I have a contact that used to have the email address X but I have
changed the address to be Y. When I look at the address in my
contacts, I see it correctly as Y. But whenever I add the contact to
a distribution list, it still uses the old address X. I know it uses
the old one because when I view the distibution list, there's a two-
column list (the left column is the name and the right is the address)
and it shows the old address in the right column. When I send an
email to the distribution list, it sends it to the old address.

Thanks in advance,
John
