ActiveSync allows a mobile device to be synchronized with either a desktop PC or a server running a compatible software product including Microsoft Exchange Server, Axigen, Horde, IceWarp Server, Kerio Connect, Kolab, Novell GroupWise, Tine 2.0, Scalix, Zarafa/Kopano via Z-push, or Zimbra. On desktops, ActiveSync synchronizes emails, calendar, contacts and tasks with Microsoft Outlook, along with Internet bookmarks and files. ActiveSync does not support all features of Outlook. For instance, contacts grouped into subfolders are not transferred. Only the contacts which are not in a subfolder are synchronized. In case of Exchange Server, only emails, calendar, contacts and tasks may be synchronized.
