and select the update
function, but the email address is not updated for that contact. We have
tried updating both without selecting a contact and with selecting all
contacts. Any suggestions on what the problem might be?
