I understand now what Outlook does with the Business Address field. My problem now is, my data base as each address field seperated. Address_1 is Street, Address_2, City, State, Zip, ect. I unmapped Address_1 from Business Address and left all the others. Outlook Address Detail is now correct with exception to I am missing the Street (Address_1) field. Genisus does not allow more than one field per Outook field. Do I need to edit my database table to join these fields and map to Business Address?
