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: Proxy-Servers are not supported by SimpleSYN. SimpleSYN must communicate with our servers located at services.simplesyn.net.

SimpleSYN requires the following outbound TCP connections:

The message "destination folder was not found" appears if the top folder level in Outlook (eg "Personal folders") has been named differently on the SimpleSYN client and SimpleSYN server. In this case, SimpleSYN can not assign the destination folders automatically because no new PST files are created by SimpleSYN.

Click on the "Select a different target folder" link and select the folder where you want to sync.

Alternatively, you can name the highest folder level identically on all computers in advance.

If a computer is not reachable over network or Internet, then the synchronization is carried out as soon as the computer is back in the network or online and SimpleSYN has established a connection with the SimpleSYN server.

All Outlook items that were changed or created up to that point are automatically recognized and synchronized by SimpleSYN.
