And Outlook's display of these phone numbers is not only hard coded, but hard
coded absolutely correctly. Australian mobile numbers do have an area code;
it's "4" by the way, not "04". The "4" is the Australian area code reserved
for mobile numbers, it's not part of the local number. The "0" is not part of
the phone number or the area code. It's a "trunk code" or "dialing prefix".
So when Outlook displays an Australian mobile number like this: +61 (4)
xxxxxxxx, in fact it's displaying it correctly.
