What do you mean you "moved to 2003 exchange" and how did you migrate?
A fax recipient will only appear in the address book if their fax address is
valid, resolved, and resides in the same folder you are showing in the
address book view.

Since I moved to 2003 exchange, not all of my recipients with fax numbers
show up in the address book when I am sending a message as fax recipients.

SOme do but it is very spuratic. Any ideas?
