Sync SharePoint contact list to all Exchange users personal contact list

view story

http://serverfault.com – We have users who have centralised their contacts in a SharePoint list. They would like to access this list on their phones, synchronised over ActiveSync. Is there any software which will sync from a SharePoint list to an Exchange user’s personal contact list? If not, then an option to use Exchange public folder is OK (although I don’t know how one would do this). (HowTos)
