I appreciate your help.  I'll just create a work around.  

I like exporting Outlook Contacts to Excel because you can see all the
fields at once and can use the Excel file to more easily create complex
custom mail merges.  I also find that mail merges with Excel files work more
predictably than merges with Outlook Contacts.

As mentioned, the address book sort is correct.  No problems with the "File
As" in this case.  The problem is when adding an address via "To" to a new
message.  It seems that Outlook is "concatenating" Address Book fields  
"Title," " First Name" and "Last Name" into the "Name" column (field)
displayed.

Wouldn't you agree, it's frustrationg.  I mean if Microsoft can't get the
import/export functionality right, why include it?  When I re-import the
Excel to Outlook, I am careful to ensure that all fields are mapped corectly.
That's all that should be required.  Why should it require more than that?

I know programming is complex and testing software under real world
conditions is even harder.  But, Outlook performed as I described, and it's
repeataqble, as described.  You may not want too try the procedures yourself,
because you know import/export is quirky but someone on the Outlook
development team should.  All programers must ensure that the functionality
they provide performs according to design and more importanly is in-line with
the users mental model.  (Heck, the team can contact me, I be happy to
participate in their user experience/ interaction design tests.)

Stay well,
