Hi Elle,
I presume you are using a CSV file from Excel to Outlook
addressbook. Double check your work by creating or
verifying that everything in an item in your address book is
correct. Then Export that address book, and when you do be sure
to check off each item that you use when exporting, including
first name, middle name, last name, full name. Check the column headings,
you must use *exactly* the same column heading as the addressbook uses.
Also check in your test exported file that the full name matches the
first name + middle name + lastname. If the box comprised
of those names is filled in instead of the components you will
have a difference and should see that difference when exported,
or when you sort on first name or sort on last name you see
that the first and lastnames were not properly distinguished.
Now what was that about programming that you mentioned,
did you use a macro, and why does the subject title mention
mail merge.
The main problem people have with mail merge is that the
worksheet used was not moved to the first worksheet tab
position in the workbook.

Because of the apparent discrepancies could you please verify
if your problem was solved and specifically what the problem was.
