You can easily upgrade Outlook (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.

  • 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.

If SimpleSYN cannot establish a connection make sure the following is correct:

  1. Make sure SimpleSYN is installed and started on both the client and the server computer
  2. At least one computer has to be configured as SimpleSYN server and a second as SimpleSYN client
  3. Install the latest version of SimpleSYN on all computers that are to be synchronized
  4. Make sure you have an active internet connection on both computers
  5. Check whether the time is correctly set on both computers. Set the same time on both computers.

Additionally: 

  1. Make sure the correct server has been selected on the SimpleSYN clients.
  2. Make sure the password has been entered correctly.

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 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" />

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 is a Client-/Server application. In your SimpleSYN network one PC must be configured as a server. The SimpleSYN server must be authorized in the Windows Firewall and/or Desktop firewall.

Please make sure that SimpleSYN is allowed in your personal firewall.

SimpleSYN must communicate with our servers located at services.simplesyn.net.

SimpleSYN requires the following outbound TCP connections.

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.

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 make a Outlook repair installation on this computer. Please follow this instruction:
https://support.office.com/en-NZ/Article/Repair-an-Office-application-7821d4b6-7c1d-4205-aa0e-a6b40c5bb88b

Important: choose a full online Outlook repair installation and NOT a quick repair.

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

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

  • 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.

If you want to sync multiple Outlook data files, create a separate user account for each Outlook data file. Multiple user accounts are also suitable for synchronizing different mobile devices (e.g. iPhone and iPad) with separate settings.

You can manage the user accounts individually and select which folders to synchronize for each user. Thus, it is possible to synchronize, e.g., on the iPhone only the Outlook calendar and on the iPad additionally to synchronize the contacts. 

Category: General, Version 5.x

A good start is always to remove items from the Outlook “Deleted Items” folder and also configure the SimpleSYN backup functionality to remove outdated items.

This can be done in SimpleSYN under “Options -> Advanced options -> Remove backed up items”. Here you can specify the period of time after which the items are to be permanently removed from the backup folder.

Category: Version 1.0

For setting up the synchronization on the device, a special SimpleSYN Mobile account of the type "Exchange ActiveSync" is created.

During the first synchronization, the data is synchronized from Outlook to the mobile device. Changes made in this account after the first synchronization are always synchronized by SimpleSYN Mobile to both sides (bidirectional).

E-mails, appointments and contacts that were saved on the mobile device before the first synchronization, i.e. that are not in the SimpleSYN account, are not synchronized to Outlook because they use different accounts. If you also want to keep this data up to date in the future, make sure that this data is also available in Outlook before the first synchronization.
