The icon difference does not matter. It does indicate that many of your
members were actually created in an earlier version of Outlook which is also
why the Update Now button will never work.

I have a distribution list that is not updating. Updates were made to
distribution list members' email addresses, but they are not updating when
I
click on the "Update Now" button. Also, in front of the members' names,
sometimes there is an icon that looks like a rolodex card and sometimes
there
is an icon with 2 faces. Why the difference? Does it matter?
