CodeTwo FolderSync Addin

Synchronize folders in Microsoft Outlook for free

CodeTwo FolderSync Addin

CodeTwo FolderSync Addin is an Outlook add-in that lets you synchronize data between Outlook folders. The synchronization process always takes place between selected folders only, and the user can choose several pairs of folders he or she needs to be synchronized.

Please note that if you have Exchange Server in your organization and you want to synchronize its folders (from any mailbox) automatically giving the administrator control over all the synchronization tasks, try out CodeTwo Exchange Sync. This freeware can synchronize data between selected folders in real time while being totally transparent to the end-users. Any changes made in one folder are instantly and automatically copied to the folders selected by an administrator.

CodeTwo FolderSync Addin - synchronization

During the synchronization process, the program does not compare the data in selected folders. However, it does store IDs of previously synced items. Therefore, during the first synchronization of two folders, a sum of their contents is created in both of them. All items from folder 1 will be transferred to folder 2, and similarly the data from folder 2 will be added to folder 1. If prior to the first synchronization, both folders contain identical items, these items will be duplicated and must be removed manually.

If a pair of folders has been synchronized and in both folders some changes are made at the same time on the same item, the item that has been modified later will prevail if the folders are synchronized again.
