Outlook 2003

Hello. I emailed a distribution list as an attachment to someone who is
also using Outlook 2003/Exchange server. I attached the list using the Item
choice when I click on the Insert a File toolbar button drop-down list.

The problem is when they receive the email the attachment shows up as a
message attachment and when they open the attachment there is nothing inside
it and it appears like an attached email message and not a contact
attachment. I have tried sending it in HTML and Rich Text formats but the
results have not changed.

Thanks for any input you can provide.
