CloudLink server requirements

Last published : Apr 17, 2026
For optimal performance we recommend that you install the CloudLink application on a standalone server or virtual machine. We recommend that you do not install CloudLink on an Active Directory domain controller, due to the potential effect on performance.
Note: If you use CloudLink for Exchange or Domino account synchronization, you must install a separate instance of CloudLink for Google account synchronization.
