I'm not sure what I am supposed to do first.

I wrote a letter to be merged with some of my outlook contacts. I
already copied those I needed into a new sub Contacts folder in
Outlook.

However, when I try to insert merge fields, the Middle Name is not
on the list. I haven't done this in a year and I forgot what to do.
How do I get all the outlook fields, or at least the fields in that
particular view, which included middle name, to appear on the Insert
Merge Field List?
