Chosing services to sync from exchange server

Dear em-Client Team,
I have switched from apple mail when upgrading my laptop as I cannot use the behavior of the new apple mail for my different business / private activities. In apple mail, I could chose which services to sync from a managed exchange server (e.g. mail, but no contacts,…). I do not see this option in emClient - where can I find it ?
Background: I am also teaching part-time at an university, and now the whole address book (with all students) shows up, when I compose an email.
Thanks,
Chris
