I have a client who has a spreadsheet of about 4000 contacts with the
columns mostly of the usual data: name, biz phone number, email addy,
etc. But for each contact (spreadsheet row), there is is also about 18
custom fields (columns), such as square footage, expiration date, etc.

The problem is importing this xls spreadsheet of contacts into Outlook:
how to get all the custom fields to show up. I know I can custom map
about four user defined fields per contact during the import process.
But as mentioned before, there are about 18 such fields.

Can someone point me to a reference that will allow me to do this
easily? Or is this the province of Outlook programmers? Or ???

Thanks in advance, much appreciated.
