CodeTwo Exchange Sync - Version 2.2.4 CodeTwo Exchange Sync enables automatic synchronization of various Microsoft Exchange Server folders. It offers extended syncing options to Exchange Server users , e.g. synchronizing Public Folders with personal mailboxes or handhelds. While most smartphones do not allow syncing with Exchange Public Folders, CodeTwo Exchange Sync is capable of doing it within seconds. The program supports one-way, two-way and folder-ring synchronization. What is more, synchronized data can be modified on the fly. In One-Way sync, as the name suggests, data is synchronized in one direction only. The next available synchronization type is Two-Way. In this option, data replication goes in two directions so synchronized folders always contain the same elements. When multiple folders are synchronized in the Two-Way mode, a "folder ring" is created - it is the third synchronization type. Data from each folder is replicated in all other folders from the ring.
