How to add more field(s) to the personel contact so we can select on the NEW email address dialog

Hi,

I checked on the Exchange contact list and it can show the 'Company' field but the personal contact just showing 3 fields. Please advise on how to add the 'Company' field to the personal contact..

Thanks

There are a lot of fields information so I can easily find the recipient I want to email

Personal contact shows only 3 fields
