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.

E-Mail folders of IMAP accounts (eg Inbox or sent objects) are hidden in the "Synchronization settings", since IMAP already keeps the e-mail folders in sync (IMAP is server-based).

You can use SimpleSYN for all other local folders such as calendars, contacts, tasks, notes, etc.

If you also want to synchronize e-mail folders with SimpleSYN, then use a POP3 account on all PCs.

Category: Operation, Version 5.x, Version 6.x

When using the automatic synchronization it is also possible to synchronize all Outlook® subfolders automatically. The Outlook® subfolders will use the same synchronization direction and settings as their parent folder. Changes to the folder hierarchy below a selected folder are being synchronized.

Changes of the selected parent folder are not automatically synchronized. If a selected parent folder is being moved or deleted, the synchronization of this folder and all of its children will stop and is marked with a red X in the synchronization settings.

If you would like to continue synchronizing this folder at the new location, check the assignment of the folder in the synchronization settings on the client PC and save the page.

Moved subfolders are being deleted and completely resynchronized on the remote computer Deleted folders are also deleted on the remote side; all data inside the folder will be deleted in this case.

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.

No, the trial version has no restrictions whatsoever; you have access to the full potential of SimpleSYN. There is merely a dialog window on startup informing you how many days you have left on the test version, which you have to manually confirm.  You can use and test SimpleSYN for 30 days, for free and noncommittal. After the trial period has ended SimpleSYN cannot be started.

Category: General, Version 4.x, Version 5.x, Version 6.x

The SimpleSYN Business Version, in addition to all the features of the standard version, offers:

  • Synchronization over the Internet.
  • Filter function - for synchronizing certain Outlook items.
  • Windows service - start SimpleSYN automatically even if no user is logged on to Window.
  • Advanced synchronization options for reminders, categories and read status (version 6 and newer).

Category: Operation, Version 4.x, Version 5.x, Version 6.x

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.

Category: Operation, Version 4.x, Version 5.x, Version 6.x

The synchronization is not carried out in specific intervals, but rather as needed. As soon as the SimpleSYN client and SimpleSYN server have a connection the synchronization is carried out continuously and virtually in real-time.  After the initial synchronization only changes to the Outlook database are exchanged. The Outlook synchronization runs automatically in the background.

Example: If a new e-mail is received, an existing e-mail is changed, deleted of moved, SimpleSYN will immediately synchronize this action on all computers. SimpleSYN checks if the target folder already contains the e-mail. If the e-mail does not exist it is synchronized into the folder. If the e-mail already exists it will only be synchronized if a change has occurred. If the target computer is not reachable, the e-mail is synchronized as soon as the computer establishes a connection over the local network.

Category: Purchase, Version 5.x, Version 6.x, SimpleSYN Mobile, Version 1.x, Version 2.x

You purchase the desired license quantity on the website and initiate the order transaction, then follow the instructions. 

Note for SimpleSYN Standard/Business:
You`ll need a license per computer you want to synchronize. For example: If you wish to synchronize Outlook between your laptop and your desktop computer, you will need two licenses. If you want to synchronize 3 computers, you`ll need 3 licenses, etc. If you want to use SimpleSYN on a terminal server with different users, you need a license for each user.

Note for SimpleSYN Mobile:
With a license you can activate SimpleSYN Mobile on a Windows PC and synchronize up to 5 end devices (smartphones, tablets). If you want to use SimpleSYN Mobile on several Windows-PCs, you need additional licenses.
