For optimal performance, we recommend that you install the Folder Sync application on a standalone server or virtual machine. We recommend that you do not install Folder Sync on an Active Directory domain controller, SQL Server computer, or Exchange server, due to the effect on performance.
If you use ArchiveTools CloudLink, you can install Folder Sync on the CloudLink server, if that server meets all of the requirements of Folder Sync. If you install CloudLink and Folder Sync on the same server, then before you run either application, log in to the associated application's service account. For example, always log in to the Folder Sync service account before you run the Folder Sync application.
The computer on which you install Folder Sync must be on the same primary domain as the Exchange Servers with which it communicates.
Table: Folder Sync server requirements specifies the other requirements for a server on which you install Folder Sync.
Note: Some of these requirements are new for recent versions of Folder Sync. Before you upgrade Folder Sync, make sure that your server meets the latest requirements.
