How do I add mass information from excel to contacts in Outlook?

[LauraHutton]

I have 909 potential buyer's emails as contacts on Microsoft outlook. I have
their names and email addresses, but I also want to add all their phone
numbers, addresses, companies and locations; information which is all located
in an excel spreadsheet I already have.
How do I move all relevant information across, and hopefully onto the right
person?

You will have to write a custom script.

For each row in your spreadsheet,
find the Contact in Outlook,
copy the phone numbers, etc., from the Excel row to the Contact,
save the Contact
