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.

    The SimpleSYN business version can be started by a Windows service. If the option "Start as Windows service" is activated in the advanced options, then SimpleSYN automatically starts in the background when the Windows starts, without a Windows user having to log on to the system.

    The SimpleSYN standard version 4 and all older versions do not support Windows service. The synchronization takes place here only if a user is logged on to the computer and SimpleSYN is executed.

    Please check the following things:

    1. Select the right Outlook version in SimpleSYN under Options -> Advanced Options under “Outlook version”. Save the settings and restart SimpleSYN again
    2. Make sure neither Outlook nor SimpleSYN is started with administrator rights
    3. Check if SimpleSYN and Outlook are using the same Outlook profile. You can see the Outlook profil in SimpleSYN in the main window > Options
    4. Finally, if the behavior still occurs, then make an Outlook repair installation (Important: choose a full repair installation, if you use Outlook 2019, 2016 or 2013) on this computer

    Current information when SimpleSYN can no longer be started after an Office 365 update. More information.

    In this case there is an problem on the file "SimpleSYN.config", so SimpleSYN can not be started anymore.

    To repair SimpleSYN on this computer, please follow these steps:

    • Open a Windows Explorer and navigate to this directory:

      For Version 4:
      C:\Users\[Username]\AppData\Local\SimpleSYN\4.0.0.0\SimpleSYN

      For Version 5:
      C:\Users\[Username]\AppData\Local\SimpleSYN\5.0.0.0\SimpleSYN

    • In this directory you will find the file: “SimpleSYN.config” (may also be shown as just “SimpleSYN” without the extension .config).
    • Delete this file
    • Restart SimpleSYN

    Then SimpleSYN starts normally again. You would then need to activate SimpleSYN only once with your license file.

    If you no longer have the license, contact our support.
