Category: Installation, Version 4.x, Version 5.x

SimpleSYN requires an active internet connection for its operation. The internet connection is required to connect to a central server operated by SimpleSYN. This server is used to help in the establishment of a direct connection between the SimpleSYN server and SimpleSYN client. Only data required for establishing the connection is transferred via this central server. After establishing an connection, SimpleSYN uses the best connectivity available.

If SimpleSYN Business is used to synchronize via the Internet and it is impossible to create a direct connection between SimpleSYN server and SimpleSYN client, e.g. because of Firewalls NAT or Routers are blocking the direct connection, SimpleSYN uses a relay server as a last resort. This relay server allows SimpleSYN to communicate even if only outgoing traffic is allowed from your networks.

In either case the connection between SimpleSYN will always  use an SSL/TLS encryption respectively.

Your Outlook data is never transferred in clear-text nor stored permanently on our Internet servers (no Cloud).

Note: SimpleSYN only supports proxy servers as of version 5. In all previous versions, SimpleSYN must communicate with our servers located at services.simplesyn.net.
