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.

You can limit the access the SimpleSYN server gets to certain Outlook folders. Follow these steps:

  1. Switch to your SimpleSYN client computer
  2. Click on the menu point “Synchronization Settings“
  3. Click on “Advanced Client Settings“
  4. Activate the check box  “Restrict available folders to selected folders“

Then choose in the folder list which folders the server can have access to. To do so check the check boxes next to the folders.

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

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.

SimpleSYN can not be used to synchronize between a POP3 account and an IMAP account. Use the same account type on the PCs (either POP3 or IMAP).

If you use a POP3 account on all PCs, you can also synchronize the e-mail folders (for example, Inbox) with SimpleSYN.

If you use an IMAP account on your PC, then the e-mail folders are automatically synchronized by default, since an IMAP account is server-based. The e-mail folders of an IMAP account should therefore not be selected in addition to the synchronization, since otherwise it can lead to complications with SimpleSYN (as of version 5, e-mail folders of an IMAP account are also no longer selectable). If you use an IMAP account, SimpleSYN allows you to synchronize all other local folders (such as tasks, calendars, contacts, or notes).

    If you want to exit SimpleSYN if Outlook is closed, follow these steps:

    1. Right-click on the SimpleSYN icon in the Windows notification area and choose “Exit”
    2. Close any Outlook window
    3. Open the SimpleSYN Add-In configuration file with a text editor like notepad. The configuration file can be found in:

      At Version 4:
      C:\Users\[User name]\AppData\Local\SimpleSYN\4.0.0.0\[Outlook profile name].addin.config

      At Version 5:
      C:\Users\[User name]\AppData\Local\SimpleSYN\5.0.0.0\[Outlook profile name].addin.config


    4. Add the following code in the section between <appSettings> and </appSettings>:
      <!-- SimpleSYN is exited when Outlook is being closed. -->
      <add key="AutoExitSimpleSyn" value="true" />
      <!-- SimpleSYN is started if the Add-In is being loaded. -->
      <add key="AutoStartSimpleSyn" value="true" />
    5. Open Outlook again.

    Category: Installation, Version 4.x

    In that case, you probably have an Office 365 version from the Microsoft App Store installed.

    Programs from the Microsoft App Store can not currently recognize SimpleSYN version 4 (these programs are isolated from the rest of the system). Office 365 version from the Microsoft App Store supports SimpleSYN version 5.

    Please reinstall Outlook / Office at https://www.office.com/setup

    Then everything should work and go through the installation.

    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:
