I'm starting with a .TXT file in Windows but it's external from
Outlook. The file contains names and email addresses, approx 25 to 50
names. Here is a sample of the .TXT file (my real file is
fixed-column, but it might not appear that way in this message)

Miles Smith
Michael Dell
Steve Ballmer
etc

I know one way to import the file into an Outlook distribution list,
but what is the best or correct way?

With the names in the format you describe, Select the entire list,
right-click and choose Copy. The in Outlook, click NewDistribution List,
then click Select Members. In the Members field, right-click and choose
Paste. Click OK. The names and addresses will be inserted properly into
the DL. I just tried to make sure.
