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

  • Open a Windows Explorer and navigate to this directory:

    C:\Users\[Username]\AppData\Local\SimpleSYN\4.0.0.0

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

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

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.

SimpleSYN requires a unique configuration and a unique certificate for each PC.

SimpleSYN must be completely reset to one of the clients. Then SimpleSYN can be reinstalled and set up.

Follow these steps:

  • Uninstall SimpleSYN first under the Windows Control Panel "Programs / Features" or under Apps on Windows 10
  • Then enter the following line in Windows Explorer:
    %localappdata%
  • Find the folder SimpleSYN here and delete this folder.

Then delete the SimpleSYN certificate as follows:

  • Open the Internet Explorer
  • Go to "Internet Options"
  • Click the "Content" tab
  • Click on "Certificates"
  • In the next window under "Display name" search for the SimpleSYN entries, mark the respective entry and click on "Remove"

Then you can reinstall SimpleSYN and set it up again. The initial synchronization will be run once again.

Close Outlook and SimpleSYN on the PC and then restart both applications.

If the behavior persists after that, check the following points:

  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.

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.

You can easily upgrade Outlook (or Office). The previous version does not need to be uninstalled. SimpleSYN automatically detects the new Outlook version.

Note:
Install Outlook in the same bit version as the previous version, either in 32-bit or 64-bit.

If you want to install Outlook in a different bit version than the previous version, first uninstall SimpleSYN and reinstall SimpleSYN after the Outlook update.

Provided you have made changes to the default settings of the color categories, you will have to manually set up the list of color categories (formerly main category list) identically on all computers. The category list is not synchronized by SimpleSYN. The assigned categories in the items, however, are kept and synchronized by SimpleSYN.

In version 6 the function "Add new categories to master category list" is available..

If this option is activated, SimpleSYN checks whether all categories used in the items are present in the master category list during synchronization. If not, SimpleSYN adds the category name to the master category list with a default color. You can manually adjust the color to match the other PCs.

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.

SimpleSYN requires the following outbound TCP connections.
