Actually with iPhone i set my zimbra account as exchange and everything works...

On the Mac, instead, setting Exchange doesn't work...

I just read that Lion (OsX 10.7) will support Exchange 2010: does this mean we will have full exchange support on Macs too?

I don't need it for exchange, but just for sync my devices with calendars and contacts.

Thanks for any answers that can drive me in the correct direction!
