Hi,

Is this a one time thing? If so, try this:

In Outlook, pull up your Contacts folder
Click on New Contact Group
Name the new contact group
Click on Add Members
Choose From Outlook Contacts
Find each contact from your Excel list
When finished, click OK, then Save & Close

If this is not a one time thing, or you wanted to simply highlight a bunch of contacts then click a magical button to add all those selected contacts to a new contact group, that's what the Distribution List Manager add-in is for.
