As you have already stored your private contacts in the Outlook Contacts, it makes sense to use them for sending fax messages:
·Open a new e-mail and click "To" - The dialog below opens
·Choose the address book the contact is stored in (e.g. Global Address Book or your private contacts)
·Search for the contact you want to send a fax to ("Type Name or Select from List")
·Choose e.g. Peter Smith (Business Fax). The additional information in brackets makes it easier for you to distinguish between e.g. a phone number and the fax number.
·Click "To" and the name is displayed in the field "Message Recipients"
·If you have finished your selection, click "OK"
