You can't, and I don't see why you would want to. The chances of being able
to maintain and use a DL of 500 members are next to 0. Import the entries
into your Contacts Folder and then use a reliable way to group those
Contacts, such as categories or a separate Contacts subfolders.

I need to import a 500 item list which I have as a xls and csv file
into a Distribution List and not the general Contacts address book.

If I try as a xls file, it asks for a range. I read the help file but
it makes no sense.

If I try with a csv file, I have to Map before the import will happen
but nothing coincides.

My excel file has 4 columns, first name, middle initial, last name,
email address.

How do I do the above?
