This is how you can create a distribution list...
create a new distribution in your outlook contact book (not the business
contacts list)
select "select members"
When the window opens click on "Show Names from the" drop down list on the
top right and select either business contacts or accounts and add your
contacts from there.
This will allow you to make a distribution list from the contacts in your
business contacts or accounts list.
