In the outlook address book, I have three different groups of contacts each with around 500 entries. When I sync contacts in Mobile Me. One of my outlook contact groups consistently does not sync. If I log into mobileme, I can see the two other groups. I have tried resynching and resetting the sync preferences in the control panel. If I create a new group in mobile me, the new group will sync and appear in outlook. Any suggestions. Thanks Iain Grant Windows XP, Outlook 2003, MobileMe.
