You need SimpleSYN Standard or SimpleSYN Business and also SimpleSYN Mobile.

With SimpleSYN Standard or Business you can synchronize Outlook between multiple Windows PCs. If you still want to synchronize mobile devices (smartphones, tablets), then you also need SimpleSYN Mobile.

With SimpleSYN Mobile you can synchronize Outlook on a Windows PC with up to 5 devices (smartphones, tablets).

In the standard configuration (both in the Business and Standard versions), SimpleSYN requires an active Internet connection. SimpleSYN uses this connection to contact a central server operated by SimpleSYN, which facilitates the connection between the SimpleSYN server and the SimpleSYN client.

Only the information necessary to establish the connection is transmitted — your Outlook data is never stored in the cloud. Afterward, SimpleSYN attempts to establish a direct connection between the participating installations. The best available connection method is selected automatically.

All communication is always encrypted using SSL or TLS. Outlook data is never transmitted in plain text or permanently stored on our servers — it is only forwarded directly and securely.

Why does the Standard version also use this method?
Since most users today have an internet flat rate, we decided to use the central server in the Standard version as well — however, with the limitation that the connection is only established within the local network.

Using SimpleSYN without an Internet Connection

If you would like to use SimpleSYN without an internet connection or without our central server, then there is the option of changing the connection configuration so that our central server is no longer necessary.

Important:
This setting is primarily intended for the Standard version. In the Business version, synchronization will only work within the same local network after switching to this mode — synchronization over the internet will no longer be possible.

How to activate the custom connection (from version 5):

  1. Open the SimpleSYN main window.
  2. Go to Options > Advanced Options.
  3. On all PCs (server and clients), enable the option “Custom connection mode”.
  4. On each client, enter the computer name or the static IP address of the SimpleSYN server in the field “Custom server name/address”.

First, empty the Deleted Items folder in Outlook if you no longer need the items.

Also check in the SimpleSYN main window under “Options > Advanced Options” how the “Remove backed up items” selection is set under “Backup”. If the entry is set to “never”, then set a different selection (e.g. after 14 days). Save the changes.

The SimpleSYN backup folder in Outlook is then automatically reduced in size in the background and the old backups are deleted.
