I am trying to sync my contact group for phone at my work. The outlook is connected to Exchange Server and a copy of outlook.ost is maintained on local drive "C". It seems that Apple support people are clueless about "OST" Vs. "PST" files. In setup, info tab, sync contact, I can only select all contact radio button. The select group button is gray and cannot be selected even when I have the two different contact group in outlook. Anyone with knowledge on outlook with exchange could shed some light. Thanks.
