I have Windows Vista Business with Office professional 2007.
I am using a Sony Vaio and Palm Treo750 for mobile sync.
How do i disable :
Windows Calendar
Windows Contacts
Windows Mail
In order to set outlook 2007 to default in all areas which would also
make the sync facility easier to use and control.
