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

With SimpleSYN Standard or Business you can synchronize Outlook between 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).

I have purchased a SimpleSYN Lifetime License Version 1. Can I also use the current version 2 with this license?

SimpleSYN Mobile Lifetime licenses in version 1 are unfortunately not valid for the main version 2.

With a lifetime license, you will not incur any additional costs per month/year. The license entitles you to use the licensed version (e.g. version 1.0) indefinitely. Minor updates (eg version 1.0 to version 1.0.1 etc.) are included. Major upgrades to new versions (eg version 1.x to version 2) are subject to a fee, but optional.

Subscription include upgrades to new main versions in addition to minor updates.

If you are interested in version 2, you can also test the new main version free of charge for 30 days.

You do not need any additional apps on the mobile device, not even the Outlook app (not supported).

Use the integrated standard apps of the respective system on your mobile device: :

ForAndroidApple iOS / iPadOS
EMails Gmail app Apple Mail app
Tasks Gmail app Apple reminders app
Appointments Google calendar app Apple calendar app
Contacts Google contacts app Apple contacts app
Notes

Android devices do not have a built-in default app for managing notes.
Therefore, you need to use a third-party app on your Android device

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.
